Cleaning methods & the science
What hot water extraction is, why water temperature and CFM matter, the acid rinse, and whether carpet can be cleaned without chemicals.
What is hot water extraction?
Heated solution goes in under pressure to release soil and oils, and vacuum pulls it back out. The cleaning is in the recovery, not the water going in.
Read the full answer →What does CFM mean in carpet cleaning, and why does it matter?
CFM measures the airflow a machine’s vacuum blower moves — the force lifting suspended soil and rinse water out of the pile and into the recovery tank.
Read the full answer →What temperature should carpet cleaning water be?
Heat is one of four variables governing soil suspension, alongside chemical action, agitation and time. Lower-heat methods compensate with the other three.
Read the full answer →Can carpet be cleaned without chemicals?
Water alone does not remove oil, and household soil is bound to fiber by oil. The real question is whether the chemistry is neutralised and extracted after.
Read the full answer →What does IICRC S100 mean?
The S100 is the industry standard for professional carpet cleaning, published by the Institute of Inspection, Cleaning and Restoration Certification.
Read the full answer →What is the correct way to vacuum carpet?
Slowly, and especially in the traffic lanes — fast passes are why a vacuum misses things. Slow passes give it time to lift sand out before it grinds the fibre.
Read the full answer →Why carpet looks worse, grays, or smells after cleaning
The real reasons carpet can look worse after a cheap clean, turn gray, bloom, resoil fast, or smell — and what prevents each.
Why does my carpet look worse after cleaning?
Three causes: wicking from the backing, residue left behind that grabs new soil, and fiber damage the soil had been hiding until it was gone.
Read the full answer →Why does carpet turn gray?
Two different things produce the same gray. One is oil — body, shoe and airborne cooking oil coating and discolouring the fiber — and that comes out.
Read the full answer →What is fiber blooming in carpet?
Permanent physical damage to carpet fiber caused by abrasion: embedded sand grinds through the protective coating with every step. Cleaning does not undo it.
Read the full answer →Why does my carpet get dirty so fast after cleaning?
Because something was left in it. Detergent that is not fully rinsed stays in the pile as a sticky residue, and it grabs soil from every shoe that crosses it.
Read the full answer →Why does my carpet smell worse after it was cleaned?
Usually because water went in and not enough came back out. Moisture left in the backing and pad sours as it dries slowly on soil that was already there.
Read the full answer →Protector, sand, lifespan & keeping it clean
Whether carpet protector is worth it, what sand actually does to the fiber, how long carpet lasts, and keeping it clean with pets.
Is carpet protector worth it?
Carpet ships with a protective coating. Sand and foot traffic abrade it away, and once enough is gone the fiber blooms and the colour change is permanent.
Read the full answer →Does carpet cleaning actually remove the sand in my carpet?
Yes — the alkaline solution releases the oil film holding the sand in place, and high-airflow extraction flushes it out. A vacuum alone cannot reach it.
Read the full answer →How long should carpet last?
Anywhere from about five to fifteen-plus years, depending on quality, traffic and, most of all, whether the oils come out before sand grinds the fibre.
Read the full answer →How do I keep my carpet clean with pets?
Staying ahead of the oils and catching urine early — vacuum slowly and often, blot accidents with plain water, and use a blacklight before it reaches the pad.
Read the full answer →Should I clean the carpet before selling my home?
Yes — one of the highest-return, lowest-cost improvements before listing. It takes out oils and sand, refreshes colour, and deals with odours a buyer notices.
Read the full answer →Stains, vinegar, rentals & store-bought removers
What really comes out, whether old stains can be removed, and why rental machines and store spot-removers often make it worse.
Can old stains really be removed from carpet?
Some come out completely and some do not, and it depends on what caused them and whether the fibre was dyed or bleached.
Read the full answer →Does vinegar damage carpet?
Diluted vinegar is generally safe for blotting some spots, but it can affect certain fibres and dyes and it will not fix deep problems.
Read the full answer →Do store-bought spot removers damage carpet?
Some contain optical brighteners — fluorescent dyes that make a treated area look brighter under light rather than removing the soil.
Read the full answer →Why do rental carpet shampooers make carpet get dirty faster?
Because they leave detergent residue behind. There is no acid rinse to neutralise the carpet and pull it out, and sticky residue grabs soil from every shoe.
Read the full answer →Do rental carpet cleaners include an acid rinse?
No. Rental and store-bought machines sell detergents and spot products but never the one step that neutralises the carpet and takes the residue back out.
Read the full answer →Why is high-pH shampoo bad for carpet?
It releases oils well and does harm if left in the carpet. Alkaline residue is sticky, attracts soil and stops protector bonding, so it has to be neutralised.
Read the full answer →Can a rental carpet shampooer cause mildew?
It can. These machines put water down and lack the suction, heat and airflow to get it back out, and moisture trapped in the pad is where mildew begins.
Read the full answer →Are rental carpet machines any good?
Not for a maintenance clean, and the two reasons are heat and vacuum. The chemistry never activates, and recovery is too weak to pull the water back out.
Read the full answer →Are home carpet shampooers better than rentals?
They share the same fundamental design. Owning one settles the hygiene question about a shared machine and none of the others — still no rinse, still no heat.
Read the full answer →Wool, shrinkage, mold & safety
Whether steam cleaning is safe for wool, if cleaning shrinks carpet, and what cleaning can and cannot do about mold.
Is steam cleaning safe for wool carpet?
It can be, with the correct temperature, the correct pH and gentle handling. But wool is sensitive, and the fibre has to be identified before anything gets wet.
Read the full answer →Does carpet cleaning shrink carpet?
Properly done, it does not shrink modern synthetic carpet. Over-wetting wool or older jute-backed carpet without strong recovery is where the risk actually is.
Read the full answer →Can carpet cleaning remove mould?
Surface growth on damp carpet may be addressed, but mould in the padding or subfloor after a real water event needs the material removed rather than cleaned.
Read the full answer →Pet urine & odor — the honest answers
How pet urine is found and treated, how to know if it is in your carpet, the vacation smell, and why we never guarantee a result on urine.
How does Spiker treat pet urine in carpet?
Enzyme solution is injected into the padding and the subfloor beneath, where urine actually settles, then flushed until the rinse runs clear.
Read the full answer →How do I know if there is pet urine in my carpet?
Urine deposits fluoresce under a blacklight in a darkened room, showing a map of what has soaked through the carpet into the pad.
Read the full answer →How do I get pet smell out of carpet?
Pet urine soaks into the pad, so surface cleaning never reaches the source. Locate it with a blacklight, flood with enzyme to that depth, extract until clear.
Read the full answer →Why does my house smell when I come back from vacation?
Odour sources in carpet, pad and upholstery stay active while a house is closed up. With no airflow, what is normally carried away accumulates instead.
Read the full answer →Tile & grout
How often tile and grout need cleaning, why grout darkens, and whether to seal it.
How often should tile and grout be cleaned?
Generally every one to two years, sooner in kitchens and entryways. The signal is the grout: once the lines look darker than the tile, the pores are loaded.
Read the full answer →Why does grout get dark and dirty?
Because it is porous and mopping actually feeds it. A mop pushes dirty water into the low grout lines, depositing grime into the pores every time.
Read the full answer →Should I seal my grout, and what kind of sealer?
Yes, after it has been properly cleaned. Use a penetrating sealer that protects from inside the pores; surface coatings tend to peel and fail.
Read the full answer →Upholstery, area rugs & mattresses
How often to clean upholstery, why a couch smells, and whether area rugs can be cleaned in the home.
How often should upholstery and couches be cleaned?
About every one to two years, sooner with animals or children. A couch absorbs body oil every time somebody sits on it, so it can look fine and smell lived-in.
Read the full answer →Why does my couch smell even though it looks clean?
Because it absorbs body oil every time somebody sits on it, plus spills, sweat and pet dander, all held deep in the fabric and the fill where you cannot see it.
Read the full answer →Can area rugs be cleaned in the home?
Many can, depending on the rug’s material, construction and condition. Delicate, antique and natural-fibre rugs need identifying before anything gets wet.
Read the full answer →Hiring a cleaner, pricing & what to ask
Whether professional cleaning is worth it, what to ask a company, how to spot a good one, and why the cheapest quote is usually the most expensive.
Is professional carpet cleaning actually worth it?
It does what a rental cannot: removes the deep oils that cause graying, rinses so the carpet does not resoil, and extracts hard enough to dry in hours.
Read the full answer →What should I ask a carpet cleaning company before booking?
Five things: solution temperature at the wand, whether they acid rinse, extraction airflow, whether the soil leaves the property, and how urine is reached.
Read the full answer →How do I know if a carpet cleaner is good?
Three tells separate a defined process from a script: do they blacklight before quoting pet work, work to the IICRC S100 sequence, and acid rinse afterwards?
Read the full answer →Why is very cheap carpet cleaning usually a problem?
A very low room rate does not cover the full sequence, and the steps that get dropped are the invisible ones: dwell time, the acid rinse, thorough extraction.
Read the full answer →How often should carpet be professionally cleaned?
It follows wear rather than a calendar, and children or pets roughly triple it. Most manufacturer warranties also require professional cleaning on a schedule.
Read the full answer →How often should I clean my carpet?
There is no single number — it depends on wear, and pets plus kids roughly triple it. The real rule is visual: if you can see discolouration, it is overdue.
Read the full answer →Why is Spiker 4.8 on Yelp when the reviews are 5 stars?
Yelp runs a filter that hides a portion of reviews on every business listing, and the hidden ones do not count toward the visible average. Google does not.

Carpet cleaning in Lodi, California
Spiker Carpet & Tile Care has cleaned carpet, tile and upholstery in Lodi for thirteen years — from the older homes downtown to the newer subdivisions, and the tasting rooms in between. These are the questions Lodi homeowners actually ask, answered for Lodi specifically.
Who does carpet cleaning in Lodi, CA?
Spiker Carpet & Tile Care serves Lodi and San Joaquin County directly at (209) 663-0823 — carpet, tile and grout, upholstery, area rugs, mattresses and commercial work, using hot water extraction (commonly called steam cleaning). Thirteen years in the area, owner-operated, trained to and operating by the IICRC S100 standard, with an honest walk-through quote before any work starts.
How do you get red wine out of carpet in Lodi?
Lodi is wine country, and red wine is the spill we see most. The honest answer: fresh red wine, blotted (never rubbed) and treated quickly, often comes out or improves substantially — but dried, set, or older wine that has bonded to the fiber or dyed it may not fully remove. We tell you what we can realistically do at the inspection, before you pay, and we never guarantee a stain will come out. Call the Lodi line at (209) 663-0823.
Does Lodi hard water affect my carpet and tile?
Yes. Much of the Lodi area runs on hard water, and the mineral content leaves residue that dulls carpet over repeated cleanings and darkens grout faster. It also changes what grout sealer will hold. This is exactly why the acid rinse matters here — it neutralizes residue and brings carpet back toward a neutral pH so it does not attract soil like a magnet. Call the Lodi line at (209) 663-0823.
Do you clean carpet in older downtown Lodi homes?
Yes, and older Lodi homes need a specific approach. Many downtown homes have original wood or delicate subfloors under the carpet, so moisture control during cleaning matters more — enough to flush the soil out, controlled enough that the carpet is damp, not soaked, and dry in hours. Newer Lodi subdivisions usually have builder-grade polyester that cleans differently. We adjust to what is actually under your feet. Call the Lodi line at (209) 663-0823.
Can you clean tasting room carpet and upholstery in Lodi?
Yes — Lodi tasting rooms and event spaces are regular commercial work for us. Red wine on carpet and upholstery, foot traffic on tile and grout, and seating that takes daily use are exactly what we handle, scheduled around your hours with a walk-through quote first. Call the Lodi line at (209) 663-0823.
Carpet cleaning in Wilton, California
The owner of Spiker lives in Wilton. That is not a marketing line — it means the carpet challenges specific to Wilton’s rural, oak-woodland properties are ones we deal with in our own home. Here is what Wilton homeowners ask, answered for Wilton.
Who is the local carpet cleaner in Wilton, CA?
Spiker Carpet & Tile Care — and the owner actually lives in Wilton, with the trucks running out of the Galt headquarters about sixteen minutes away. Call (916) 919-7642. Search for a carpet cleaner in Wilton and most results are national franchises dispatching a van from Sacramento or lead-generation pages listing twenty towns with an address in none of them. This is the local one.
Why does my Wilton carpet get so dirty on a rural property?
Wilton properties sit on larger lots with gravel or dirt driveways, outdoor animals, and doors that open more or less directly onto the outdoors — so far more dry particulate walks in than in a suburban house. On top of that, valley oak and blue oak push heavy pollen in spring and drop fine litter year-round, and homes along the Cosumnes River corridor take on fine river silt that travels deep into the house. Thorough dry soil removal before any moisture is the step that matters most, and it is the step most cleaners rush.
Why does my carpet stop vacuuming clean in the winter in Wilton?
Wilton’s wet season tracks moisture indoors on boots and paws for months, and damp soil behaves differently than dry soil — it binds to the fiber instead of sitting loose in the pile, which is why the vacuum stops pulling it out by January. That is exactly where hot water extraction (commonly called steam cleaning) beats the low-moisture methods the franchises push: the rinse releases the bound soil and the vacuum takes the water back out, so the carpet is not left damp on top of everything else.
Is pet urine worse on Wilton properties?
It is more common here than anywhere we serve, simply because more Wilton households have more animals with more access — larger dogs, dog doors, indoor-outdoor freedom. That raises the odds contamination has reached the pad rather than sitting on the carpet face. We map it with a UV inspection first, treat what the light shows, and say plainly when it has gone deeper than cleaning reaches. We never guarantee a result on pet urine.
Does well water affect cleaning in Wilton?
Many Wilton properties run on wells, and hard well water leaves mineral residue that changes how grout looks, how it responds to cleaning, and what sealer will hold. It is worth factoring into how often tile realistically needs attention — we will give you an honest interval rather than selling you a schedule.
Carpet cleaning in Herald, California
Herald gets listed more often than it gets served. Spiker has been on the actual route through Herald since 2013 — roughly eleven minutes from the Galt headquarters, one of the closest communities we serve. Here is what Herald homeowners ask, answered for Herald.
Does anyone actually come out to Herald for carpet cleaning?
Yes — Spiker has been on the real route through Herald since 2013, and at roughly eleven minutes from the Galt headquarters it is one of the closest communities we serve. Most weeks we have a morning open within a few days. Call (916) 919-7642. Most of what surfaces in a search for a Herald carpet cleaner is a company in another city that added Herald to a coverage map. Being inside a shaded circle on a map is a different thing from having driven the route for over a decade.
Why does my Herald carpet take on so much dirt?
Herald is rural — larger properties, more outdoor traffic coming in, more animals, and a heavier dry soil load than anywhere suburban. Because so many Herald homes have direct outdoor access with no entry buffer, the single highest-value thing most owners can do is entry matting: it captures soil before it walks onto the carpet and extends the life of the flooring more than any cleaning schedule does. Vacuuming before we arrive genuinely helps here too, and we will tell you that rather than pretend it makes no difference.
How is pet urine different on Herald acreage?
On acreage, an animal with a dog door and open ground comes and goes all day, so contamination tends to spread wide and thin rather than concentrate where a single accident would — and wide-and-thin is the kind you can smell without ever finding. We map it with UV first, treat what the light shows, and say plainly when it has gone deeper than cleaning reaches. We never guarantee a result on pet urine.
Do wells and septic affect cleaning in Herald?
Many Herald properties run on wells and septic. Hard water affects both grout appearance and sealer performance, and it is worth factoring into how often tile realistically needs attention. We give you an honest interval for your actual water, not a one-size schedule.
