The honest answer about carpet
Carpet is a deeper problem than upholstery because there is more of it, it holds more, and the soiling has usually been ground in by feet. Spraying a cleaner and wiping it off cleans the top of the pile and leaves the rest, which is why a carpet looks better for a day and then looks the same again.
What removes soiling from carpet is agitation plus extraction: something to break the bond between the dirt and the fiber, and something to physically pull the resulting slurry out. Both halves are necessary and the second one is the half people skip.
| Approach | What it needs | Cost | How good |
|---|---|---|---|
| Spray, agitate, blot | Cleaner, brush, dry towels | About $15 | Fine for light soiling, poor on ground-in dirt |
| Spray, agitate, wet vacuum | Cleaner, brush, shop vacuum | About $15 plus a vacuum you may own | Good; the sensible answer for most people |
| Low-foaming chemical plus extractor | Extractor shampoo and a machine | $799.99 upwards for the machine | The only method that removes soiling from the backing |
Match the chemical to the method
This is the part people get wrong. Adam’s Extractor Shampoo is stated low-foaming because an extractor needs it to be — foam displaces the volume in the recovery tank and stops the machine working. Chemical Guys Foaming Citrus is high-foaming because a hand clean needs it to be.
Using each in the other’s method produces a bad result and people blame the chemical. Read the foam behavior before you buy, and if it is not stated, assume it foams.
Take the mats out and do them separately
Floor mats absorb the great majority of what comes into a car on shoes, and they can be removed, cleaned aggressively and dried in the sun in a way fixed carpet cannot. Doing the mats properly and the carpet lightly gets you most of the visible result for a fraction of the effort.
It also protects the carpet underneath. A car with good rubber mats has carpet that stays near-new, which is worth more than any cleaning product on this page.
If you are going to buy an extractor
Adam’s non-heated unit publishes a 3 gallon tank capacity and notes that warm water can be added to the reservoir, which is their own stated workaround for the absence of a heater. It publishes no vacuum lift and no pump pressure, which are the two figures that describe what an extractor actually does.
At $799.99 that is a lot of unpublished specification. The case for buying one is that you detail other people’s cars, or you have a genuinely wrecked interior and renting is not available. For a personal car, a wet vacuum and a brush is the right answer and the difference is smaller than the price gap suggests.
Every pick, with the working
Each entry lists the specifications the maker publishes, the axis scores those specifications produce, and what you give up. Rows that read “Not published” are not omissions on our side: they are figures the maker will not commit to in writing, and they cost the product points on the transparency axis.
Our pickFoam that lifts rather than soaks
Chemical Guys Foaming Citrus Fabric Clean
Chemical Guys
$9.99 ready to use or $11.99 as a concentrate, in a foaming format designed to be agitated with a brush. Foam is the right delivery for upholstery because it puts cleaner on the fiber without saturating the foam underneath it.
- Formats
- Concentrate 16oz / 32oz / gallon; ready-to-use 16oz
- Delivery
- Foaming
- Stated method
- Apply foam, agitate with a brush
- Dilution ratio
- Not published
- pH
- Not published
- Extractor safe
- Not published
What it does well
- Foaming action means less water into the seat base, which is what causes lingering smell
- Ready-to-use and concentrate versions of the same chemistry
- Explicit instruction to agitate with a brush, which is the step people skip
Who it is not for
- No dilution published for the concentrate
- No pH figure published
- Citrus fragrance is strong and stays for days
How this score was calculated
- Protection claimdropped
- Nothing in this category is bought on how long it lasts, so the axis is dropped and the other weights are re-normalized.
- Capabilitydropped
- No single published number decides capability in this category, so the axis is dropped rather than invented.
- Cost per ounce9.1/10, weight 16%
- $11.99 for 16 oz works out at $0.75 an ounce, scored against a band of $0.60 (good) to $2.20 (expensive) for a upholstery cleaner.
- Price against the ceiling6.6/10, weight 14%
- A listed $11.99 against the $35 one upgrade in this category realistically tops out at. A list price captured on the compile date, not a live price and not what you will pay.
- Written commitmentdropped
- Chemical Guys publishes no warranty term on this product's own page, so the axis is dropped. On a tool that is worth noticing, and it costs the product points on transparency instead.

2Machine extraction, where foam is the enemy
Adam's Extractor Shampoo
Adam's Polishes
16oz at $9.99 or a gallon at $39.99, a highly concentrated low-foaming detergent with orange oils for grease. Low-foaming is the specification: a normal upholstery shampoo in an extractor fills the recovery tank with foam and stops working.

3Deep cleaning cloth seats and carpet
Adam's Proline FIBER Fabric and Upholstery Cleaner
Adam's Polishes
$29.99 for 24oz of concentrate from Adam's trade line, aimed at cloth upholstery, carpets and fabric components. It is a concentrate sold without a published dilution, which is the single most useful number a concentrate could carry.

4Actually removing what is in the carpet
Adam's Non-Heated Carpet Extractor
Adam's Polishes
Skip this one. $799.99, which is more than every chemical on this site combined, and it publishes no vacuum lift and no pump pressure. It is genuinely the tool that removes soiling rather than redistributing it, and almost nobody detailing their own car should buy one.
$799.99 for a 3 gallon non-heated extractor built with Sandia. An extractor is the only tool here that removes the dirt rather than redistributing it, and Adam's notes you can fill the reservoir with warm water to close most of the gap to a heated unit.
- Tank capacity
- 3 gallons of water and solution
- Heating
- None; warm water may be added to the reservoir
- Built with
- Sandia
- Vacuum lift
- Not published
- Pump pressure
- Not published
- Weight
- Not published
- Warranty
- Not published
What it does well
- 3 gallon capacity published
- Warm water in the reservoir is Adam's own stated workaround for the lack of a heater
- Built with Sandia, a named manufacturer, rather than an unbranded import
Who it is not for
- $799.99 is more than every chemical on this site combined
- No vacuum lift or pump pressure published
- Non-heated, and heat genuinely helps on old stains
How this score was calculated
- Protection claimdropped
- Nothing in this category is bought on how long it lasts, so the axis is dropped and the other weights are re-normalized.
- Published tank capacity5.0/10, weight 22%
