Interior Care
The Best All-Purpose Cleaner for Cars in 2026
An all-purpose cleaner is a concentrate, and the dilution decides whether it is an engine degreaser or a seat cleaner. Three of these five never say what that dilution is.

The dilution is the product
An all-purpose cleaner is sold strong so that one bottle can do everything, and water is how you turn it down. The concentrate that lifts grease from a fender well will stain a delicate surface at full strength, which is why the ratio is the most important number an APC maker can publish.
Two makers here publish one. Gtechniq state W5 goes on neat for serious messes or diluted 10:1 for lighter cleaning, and Meguiar’s publish both ends for D101: 4:1 for heavy-duty work like tires, engine bays and badly soiled upholstery, 10:1 for general interior cleaning. Adam’s say theirs is gentle enough for body panels, interior components and even leather when diluted, without saying by how much. 3D say theirs can be diluted to best fit the job, and Chemical Guys say to dilute All Clean+ to clean various surfaces.
| Cleaner | Sizes | Published dilution | Cheapest per oz | Stated surfaces |
|---|---|---|---|---|
| Gtechniq W5 | 500ml / 1 liter / 5 liters | Neat, or 10:1 for lighter cleaning | $0.30 | Engine bays, wheel wells, carpets, interior fabrics |
| Meguiar's Professional D101 | 1 gallon / 5 gallons | 4:1 heavy-duty, 10:1 light-duty | $0.16 | Carpets, upholstery, vinyl, fabric, rubber, plastic, tires, engine bays |
| Adam's All Purpose Cleaner | 16 oz / gallon / 5 gallons | Not published | $0.27 | Body panels, interiors, leather when diluted, and thirteen more named |
| 3D All Purpose Cleaner | 16 oz / gallon | Not published | $0.27 | Leather, vinyl, rubber, plastic, cloth seats, door panels |
| Chemical Guys All Clean+ | 16 oz / gallon | Not published | $0.41 | Plastic, vinyl, carpets |
Strong enough for an engine is too strong for a dashboard
Meguiar’s are the most explicit about strength, and they do it with numbers: 4:1 for tires, engine bays and heavily soiled upholstery, 10:1 for carpets, upholstery and vinyl inside the car. Two ratios and the jobs they belong to is the most useful thing any maker on this page publishes.
Adam’s publish the most careful instruction: rinse and dry immediately, and on a delicate surface follow with a microfiber towel dampened with water to avoid staining. An APC left to dry is how it stains, whichever bottle it came from. For screens, piano black and soft-touch dashboards, a dedicated interior cleaner is the safer tool.
Only one maker addresses your wax
Gtechniq state W5 is safe for sealants, waxes, trim and chrome and cleans without stripping protection. None of the other four addresses protection at all, which matters on a waxed or coated car: a cleaner strong enough to degrease can be strong enough to shorten a wax.
3D’s enzyme is aimed at a different mess
3D state their cleaner contains an enzyme that removes biological and organic stains and their odors, alongside inorganic stains such as make-up, motor oil, grease and tar. That makes it the one here aimed at the back seat after children or dogs rather than the engine bay. Removing odors from a car covers the rest of that job.
What to buy
- The only published dilution, and cheap to try: Gtechniq W5, $7.95 for 500ml.
- Volume, with both ratios published: Meguiar's Professional D101, $19.95 a gallon.
- The longest surface list, from exhaust tips to canvas tops: Adam's All Purpose Cleaner, $12.99 for 16 oz.
- Organic stains and the smells that come with them: 3D All Purpose Cleaner, with its enzyme.
- Engine bays specifically: a degreaser sold for the job, compared in the engine bay roundup.
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 pickThe only all-purpose cleaner here with a published dilution
Gtechniq W5 Citrus All-Purpose Cleaner
Gtechniq
$7.95 for 500ml, biodegradable and citrus-based, and Gtechniq publish how to use it: neat for heavy soiling or diluted 10:1 for lighter jobs. That ratio is the figure an all-purpose cleaner most needs, and nobody else on this page gives one.
- Sizes
- 500ml ($7.95), 1 liter ($13.95), 5 liters ($49.95)
- Dilution
- Neat for heavy soiling; 10:1 for lighter cleaning
- Chemistry
- Biodegradable, citrus-based
- Stated surfaces
- Engine bays, wheel wells, carpets, interior fabrics
- pH
- Not published
What it does well
- Dilution published: 10:1 for lighter cleaning
- Stated safe on sealants, waxes, trim and chrome
- Biodegradable citrus chemistry stated
- Rated from engine bays and wheel wells to carpets and fabrics
- 5 liters for $49.95 is 30 cents an ounce
Who it is not for
- One dilution published, not a range by task
- No pH published
- Gtechniq's own site sits behind a bot challenge; figures from an authorized retailer
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 ounce10.0/10, weight 16%
- $7.95 for 16.9 oz works out at $0.47 an ounce, scored against a band of $0.60 (good) to $2.00 (expensive) for a interior cleaner.
- Price against the ceiling7.7/10, weight 14%
- A listed $7.95 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
- Gtechniq 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.
- Spec transparency8.0/10, weight 18%
- 4 of the 5 specifications we went looking for are published by Gtechniq. Every blank row below is something the maker will not put in writing, and it costs the product points here.

2The only concentrate here that publishes both of its ratios
Meguiar's Professional D101 All Purpose Cleaner
Meguiar's
A gallon of professional dilutable APC at $19.95, with the two numbers this category usually withholds printed on the listing: 4:1 for heavy-duty work like tires, engine bays and badly soiled upholstery, and 10:1 for general interior cleaning. That is one more published figure than any other gallon on this page offers.
- SKU
- D10101 (1 gallon); D10105 (5 gallon)
- Published dilution
- 4:1 for heavy-duty cleaning; 10:1 for light-duty interior cleaning
- Stated surfaces
- Carpets, upholstery, vinyl, fabric, rubber, plastic, tires, engine bays
- Action
- Foaming, stated to lift dirt and grime
- Stated caution
- Test on an inconspicuous area before use
- pH
- Not published
- Effect on wax or sealant
- Not published
What it does well
- Both dilution ratios published: 4:1 heavy-duty, 10:1 light-duty
- $19.95 a gallon is about 16 cents an ounce before dilution, the cheapest here by volume
- Interior and exterior surfaces named: fabric, vinyl, rubber, plastic, carpets, upholstery, tires and engine bays
- Foaming action stated, which is what keeps a cleaner on a vertical surface long enough to work
- Sold as a gallon (D10101) and a 5 gallon (D10105), so a heavy user is not rebuying bottles
Who it is not for
- No pH published, like every other cleaner on this page
- Meguiar's own site could not be reached to verify these figures first-hand; they come from an authorized retailer republishing the maker's SKU and ratios
- Nothing published about protection: whether it strips a wax or a sealant is not addressed
- Gallon-only by the time it is this cheap, so a trial costs twenty dollars
- The retailer tells you to test it on an inconspicuous area first, which is the honest version of "safe on everything"
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.
