Wash and Decontamination
How to Clean Wheel Wells
The dirtiest part of any car is the part nobody cleans. Wheel wells hold packed brine and grit against metal, and they take ten minutes a corner to put right.

Why it matters more than it looks
A wheel well is a trap. Slush, salt and grit get thrown in, pack behind the liner, and stay damp long after the outside of the car has dried. That is the corner of a car where corrosion starts, and it is also where a surprising amount of road noise comes from once packed debris starts resonating.
There is a cosmetic argument too. Clean wheels against a brown, crusted arch look unfinished, and the arch is in every photograph of the car taken from the side.
Do it first, not last
Wheel wells come before wheels, and wheels come before paint. Everything you loosen in an arch runs down over the wheel and out onto the lower panels, so cleaning in the other order means doing the wheels twice. Rinse the arch out before any chemical goes on, because most of what is in there is loose.
The chemistry, with the dilution published
This is an all-purpose cleaner job, not a wheel cleaner job. Wheel cleaners are formulated for brake dust on a finished surface; an arch liner is unfinished plastic with mud on it.
Gtechniq’s W5 Citrus All-Purpose Cleaner is $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 published ratio is rarer than it should be in this category. Adam’s All Purpose Cleaner is $12.99 for 16 oz, a concentrate Adam’s describe as strong enough at full strength for grease and gentle enough diluted for body panels and interiors; they do not publish a ratio. The APC roundup compares the field.
The brush is the whole tool list
A long-handled, soft-bristled brush reaches the top of the arch where the packed grit sits. The Hi-Tech 10 inch flow-thru brush is $11.99 for a 10-inch foam block with 2.5-inch super-soft flagged-tip nylon bristles that 3D state resist acids and detergents, plus a protective bumper. The handle is a standard screw fitting and is not included, which is the detail to catch before you order.
For the tight corner behind the liner, a wheel woolie or a long, narrow brush from the wheel brush roundup gets where a flat brush cannot.
Should you dress the liner?
A dressed arch looks finished and sheds water better, but a greasy dressing slung onto a wet road collects dust and ends up on the paint above it. A water-based, satin product is the right choice. Adam’s Rubber Mat & Liner Protectant is $16.99 for 16 oz, water based with cross-linking acrylic polymers, and Adam’s say it dries to a darkened satin finish that is never slippery or greasy, even wet.
Spray it on a dry liner, let it soak, wipe the excess, and let it cure before driving. If you would rather not dress at all, a clean liner still looks a great deal better than a packed one, and winter washing covers why keeping them clear matters most in the salted months.
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.

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.

- Dilution
- Neat for heavy soiling; 10:1 for lighter cleaning

What it does well
- Dilution published: 10:1 for lighter cleaning
- Stated safe on sealants, waxes, trim and chrome
- Biodegradable citrus chemistry stated

How this score was calculated
