Most wasted effort in car cleaning comes from doing things in the wrong order and then having to redo them. The sequence below is not fussiness — each step is there because getting it wrong means going back over work you have already done.
The order
- Interior first. Vacuum and wipe down before you touch the outside.
- Wheels and arches. Always before the bodywork.
- Pre-wash. Snow foam or TFR, depending on how dirty the car is.
- Rinse.
- Contact wash. Two buckets, top down.
- Decontamination, if needed. Iron fallout remover, tar remover, clay.
- Final rinse.
- Dry.
- Glass.
- Protection. Wax, sealant or a spray protectant.
- Tyres and trim. Dressings last.
Why interior comes first
Two reasons. You will open doors, kick the sills and lean on panels while doing the interior — all of which puts marks on clean paint. And vacuuming throws dust into the air that settles on a wet car.
Doing the inside first also means that if you run out of time or the weather turns, you have finished the part that does not depend on it.
Why wheels come before paint
Wheel cleaners are the harshest products in a normal wash, and wheels carry the heaviest, most abrasive contamination on the car. Splashing that onto clean paint, or worse onto dry paint, is asking for trouble. Do them first, rinse well, then move on.
Use separate buckets, mitts and brushes for wheels and never let them near your paintwork. Brake dust embedded in a wash mitt is sandpaper.
Why protection comes after glass
Glass cleaners are usually alcohol-based and will happily remove a fresh wax or sealant if they overspray onto the paint. Do the glass while the paint is still bare, then protect.
Why dressings come last
Tyre and trim dressings sling, run and transfer. Applied before the final wipe-down, they end up on your paint and in your microfibres. Applied last, on a dry tyre, they stay where they belong.
The one that catches everyone out
Decontamination — iron remover, tar remover, clay — strips protection. If you clay a car and then skip straight to drying and putting it away, you have left the paint completely bare. Decontamination and protection go together in the same session, always.
A shorter version for a maintenance wash
Not every wash needs all eleven steps. A maintenance wash on a protected car is: interior, wheels, pre-wash, rinse, contact wash, rinse, dry, glass, quick detailer. Fifteen minutes if the car is not far gone.
Products for each stage are grouped by job in our shop, and Fast Lane will build a kit for the order above if you would rather not pick them yourself.
Before you start
Always read the label on the product you are using and follow the instructions on it for dilution, application and safety. Work in the shade on cool paint, and test anything new on a small, hidden area first — particularly on trim, wraps and finishes you are not familiar with.
