Detailing has a marketing problem. Search for advice and you will find forty-step processes, bottles that cost more than a service, and videos filmed in showrooms so clean they look computer-generated. The result is that most people do nothing, and then pay for a machine polish when the paint is already tired.
The truth is less glamorous. Paint survives on a small number of habits repeated often: keep it clean, keep it covered, and never drag dirt across the surface. Everything else is refinement.
Understand what you are protecting
Modern paint is a thin, hard layer of colour under a thinner clear coat. The clear coat is what gives gloss, and it is what scratches. Every swirl mark you see in sunlight is a small amount of clear coat removed by grit that was trapped somewhere it should not have been, usually a sponge, a brush or a dry towel.
So the goal is not to polish more. The goal is to remove less. A car washed gently for ten years will have better paint than a car machine-polished twice a year and washed carelessly in between.
The fortnightly wash
Work in shade on cool paint, and start at the top. Roof, glass, bonnet, then down the sides, then the sills and wheels last with a separate bucket. Two buckets, one for soap and one for rinsing the mitt, is the whole trick. Grit guards help, but the discipline matters more than the accessory.
Dry with a large microfibre towel laid flat and pulled, not scrubbed. If the car is still wet after one pass, reach for a second towel rather than pressing harder. Water left to dry in the sun leaves mineral spots that etch into clear coat over time.
Products worth owning
- A pH-neutral shampoo. Aggressive cleaners strip protection and dry trim; a gentle one does the job with far less risk.
- Two wash mitts and two buckets. One for paint, one for wheels, never swapped.
- A large drying towel and a smaller one for door shuts. Door shuts are where water sits and corrosion begins.
- A spray sealant or wax. Two applications a year is enough for most cars and makes every subsequent wash easier.
- A dedicated wheel cleaner and a soft brush. Brake dust is acidic and bonds to lacquer if left for weeks.
What to skip
You do not need a foam cannon to have clean paint, although it helps. You do not need a machine polisher unless you are correcting existing defects, and correcting them yourself without practice usually makes things worse. You certainly do not need to clay a car more than once a year; clay removes contamination and a little clear coat with it.
Interior care follows the same logic. Vacuum often, wipe surfaces with a damp microfibre, and use a dedicated cleaner on leather every few months rather than a generic shine product that attracts dust. The auto detailing reference on Wikipedia is a surprisingly good primer on what each stage is actually for.
When to call a professional
Deep scratches, oxidised single-stage paint, faded plastic trim and paint transfer from a car park scrape are jobs for someone with a gauge, a polisher and insurance. A good detailer will also tell you when a panel is beyond correction. That honesty is worth paying for.
If the routine above sounds like a lot, start with just the two-bucket wash and a spray sealant. That alone puts you ahead of most cars on the road. And if you are about to spend money on a car worth protecting, our guide to buying a classic without buying a money pit is the more important read.
