Key takeaways
- Road salt and grit are the main winter threat to paint, wheels and the underside of the car.
- Put protection on the paint in autumn, while it is still mild enough to work outside.
- Through the winter, a touch-free pre-wash does most of the work before the mitt goes near the paint.
The first gritting lorries usually appear before most of us have thought about winter. From then until spring, the car is coated in a mix of salt, grit and wet road film on almost every journey. None of it does serious harm in a week, but left for months it dulls the paint, pits the wheels and makes the glass harder to see through on dark mornings. An hour or two of preparation in autumn makes the whole season easier.
Why winter is hard on a car
Salt keeps the roads safe, and it also speeds up corrosion wherever it sits on bare or chipped metal. Mixed with grit and spray, it forms a grey film that clings to the lower doors, the sills and the wheels. Because the days are short and cold, the car gets washed less often, so that film stays on for longer than it would in summer.
Glass suffers too. Low sun, wet roads and the heater running on a damp interior leave a greasy haze on the inside of the windscreen, which shows up the moment headlights come towards you.
Four jobs to do before the cold arrives
| Job | Why it matters in winter | What to use |
|---|---|---|
| Deep clean the paint | Protection only bonds well to clean paint | Pre-wash, then a two-bucket wash |
| Add protection | Salt and road film rinse off a protected surface far more easily | Ceramic Hydro Wax after the wash |
| Clean the glass inside and out | Haze on the inside of the screen causes glare at night | Glass Cleaner and a glass microfibre |
| Clean the wheels properly | Brake dust and salt sit on wheels all winter | A dedicated wheel cleaner and a separate brush |
Start with a thorough wash. If you have not tried it yet, our guide to the two-bucket method shows how to do it without adding swirl marks. Once the paint is clean and dry, top up the protection. Ceramic Hydro Wax is a concentrated hydro wax that works on all paint colours and is safe over wax or coatings you have already applied, which makes it a quick job after a wash. If you want something that lasts for years instead of months, read what a ceramic coating is and whether it is worth it.
Pro tip: do the inside of the windscreen last, with a clean cloth kept only for glass. Spray Glass Cleaner onto the cloth, wipe, then dry with a second cloth. It is the single job that makes the biggest difference to night driving.
A simple wash routine for the salty months
In winter the car is dirtier, so the touch-free stage matters more. The aim is to get as much salt and film off as possible before anything touches the paint.
- Rinse the lower half first. Pay attention to the wheel arches, sills and the area behind each wheel, where salt collects.
- Apply a pre-wash. Neutral Snow Foam is pH neutral and safe on wax and coatings. For heavier road film, Traffic Film Remover is an alkaline pre-wash you dilute to suit how dirty the car is.
- Let it dwell, then rinse. Give it a few minutes to soften the dirt, without letting it dry, and rinse thoroughly.
- Finish with a contact wash when you can. On a mild day, follow with a two-bucket wash. On a freezing one, the pre-wash and rinse alone are far better than leaving the salt on.
On a waxed or coated car, keep Traffic Film Remover weak. The label advises a mix weaker than 1:20 on protected paint, because stronger mixes can take wax off.
Frequently asked questions
How often should I wash my car in winter?
More often than in summer if you can. Every week or two is a sensible aim while the roads are being gritted, even if some of those are just a pre-wash and rinse.
Is it safe to wash a car when it is freezing?
It is better to wait for a day above freezing. Water can freeze on the paint, in door seals and in locks. If you do wash, dry the door shuts and seals afterwards.
Will snow foam remove my wax?
Neutral Snow Foam is pH neutral and safe on wax and ceramic coatings, so it cleans without stripping the protection you put on in autumn.
