Wash your car in winter on a dry day that stays above freezing until the car is dry. Pre-wash with a snow foam such as Autobead Snow Foam to loosen road salt, wash with a soft mitt, then dry the paint, door shuts and seals fully. If it is freezing, wait or use a waterless wash under cover. See our winter and Christmas page.
How cold is too cold to wash a car?
If water will freeze on the paint, in the door seals or on the ground before the car is dry, it is too cold. Water left in seals and locks can freeze them shut, and water on the drive turns to ice where you stand. On those days we wait for a milder spell, or clean the car under cover with a waterless wash.
Why wash your car in winter at all?
Gritted roads leave salt and grit on the paint, the wheels, the sills and the underside, and wet roads add a film of traffic grime. Left for weeks it builds up and is harder to shift, so a wash on the next mild day does more good than one big clean in spring. Protecting the car before the worst weather makes each wash easier, as our guide to protecting a car in winter explains.
How do you wash a car in cold weather, step by step?
The order is the same as any safe wash, with more time on the salty lower half and more care drying.
- Pick the moment: a dry day, above freezing, with time for the car to dry before the temperature drops.
- Wheels and arches first: they hold the most salt and grit, so clean them before the paint.
- Rinse, then snow foam: rinse off loose salt and grit first. Mix Autobead Snow Foam 1 part to 4 parts water in a foam lance bottle, cover the car from the bottom up, leave it for up to 10 minutes without letting it dry, and rinse from the top down. Rinse the sills, arches and the underside well.
- Contact wash: use the two bucket method and a soft mitt, working from the roof down.
- Rinse and dry: dry the paint and glass with a large drying towel, then open every door, the boot and the fuel flap and dry the shuts and seals.
- Protect: on a dry day before the worst weather, a spray sealant on clean, dry paint and wheels makes the next wash easier.
Which products do we use for a winter wash?
A snow foam, a soft mitt, a large drying towel and a sealant cover the whole wash.
A concentrated, mild alkaline pre-wash that removes traffic film and dirt before the contact wash and will not degrade your protection at the correct dilution of 1 part to 4 parts water.

What if there is no hose or it is too cold outside?
A waterless or rinseless wash cleans light winter grime without a hose, which suits a garage or a car park. It is not for a car caked in mud and salt: rinse that off on a milder day first. Our waterless wash guide covers the technique.
For winter dirt and salt, use it as a rinseless bucket wash only, 50ml in 10L of cold water. Pre-spray each panel first with it diluted 50:1, wait 1 minute, then wash one panel at a time in straight lines without pressure and dry with a clean microfibre. Avoid it on an excessively dirty car.

Common questions
Can I use warm water to wash my car in winter?
Lukewarm water in the wash bucket is fine on a car that is not frozen, and kinder on your hands. Never pour hot or lukewarm water on frozen glass: a sudden change in temperature can crack it. If there is ice on the car it is too cold to wash it. Our de-icing guide explains the safe way to clear ice.
How do I stop the doors freezing shut after a wash?
Dry the door shuts and rubber seals with a clean towel before you close up. Our door shuts guide shows where water hides.
How often should I wash my car in winter?
Whenever the roads have been gritted and the weather gives you a dry spell above freezing. Regular light washes stop salt and grime building up.
