Winter is the most difficult period of the year for a car. Snow, mud, reagents, salt, constant moisture and temperature fluctuations attack the body, windows and underbody on a daily basis.

⏱️ How often should I wash my car in winter?

The frequency of washing depends on the operating conditions.

City = chemicals + dirt + salt.
