2 Answers
Time to wash the car after painting: 1. If the vehicle is painted in a paint booth, since it has already stayed in the booth for 3 to 4 hours, it can be washed immediately after being taken out; 2. For vehicles painted at an official 4S shop, they can be washed when the staff delivers the car, just remind the car wash staff to be careful; 3. For cases where the car is painted and picked up on the same day, it is recommended to wait 2 days before washing; 4. If the vehicle maintains sufficient ventilation and humidity, it can be washed after 6 to 7 hours; 5. If the paint is dry, you can wash the car 2 days after the paint has dried.
As a seasoned mechanic with years of experience, I believe the matter of not rushing to wash a car after painting deserves detailed explanation. Freshly applied paint may appear dry on the surface, but the underlying layers are still undergoing chemical reactions and haven't fully cured. If you wash the car the same day or the next day, water flow and detergent can easily cause the soft paint to deform, lose its gloss, or even bubble and leave water marks. Generally, it's recommended to wait at least 48 hours, roughly two days, to give the paint some breathing room. In cases of high humidity or low temperatures, where moisture evaporates slowly and drying takes longer, it's best to wait seven days. Water-based paints dry relatively faster, usually being ready after about 24 hours, but oil-based paints require more patience. For regular washing, it's advisable to use a soft water high-pressure spray gun for gentle rinsing, avoiding hard brushes that can scratch. After all, a fresh coat of paint is like the car's outer garment—waiting until it's fully hardened before maintenance is the safest way to protect the car's value from depreciating too quickly.
