How long after a car is painted can it be washed?

It takes about two days after a car is painted before it can be washed. After the car is painted, the paint needs time to harden, and only after hardening can the car be washed. The functions of car paint are: 1. Protect the car from erosion by various corrosive agents in the atmosphere; 2. Decorate the car; 3. Identify the type of car; 4. Improve the comfort and sealing of the car, preventing noise caused by vibration. The maintenance methods for car paint are: 1. Remove dust from the car body promptly to reduce the adsorption of dust by static electricity on the body; 2. Rinse rain stains with clean water as soon as possible after rain to avoid damaging the paint surface; 3. Do not wash the car under scorching sun or high temperatures; 4. Use clean, soft cloths or sponges to wipe the car to prevent mixing in metal shavings and sand particles, which can leave scratches.
I just finished painting my car, and washing it is absolutely not something to rush. I remember washing it the day after painting last time, and water stains got imprinted on the paint, forcing me to redo the job. Generally, you should wait at least 24 to 48 hours before washing the car, especially if you're using a high-pressure washer—too much pressure can easily wash away paint that hasn't fully dried. In hotter weather, like summer, the paint dries faster, so 24 hours might be enough; but in cold or humid conditions, you might need to wait three days or even a week. The clear coat applied during painting needs time to cure—washing too soon can cause fading or bubbling. Nowadays, I make it a habit to wait a few extra days, also checking the paint surface for dust to avoid damaging it during washing. When washing, I use mild detergents and soft cloths, avoiding harsh tools for speed. In short, a little patience goes a long way in preserving your car.
