What is the method for removing water stains from a car roof?

Use toothpaste to clean the car body. Apply an appropriate amount of toothpaste to the water stain area, then wipe with a soft towel. Repeat several times and rinse with water. Purchase a clay bar. After washing the car next time, dry it thoroughly; this can also remove tar spots. Dishwashing liquid can also remove stubborn water stains. Apply an appropriate amount to the stained area, gently rub with your fingers, then wipe with a dish-scrubbing sponge, rinse with water, and repeat several times. Dilute hydrochloric acid with water in a plastic container, scrub with a plastic brush, then rinse with water. If some water stains remain, wipe a few more times and rinse with water. Use fine-grit polishing compound to polish the car's surface. This won't damage the paint because there is a thin layer of clear coat protection. After polishing, apply wax to prevent water stains from adhering.
My car's ceiling also had water stains before, which were caused by rain leakage due to poor window sealing. I first parked the car, opened the windows to allow air circulation, and used a dry towel to absorb as much moisture as possible. After it was mostly dry, I took out an interior cleaner, sprayed it a few times on the stained area, and then gently wiped off the stains with a clean soft cloth. If the stains were deep or had an odor, I occasionally used a solution of white vinegar mixed with water, which worked well after wiping, but I was careful not to use too much to avoid leaving a sour smell. After finishing, I also checked around the car ceiling to ensure there were no other leaks, reducing the chance of future issues. When parking, I try to choose dry places to prevent moisture buildup.
When I find water stains on the car roof, I usually identify the cause first, which is often due to water leakage during rainy days or car washing. My DIY approach is simple: prepare a damp cloth and a vacuum cleaner. First, use the vacuum to remove dust and loose dirt, then gently wipe the stain with the damp cloth dipped in a mild detergent solution. After a few minutes, wipe it clean with a dry cloth. For stubborn stains, I mix a little baking soda with warm water and wipe again. Be careful not to scrub too hard to avoid damaging the roof fabric. Afterwards, I place a dehumidifier box in the car to prevent moisture from causing new water stains.
