2 Answers
Twelve methods to remove stubborn stains from car glass: 1. Toothpaste for water stains: Apply toothpaste to the car body, take an appropriate amount, apply it on the water stains, and then wipe with a soft towel. 2. Sludge remover for water stains: Purchase a sludge remover, which can also remove asphalt spots when the car is dry during the next wash. 3. Computer screen cleaning kits have a good cleaning effect on simple stains. 4. Detergent for water stains: Dishwashing detergent used in the kitchen can also remove stubborn water stains. 5. Car glass cleaner for stains: Especially effective against stains caused by insect remains, bird droppings, and resin, with the same usage method as detergent. 6. Hydrochloric acid for water stains: Buy some hydrochloric acid, dilute it in a plastic container, and use a plastic brush. After a while, it can be removed with water. If some stains remain, wipe again with diluted hydrochloric acid and rinse with clean water. 7. Matte polish + waxing: At car paint repair points, use fine polishing compounds to polish the car body surface without damaging the paint, as there is a thin layer of varnish outside, like a transparent plastic layer. After waxing, it won’t get stained by water. 8. Avoid using gasoline: Gasoline is a highly soluble liquid that dissolves water stains and the paint surface. 9. Professional body water stain remover: For substances like asphalt, clean dirt and sand from the car body before use, pour the remover on a sponge, wipe off the water stains, and then rinse with clean water. 10. Polishing and respraying: If the wax film cannot be removed from the defective area, smooth it gently and then polish.
Over the years, I've developed a simple method for dealing with stubborn stains like raindrops or resin marks when washing my car. First, rinse the glass with a soft hose to wet it—never wipe it dry to avoid scratches. Then, apply household white vinegar and let it sit for five to ten minutes to soften the stain. Alternatively, make a paste of baking soda and water, gently apply it to the spot, and rub in circles with a sponge. For tougher stains, buy a professional car glass cleaner from the supermarket, spray it on, and wipe dry with a clean cloth. Avoid scrubbing too hard to prevent damaging the glass surface. When parking, try to avoid tree sap and bird droppings. After washing, applying wax can help prevent stain buildup.
