What to Do with Colorful Stains on Car Glass?

It's best to gently wipe the dust off car glass, using a slightly damp cloth rather than a very wet one, as dust particles can cause minor scratches on the car glass surface. After removing surface dust from car glass, there are usually stubborn spot stains that should be wiped with a cleaning liquid. When cleaning grease, you can use a specialized grease cleaner. Adding a small amount of ammonia to the water can make the car glass more transparent. It is recommended to use a specialized glass cleaner for washing car glass, as it cleans better. Avoid using highly corrosive cleaners.
There are colorful stains on the glass, likely caused by water residue or grease left behind during car washing. I’ve encountered this issue frequently before. First, spray a solution of warm water with a few drops of dish soap onto the glass, then wipe it clean with a soft cloth or microfiber towel. If that doesn’t work, spray a mixture of white vinegar and water (1:1 ratio), let it soak for five minutes, and then wipe it off. Don’t forget to check the wiper blades—aged or dirty rubber strips can also leave colored streaks. Replacing the wipers usually solves most of the problems. Regularly maintain the glass with a glass cleaner, and avoid washing the car under direct sunlight, as rapid water evaporation can leave more stains. The key to prevention is thoroughly drying the glass surface after each wash—this minimizes stain buildup and ensures much clearer visibility while driving.
The colored spots on the car windshield are quite annoying, mostly caused by hard water stains or chemical residues. I suggest wetting the glass with soapy water, waiting for it to soften, and then scrubbing with a cloth. For stubborn spots, you can apply a bit of baking soda paste or lemon juice, let it sit for a few minutes, and then scrape it off. The cause is often poor-quality windshield washer fluid or pollutants in the air sticking to the glass. Choose a high-quality anti-contamination windshield washer fluid and regularly clean the glass thoroughly. If you can't handle it yourself, go to a professional car wash shop and let them polish it off with professional tools, but don't do it too often to avoid damaging the glass coating. Simple maintenance can save you a lot of trouble.
Rainbow stains on the car window? Don't panic. First, try washing with warm water and mild detergent. If that doesn't work, spray and wipe with a vinegar-water solution. These marks are usually caused by water residue from improper drying after washing or dirty wiper blades – simply replacing or cleaning the wiper strips should solve it. Prevention is easy: thoroughly dry the surface after each wash and avoid washing under direct sunlight. If DIY methods fail, seek professional car wash services to ensure safe driving without stubborn stains.
