Does Using Toothpaste to Clean the Car Harm the Glass?

[MacDelilah]

Toothpaste can harm the car glass when used for cleaning. Toothpaste is typically composed of many substances with abrasive properties, such as calcium hydrogen phosphate, calcium carbonate, silicon dioxide, calcium pyrophosphate, and aluminum hydroxide. These substances give toothpaste its friction function. If toothpaste is used to clean glass, under light, you can see numerous fine scratches. The correct method to clean car glass is to pour car glass cleaner into a spray bottle and evenly spray it on the interior glass. If you're concerned that the sprayed cleaner might affect other parts of the car, you can cover them with a cloth or plastic beforehand. Then, use a clean, soft towel to wipe the glass. For car glass maintenance, it's important to completely remove any dirt from the glass. The defogging and heating function should be turned off after 5 to 10 minutes to prevent the rear window from cracking. After replacing the glass, avoid washing the car for two days and try to drive on flat roads. If the wipers do not fit tightly against the glass, they can cause scratches and impair functionality, so regular maintenance or replacement is necessary. Also, regularly replace the rubber seals to prevent leaks due to aging.
