Bleach is toxic and can cause skin burns if applied to the skin incorrectly. Bleach, on the other hand, becomes less reactive when diluted in water. Even diluted bleach, if kept on the surface for an extended period of time, can cause paint oxidation. As a result, bleach can damage your car’s paint if it is kept on the surface for too long.

If you leave undiluted bleach on your car’s paint for three minutes, it is “too long,” and “too long” doesn’t mean hours or even several minutes here. As soon as bleach is left on a surface for more than 60 seconds, it begins to break down the coating. Diluted bleach can sit for up to three minutes without harming, but you won’t want to take any chances with that.

How To Remove Stains From Car Using Bleach

To be sure, each kind of bleach comes with a set of instructions on how to apply it on various surfaces. Steps like these are typically followed when cleaning a vehicle.

First Step:

Use your standard car wash detergent or compound to clean the vehicle. Remove any dirt from the discolored area. There is no need to wait for the automobile to dry before proceeding to the next step.

Second Step:

Bleach can be added to a glass of water (note: no other cleaning agent or detergent should be added to the water, only the bleach). In this case, a half-cup of bleach to one gallon of water is a good starting point. Check to see if the manufacturer has provided the bleach-to-water ratio for you to follow.

Third Step:

To remove the stains, use the bleach solution and let it sit for a few minutes. Using a damp microfiber towel, gently clean the affected area. At a time, concentrate on one area/spot. Rinse the area with clean water after the bleach has been left on for a short period of time (we recommend no more than three minutes). Examine the area for stains, which should have been cleared by now. Pour a small amount of undiluted bleach (about a tablespoon) onto a towel and wipe the stained areas. This time, you’ll need to wash off in a matter of seconds, maybe 30 to 60 seconds at the latest. If left undiluted, bleach can strip the wax layer off the surface of the skin.
