Acetone shouldn’t be considered a standard “car cleaner.” It’s far better to think of acetone as a last-resort stain remover. 

Only use acetone for stains that don’t respond to gentler cleansers like soap and water. You should also keep soap and water nearby when using acetone to wash it away immediately.

Acetone will start dissolving paint on contact. It doesn’t take long for acetone to begin breaking down oil-based paints, so anyone using it on their car needs to act fast. 

Once you notice the stain you want to remove is gone, it’s time to wash away the acetone with water and soap. For extra protection, some drivers encourage people to quickly apply a coat of wax to minimize the potential damage acetone may have caused. 

Will Acetone Leave A Residue On A Car’s Paint Job? 

If you leave acetone on your car long enough, it will leave behind a noticeable streak that’s virtually impossible to fix. You should never allow acetone to dry on your vehicle. Once acetone dries, you can guarantee it will leave residue behind. 

Please wash away any acetone you use on your car’s paint after removing the stain. By getting rid of any remaining acetone, you will reduce the odds of having to deal with residual streaks.

If you have a stain or scuff mark that doesn’t respond to other cleansers, you could consider using acetone. However, before you start pouring acetone on your car, please give your car a thorough wash with warm & soapy water.

Once your car is dried, it’s best to apply acetone to a cotton ball or Q-tip. Please be sure you wear safety gloves when handling acetone-drenched cotton. You should also work outside to avoid overexposure to acetone fumes.  

When ready, apply your acetone cotton ball to the stain you want to remove. Keep rubbing the acetone until you can’t see the spot anymore. Once the spot is gone, douse your car with warm water and soap. You could apply a fresh coat of wax for good measure.

Some people put isopropyl alcohol in the same category as acetone. While these compounds are incredibly abrasive, you shouldn’t use them interchangeably.

In fact, it’s never a good idea to use straight isopropyl alcohol on stubborn paint stains. Like acetone, alcohol can quickly eat away at your car’s paint job if you’re not careful.

However, some people have used diluted isopropyl alcohol to remove staining from their windows or to get rid of tree sap. 

If you want more detailed information on safely using diluted isopropyl alcohol on your car, be sure to watch this video:

While acetone is a great tool, remember it can eat into your paint the longer you leave it on your vehicle.
