Does wd40 damage paint work

WD-40 can potentially damage paint if left on for an extended period or if the paint is not well bonded to the surface. It may cause discoloration or soften certain types of paint, especially if the paint is older or already compromised. If you need to clean or remove something from painted surfaces, it’s best to test a small, inconspicuous area first and use a product specifically designed for that purpose.
