How I can get Yellow Highlighter on a painted wall?
Some time ago in my childhood, my friends and I would draw on the walls with a marker yellow, and would be invisible on my walls painted blue. But when it showed a black light on it, is to shine and have a cool effect. But now I want all these designs out. What I can use that will not damage the paint? I really do not want to paint the whole thing-_-Thanks for your help!
I would try to clear ammonia with a soft sponge ive found that this is a very effective cleaning agent
