Hello together, I have a small, big problem: The last thing I had to do was attach my flasher glass with a tape, because the holder was broken off. In the workshop I was given a very strong tape. After a hard work I was able to remove the adhesive residue. I worked there with a sponge and shampoo. Unfortunately, the places where the glue was on it are now “wholey”. When I go over it with my finger, I notice that there is another layer on it. I tried to remove these impurities with the wash gun, but it doesn’t work. It didn’t work with a magic sponge either. Otherwise I would remove such impurities with an oil like WD40. How should I proceed here? Maybe with an oil (ballistol) try to clean it up? Thanks already in advance. LG, Muto
