I was putting some glue on my details west salam air filter when the glue spewed out. It filled all the little groves. I have tried to pick it out with a blade but it is not working. Any ideas?
Place it in the freezer until frozen. That makes the glue very brittle and it should flake off easily / easier.
Soak it good in acetone (Finger Nail Polish Remover). Check first to make sure the acetone does not attack the part.
Oh, yeah, no problem with metal. The acetone will soften it up but you may still have to scrub a little with a stiff brush. The longer the soak the better.
