My UPVC has gone yellow where I sprayed the activator for Mitre Bond. I've tried Isopropyl, UPVC cleaner and water, but they don't seem to make a difference. How do people usually deal with this?
I could try using a cream cleaner, but that will be a polish and will change the finish, so that's a last resort for me.
I guess it's best to put the glue on the fascia/soffit and spray the inside of the cover strips to avoid this problem?
