wire brush
John if we use a cream cleaner we use a vileda pointed head scrubber.I think they cost about £5.The problem in the past for us was getting under the small crevice that runs the full length of a frame,we have overcome this now for renovation work,general cleaning we dont really bother going that far.Dan
