What!? You cleaned your filter with a jumper!? I'm sending the Filthy Filter Police round.
It is quite a normal reaction from an old hand who has never broken or scatched a filter.
(But an old hand who has screamed at the loss of several Käsemann polarisers to rivers, creeks, under car wheels and petty-minded, lily-livered, pink-pawed pilferers...)
PS: Have you started the cleaning job of the lenses yet?
