Hi All, I have done a search on this site about cleaning a lens and to my suprise didn't find any advice (mind you my eyes are going )

Using a lens cleaning kit from a photographic store...the pack of tissues and plastic bottle of 'squirt' often make marks on the front or rear element surface worse rather than better.

Any suggestions on what to get from the chemist to shift those stuborn stains? I geuss pure alcohol will be in there somewhere??

Cheers Dave
