I was cleaning mirror box foam with a q-tip for years until a speck of dust ruined a whole roll

I was working on an old Nikon F3 and used a dry q-tip to get the old foam out of the mirror box, like I always did. A tiny piece of lint must have fallen onto the focusing screen, because the next 36 shots all had this weird soft spot right in the middle. Do you guys use a specific solvent or a different tool to avoid this mess?

That foam turns into sticky goo when it ages.

Yeah that sticky goo phase is the worst. It gets on everything and just smears around. Total design flaw if you ask me.

Tell me about it, right?
