How about using foam swabs for lens cleaning?
"CanonAE14fun" wrote in message ... I know that cotton swabs can be used, but it seems to me that the foam swabs are lint-free,where the cotton swabs might not be... Some foam swabs may react with cleaning products, creating a gummy mess-- try it on a window glass first. Foam swabs would hold the cleaning chemical in their 'cells', cotton swabs will 'wick' the cleaning chemical away from the point of contact. Personnally, I would use cotton swabs mainly because they are readily available and foam swabs not so much. If you have a source for them, try it out. |

I know that cotton swabs can be used, but it seems to me that the foam swabs are lint-free,where the cotton swabs might not be... I have to confess I have never cleaned a lens with a foam swab. But then I have never had problem with lint from cotton swabs. There is the occasional long cotton fibre left behind but it is easily swabbed back up by the self-same swab. Clean room swabs are made from urethane foam, which is wettable, so they do absorb moisture. Urethane is what is used in rotted light seals, gooey mirror bumpers, falling-apart hi-fi loud speakers and it produces formaldehyde when used for insulation. I stay as far away from it as possible on religious grounds: I don't care what anyone says, I won't use it and I certainly will never design it into a product. I suppose if the swab were cellulose, like a kitchen sponge, and if it were well wetted and wrung it out it would work. But Q-Tips are cheaper, easier to purchase and you can always find some around the house. For cleaning fluid I use Windex. It takes the dirt off quickly with a minimum of scrubbing. It is scrubbing that damages lenses, not the cleaning fluid. -- Nicholas O.
