Goggle care?

Paper towels are generally not good for glasses/goggles (even soft ones are too abrasive).  You need to use something like a soft tissue or special wipes you would use on a camera lens.

I actually try not to wipe my goggles with anything.  Just try to rinse them with clean cold water after (and sometimes before) using them.

Here's what I do with mine

1. Lick them to prevent fogging (forget nasty chemicals that dont work any better than spit)
2. Dip in pool
3. Shake goggles vigorously to get rid of excess water
4. put goggles on and swim
5. rinse goggles under fresh water in shower after swim
6. repeat

I seem to get about four to six months or so out of a pair before they start to leak I buy cheap ones to begin with.
