How do I clean the inside of my goggles?

i guess you can wash it and destroy your anti-fog and then go buy more anti-fog and spray it on

I've always just wiped them, haven't noticed anything different

I think your just not supposed to wipe your anti-fog if there is too much humidity in there, it should be alright wiping it if it is dry. Not 100 %, so wait for what the others say.

Spit an rub

I could be totally wrong about this, so if I am, someone please correct me.

Since I also wear glasses this is what I do. Learned this from my eye doctor since my new frames have a special coating on the lens.

Never wipe a dry lens. It can drag oils, dust, dirt, etc across the lens and create micro scratches which can accumulate over time and lead to degradation. I use a small amount of water and cover the surface, then using a tiny amount of dish soap and warm water wash the lens with a chamois type cloth, or sometimes will use my fingers if they're clean. I'll clean everything up with a chamois type cloth too. Has worked great for me in glasses and goggles.

But, like I said, this could be not the best method.

I usually just get a tip of a towel or something damp and then wipe. I've never really had a problem

thanks for your advice guys. +k
