Used goggles question
First off I'm new to this sport, I went once this year and got hooked.
This site has been a great help, so thank you to all who help out the newbs.
But i digress,
So im thinking about buying some goggles and on this site and other places there are some good deals on used ones. My question is how would one go about cleaning and disinfecting a pair. I more focused on the padding that fits flush on the face, is this part replaceable or just a few squirts of alcohol?
