HaHa...I do the same thing when I'm out fishing with my Costa's.Expensive Oakley glasses are mainly expensive because of the brand name not the quality of the product so much. I have an "expensive" pair of Maui Jims I simply lick with my tongue and wipe with a cloth that came with them. Works perfectly. If they actually have dirt on them rather than just dried sweat I'll use dish soap.
Don't use fingernail polish remover, it will scar the plastic. In fact, stay away from solvents.I use Acetone on the cheap ones.
what is the best solvent to clean expensive oakley glasses lens?
Oakley has cheap lens?
The OP trolled asking about "solvent", Acetone is a high quality solvent.Don't use fingernail polish remover, it will scar the plastic. In fact, stay away from solvents.
I agree with using dish soap, it de-greasing capabilities also work well for grease stains on clothing as a pre-treater too. Using spit and your t-shirt will most likely scratch the lenses. Use a clean terry cloth/micro-fiber towel to dry and wipe.
