I have been replacing my RGP every year because after a while they
form a white film on the outer edge of the lens which I am not able to
clean. It bothers my vision if I blink my eye and the lens is sliding
over the eye. Also, I have noticed this stain appearing after I go for
a long drive (out of State) and the air contantly hitting my eyes,
making my eyes watery. Or if I am outdoor a lot and my eyes get
wattery. Is there a way to have these stains removed at home....Some
one said use baking soda?

I use at home Boston Cleaner to clean and then Boston Simplicity to
store my lenses overnight. Why these white stains when they start
appearing on my RGP, I am not able to clean them off. Do I need to use
some other cleaner along with Boston one? Is baking soda Ok to use?
Please help...

Thanks a lot.
