Rain x on visor/sunglasses longevity?

Hi there! Wondering if anyone has been using this or something similar for a while, and can tell me if they have had any problems with hazing or deterioration of the plastic lens. The web site says it’s for glass surfaces, but after searching here I see some of you have been using it anyway. I would like to use it on my giro visor.
Thanks

I might consider it on a clear/non-tinted visor, but I wouldn’t even think of putting it on my sunglasses.

Personally, I wouldn’t the fumes from that stuff that close to my eyeballs. It’s bad enough, just after wiping down the shower walls with it.

I use rain x repeatedly on my cycling sunglasses, which are now in their 3rd year of training/ racing. I have never any issues with either the glasses or my eyes from the product.

I looked at the chemistry of rainX (for grad school project) and it’s DEFINITELY designed around glass surfaces. Basically it’s similar to silicone and chemically adheres to glass (see silicon) surfaces. Not plastic (see carbon).

Sorry dude. Look for acrylic polish of some sort, unless your visor is made from polycarbonate… which I kind of doubt.

I use swim goggle defogger.
(I certainly ain’t using that stuff for swimming)
Works decently, and I know it’s made for plastic viewing thingies.
YMMV.

Do you mean it won’t work, damage the surface, or both?
Not sure about poly or acrylic. It seems to need to be reapplied for each use, which is not a problem (mainly going to use for racing only) humid weather and hot head make for foggy visuals.
Thanks

I believe you, I’d just hate to see it eat into lens of a pair of Oakleys.

I think older formulations of RainX used xylene/toluene as the solvent, which would trash your lenses in a hurry, but they’ve since moved to methanol/ethanol. These alcohols may or may not haze the plastic. The siloxanes in the RainX won’t do anything useful to the plastic, as I doubt they’ll react to make a durable coating.

Either way, I wouldn’t use it on plastics at all, and the label on the bottle says not to use on coated optics (as solvents might damage the coatings)

99% of optical plastic is acrylic–and if your visor is at all flexible, then it’s definitely not polycarbonate. Best weapon of choice for your need is acrylic polish followed by a pure wax (bees/caranuba). The wax will definitely be hydrophobic and should encourage water to bead up and fall off instead of making a lovely fog.

Thanks for the clarification, I will definitely look into your suggestion.
These things are so expensive, and I tend to try to hang on to sunglasses for years by babying them.

I know how you feel about expensive sunglasses.

Just to clarify, I wash my sunglasses by:
1.) Washing my hands (gets them soft),
2.) rinsing off my sunglasses with water (gets rid of sand/salt/crud),
3.) taking one drop of dish soap on my finger, cleaning the lenses.
4.) Blot dry with a towel, then use a microfiber cloth to get it truly dry.

Totally anal retentive, but this is the same procedure I use with my laser optics at school. If you wash your hands before cleaning glasses, there’s pretty much no way they can scratch the lenses and no oil/grease residue either.

For the visor, I’d just try washing it off as aforementioned and giving it a quick waxing. It should do the trick. Definitely don’t need the acrylic polish very often and I wouldn’t use it at all on the sunglasses!

I use this and I cannot even come close to describing to you how much I love this stuff. I have no affiliation with Oakley.

I use this on Tifosi glasses (bike), Rudy Project (run), and, yes (beach).
