I discovered the best cleaner I've ever used when my arms started growing shorter as I tried to read. In the machine shop, cutting oil would get splashed on my glasses and then get smeared all around as I tried to clean them with a shop rag. I tried several things, none of which worked very well, not even the perennial aircraft windshield cleaner, Lemon Pledge.
I was at the point of buying cheap bifocals at the Dollar General store and throwing them away when they became too scratched by my shop rag cleaning method, when I accidentally discovered the perfect instant cleaner.
Scrubbing Bubbles bathroom cleaner.
Spray it on, let it bubble for a few seconds, then wash it off. My glasses were as sparkling clean as the day the lenses left the molding machine.
I've been using it as a cleaner for aluminum parts prior to alodining for the last seven years. It removes all oily contaminates, finger prints and the denatured alcohol I use to remove the adhesive from plastic coated skin quality aluminum sheet, effortlessly. Since the acid used to etch the aluminum before applying the hexavalent chromium alodine solution is diluted 50% with water, I don't even bother to dry whatever water drops don't run off. The alodined finish comes out nice and uniform that requires no extra effort to get an equally uniform primer finish with minimal primer.
A word of caution, Scrubbing Bubbles has a warning on the back about using it on acrylics. Strange, considering so many shower surrounds are made of the stuff. I asked a friend, a retired college chemistry professor, about the ingredients and the acrylic warning. He said it was mostly surfecants, hence its ability to just float the dirt away, but couldn't see anything that would directly attack acrylics.He could only guess that if the chemicals were trapped against the acrylic in a seam or crack they might create a reaction over time. I have seen no reaction around the lenses of my glasses, but they only have a maximum life of six months in my hands, so the test is invalid for very long term exposure. I've used it on the lexan on my MkIII for over a year now with no visible adverse reaction, but again, the test is of too short a duration to be any guarantee.
Worth what you paid for it.
