i purchased a can of this (plexus) stuff 12 years ago and the other day i saw it sitting on a shelf nearly still full. i got it for motorcycle face shields but didnt like it during night use so on the shelf it went.
i usually clean vision stuff with soap and water which is a pain so i take too much time between cleanings. this stuff is really nice and simple to use to keep your lenses super clean, im not sure what it does that is different but vs soap and water my smoked out welding helmet clear lens looks brand new...aside from the spatter damage. its the best thing ive ever tried on my laptop screen as well.
i was sort of shocked when i checked the price of it these days but heck, i imagine even with regular use a can would last me years.
