Lens manufacturers say that anything other than a microfiber cloth will damage the coatings on a lens. But microfiber cloths eventually pick up crap and they look like they’re a pain to wash.
How do you keep your lenses clean? Are you using cloth/kleenex or microfiber cloths? If you use microfiber cloths, how do you clean those?
The actual way is to use dish soap under running warm water (not hot apparently, it can damage some coatings I've learned in this thread). First rinse the lenses under a stream without touching them, to wash away any loose debris (which is the reason why you should never use any sort of cloth to wipe them, they just move the debris around which causes scratches). Then use a bit of dish soap on your (clean) fingers to gently rub each lens, which will get rid of any grease or other smears. Then a final rinse – for this one it's best if you use a very slow and even stream as it gives you the fewest water spots, but as long as you don't have super hard water it'll be moot in a few minutes.
This is the way, but you're right about hot water. I did damage a pair by accidentally using water that was too hot.
This method minimizes scratching and it does a great job of removing grease (I sweat a lot) that a microfiber cloth would just spread around.
Yep, and just give them a quick flick at the end to shake off any remaining droplets. Then they’ll dry quickly.
