If aluminum… maybe you can pull it off.
If plastic, forget it.
If you really do have to clean it, don’t forget to use the trick to put screen protectors on your Smart-Phone/Tablet so there’s not a single speck of dust on the screen.
Go into the bathroom, turn on the shower as hot as it goes, wait 10-minutes for it to really steam up the bathroom.
The moisture sticks to the dust and makes it drop to the floor; so there’s no dust floating around your bathroom (at the time).
Take tech device into hot steaming bathroom, apply screen protector (or clean lens - clean reflector, whatever); congratulate yourself for getting a perfect score on your mission; now figure out how to explain to fellow household members why you really haven’t lost your mind
That product is just rip-off priced collodion. Collodion has been around for a very long time.
Works well on low curvature telescope mirrors. It would be hard to peel from a flashlight reflector, better to go with a no touch ultrasonic bath style jewellery cleaner.
Don’t buy from Amazon.
It’s most common use is as a medical adhesive for electrodes so pick some up from your local medical supply house. The stuff is priced moderately.
The only time this ever happens to me is if I try to clean or touch one. Never happens otherwise.
I have found that a 1 part Parsons Ammonia to 10 parts distilled water and 3 minutes or so in an ultrasonic works like a champ on plastic or aluminum reflectors. Blow them dry with compressed air. NO TOUCHY!!!
The little ultrasonic jewelry cleaners can be found even at Walmart. I use an industrial ultrasonic but only because we use it for other cleaning. The industrial units can be found on E-bay sometimes for pennies on the $$. ... even new. Beware of used units.
Ha Ha, you got that one right. When I bought my Sunwayman C20C I noticed a LITTLE dust on the reflector and STUPID me LIGHTLY tried to wipe it off and noticed that I was putting some minor scratches on it. Of course I stopped what I was doing but it was all over but the crying. Thank god I stopped when I did.
New clean cotton ball with a little spritz of isopropyl, then dry with more cotton balls until any streaks are gone. Letting it dry on its own leaves spots, cotton balls won't leave scratches. Q-tips don't work - they're packed too densely and will scratch, and fluffing up one end (watch it...) will transfer oils from your fingers and you just end up with more smudges than you started with.
