I still think that the recommendations over at CPF by vinhnguyen54 are the best. Shake the reflector in warm water with soap, rinse with clear water, then blow it dry with compressed air. If that doesnt work, lick it, rinse it with clear water, then blow it dry with compressed air.
Works.
wait, you guys are SERIOUS about the licking?
you gotta get 300% of your recommended daily intake of Lead somehow

Hahaha! NightCrawl, thanks. It sounds sensible. I’ll try it soon. 
… stickytape,
purple nitrile glove and dishwashing soap and hot water.
no scratches. the glove keeps it from scratching. i did this to a reflector once with my finger and soap and it scratched it some but with the glove it doesnt.
no water spots though i am really careful to shake/blow with compressed air while the reflector is still hot.

To not get any water spots do the last rinse with pharmacy bought distilled water, it air dries spot free!
Alex, I was thinking the same thing (since I have no compressed air). Thanks.
Not always, if it has picked up sediment as your using it, the sediment will redeposit as the water dries. You can drive yourself mad trying to wash away that sediment, even with repeated washings
Besides, the best use of distilled water is for drinking, it has superior taste to most any water out there
Well, you either really have to know what you are doing or that was a joke. Drinking distilled water can be dangerous.
I think that distilled water will “soak up” the minerals from your body, not sure if it’s a good idea to ingest
why in the world would distilled water be dangerous?
Wow! thanks for all the ideas.
I will narrow it down & post how it does. If you dont have a small air compressor a can of that compressed air for dusting computers works well too.
Just be very careful that no liquid from the compressed air can gets on the reflector, it will leave spots
No minerals in it, can confuse your electrolyte metabolism. People even died from drinking too much regular water..
Told ya 
leaching minerals, thats a myth, one thats been repeated many times over, the minerals in hard water constitute a few percent of our daily intake, and are not highly bioavailable anyways
i was slightly exaggerating about drinking being its best use, since there are many excellent uses for distilled water.
dont’ do it! A can of air s the best or DI water so it won’t leave streaks.
You won’t get your recommended daily allowances from flashlight reflectors alone. You’d need 2.3 servings of baby food to meet that requirement.
