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.
does that melamime milk contain lead?
you can’t even buy leaded gas anymore, damn socialists
Yeah, you guys are totally correct about distilled water and all those freaks that actually studied the subject are wrong. Alright.
As I said, it can be dangerous. It doesnt have to be, but I wouldnt recommend it. If you drink too much water, you die. Same happens with distilled water, but earlier. And drinking distilled water only - while not watching what you are eating - can mess your electrolyte metabolism up, resulting in some nasty and unwanted side effects. But do what you want, its not my health. Just dont give silly advice.
Are you saying ‘the studies’ prove distilled water is dangerous or not dangerous?
I don’t think tap water contains a high concentration of potassium or sodium chloride, otherwise you wouldn’t die from water intoxication.
It can be dangerous. I cant see how I could possibly have made it clearer.
So if distilled water will mess up your electrolytes but tap water doesn’t have these electrolytes, how is drinking distilled water dangerous?
I dont know where you live, but there is a lot of stuff in tap water you wont find in distilled water..
it shouldn’t mater where i live because lack of this stuff you speak of anywhere on earth would have killed me and millions of others already, but what is this stuff that makes tap water undangerous?
Are you sure you really know the difference between "water" and "distilled water"? Maybe you are talking about deionized water rather than distilled water.
There are people who spent their whole lives on those subjects.. our electroylte metabolism is rather sensitive. Thats why athletes dont trink water when they do sports.
You are correct the electrolyte balance is sensitive, but our bodies have an elaborate system for maintaining homeostasis. Thats why we don’t have to take measured supplements of sodium chloride and potassium daily, and the news is not filled everyday with reports of thousands of people who died today from lack of these nutrients. I once read theres a theory that the reason why we like salt so much and have strong receptors on our tongues for saltiness is because salt was rather rare in our distant past, and we of course require it to survive. However today in the developed world we consume more salt then is needed, people with heart conditions are put on low salt diets, and everyone is supposed to limit how much salt they take in. Salt is even listed in nutrition labels so you can avoid high salt foods.
And you just proved my next point, if tap water had significant quantities of sodium chloride and potassium, athletes would be drinking it exclusively.
