Almost certainly, yes. The idea of an "expiration date" for distilled water is a joke by the bottler designed to trick you into buying fresh water when yours is "expired". As long as the bottle is still sealed, it's perfectly safe.
Among distilled, mineral, and top water, it is usually safe to drink them off. Distilled water is the best option as it has had all contaminates removed and is pure water.
Distilled water vapor is safe to breathe. It wouldn't be advised to inhale it, however, just like regular steam.
Yes, it is water with impurities removed.
It does not appear it is advised to flush your water heater with distilled white vinegar.
Any food item that has expired is not safe to eat. That is the reasoning behind the expiration date to let you know how long the food is good. It can cause food poisoning or other stomach pains.
Is there any distilled water for drinking that I should stay away from? I heard from a friend there is a brand that has dangerous minerals in them.
Distilled (desalinated) water is fresh water and is safe to drink. The sea water has been boiled (killing bacteria) and the water vapour (steam) condensed back to water. You may find that the water is actually rather tasteless. This is because you are to used to drinking tap water, to which chlorine and other chemicals have been added, which are not in the distilled water.
Just to be on the safe side, I would use distilled water. Then ask the pediatrician on your next visit.
No. If it was safe, then it wouldn't be expired.
No, you should not use rainwater. Use only distilled water.
open or unopened? if unopened it will be safe to eat long after your dead
I assume you mean whisky. It is unlikely to be any more harmful than any other alcohol, but the quality may have deteriorated.
