Deionized Water - Prime Demineralized Solution - Certified Laboratory Grade DI Water - Sterile for Deep Cleaning, Cooling, Cosmetic, & Hygiene

I've no way of testing but it appears to be what is claimed. I used it as the final rinse when cleaning LP's. When used for this the drying time is less than half of when you use distilled water instead. This indicates fewer impurities, at least that's the explanation a chemist gave me. Type 1 is even better but the difference isn't worth the price.

Prompt service, perfect water for my needs

I needed really good water to cleanse my wounds, not some special high-priced water that doesn't seem like it's worth the price, but THIS water does the job very well. It's very, very clean and works better than the over-proced water to cleanse my wounds. It's even better in the radiator in my car. It seems free of contaminants that would shorten the life of my car. I really like this product !!!

I was skeptical about using deionized water to clean my carpets. But using it for the first time .I was shocked at the results.It works much better then traditional carpet cleaners. No left over residue or chemical smell.

Great product to have when steam mopping floors

Its a gallon of water with a ph of 6 and ppm of 1.

It's literally JUST water. But it does that well. Don't drink it.

This product made my linoleum kitchen floor look new when used with my floor steamer. Definitely made a difference from regular tap water.
