Would Reverse Osmosis water be ok to wash a car with?

[W8TLS]

Just what the title say's. Where I work I can buy 5 gallon bottles of it for $1.00.

Yeah, that's fine.

[Jeremy1976]

Yes.

[FUNX650]

Sure, it's "OK"; but, because RO-water
greatly reduces surface tension: don't
be too surprised at the negative effect,
that will be manifested upon the whole
gamut of car-care products.

Good point Bob. RO water will eliminate a water spot issue, but does compromise your soaps, waxes and sealants.

[Mike@ShineStruck]

So either distilled or deionized water would be the better choice.

Would a blend using part tap water and part RO, Distilled or Deionized water give the best of both worlds? Our water is fairly hard.

Also, I've been using distilled water to mix my Sonax Clear View Windshield Wash Concentrate, even though they say tap water is fine. Thoughts?

Here's my home-made RO/DI system for personal use... I use this primarily for the final rinse. 5458254583

How does RO water diminish the effectiveness of other products?

RO water has simply had the dissolved solids removed, similar to, but not as completely as distilled or deionized. Whereas distilled or deionized water will have essentially all dissolved solids removed, RO water is in the 90% - 95% range for dissolved solids removal.

Thanks everybody.

Now for my next question on the subject. What is better distilled or deionized water. I also can get those in 5 gallon bottle's. We make those in-house. We also have a High PH water that we make. All water we make at work I get a discount. $1.00 per 5 gal.

My opinion... One is as good as the other. Whether RO, Distilled, or DI, the end product is very similar... water with reduced and/or eliminated dissolved solid content. They are not exactly the same in a laboratory sense, but for the purpose of washing a car and minimizing or eliminating water spots anyone of them will work.

Exactly!

If I had a choice, I'd pick deionized water without hesitation.
