Ive seen a few threads that did not have any solid proof of if dehumidied water is just as good or not. So I would like to see what Mike thinks. Im asking stickly for use with mixing dituted products such as an APC/ONR or the like.

I have a dehumidifier at home and thought why not recycle asaposed to dumping. Distilled water is cheap regardless but still curious.

Thanks
 
I think this is going to depend on the quality of distillation in the water you typically buy, but I'd love a solid answer because I also have a dehumidifier.
 
I've been using dehumidifier water since the beginning for all of my chemicals that require dilution. No issues. I had a thread on it awhile back...

I saw your post but still havnt seen anything concrete in terms of why. But your post is also why I'm posting its a fantastic idea.
 
The difference between the too is that Dehumidifier water still has some minerals still in it. It all most as clean as distilled water.
 
I suppose it depends on the operation of your system but a dehumidifier should be taking water vapour out of the air. The water vapour is pure water, it does not have minerals or impurities so the water produced should be the same.

Distilled water should be the same thing. Instead of taking the vapour out of the air, the process actually includes transferring the water from liquid phase to gas phase as well, and then condensing it out.

When you get to softened water, de-ionised, demineralised, this is where variability should come in.
 
I'd be worried about what makes it past a filter with de-humidifier waters?

Besides water, there's dusts, yeasts, molds, etc floating around in the air, besides probably another 100 things.

I know large water purification companies like Culligan usually sell a DI Water, commonly about 25 cents a gallon. Whether this is good enough, tough to say? I imagine such companies can provide a spec sheet on the amounts of solids, and gasses within a water they purify.

Purified water quality, even reagent grade can vary in purity.

I seem to recall places like Whole Foods selling a Triple Distilled Water. Not sure how much better this is than single step distilled. My thinking is if the first distilling step was inefficient, maybe two additional steps does little to improve the quality?

I imagine those who need such waters on this forum would be seeking waters with low solids content, and desire long term shelf stability for diluting solutions for car care useage, correct?

I have heard that water from De-humidifers can pick up impurities from the condenser coils that collect the moisture from the air.
 
Hope I don't disappoint anyone but when I need water to dilute a product I go to the nearest faucet or garden hose and get some water.

The only time I use any type of filtered or distilled water is for use with a steam machine.


I think there's so many other areas to be focused on as it relates to getting perfect results for any detailing process than the water you use to dilute an APC.


That's just me though and while I can get as AR as anyone and more than most it's the water aspect is the least of my worries.


Now when it comes to making a great cup of coffee that's another story...


:D
 
I'm in the same boat as Mike. I only use distilled when running a steamer.

I agree with using distilled or dehumidifier water in a steamer, keeps the machine from getting gunked up with mineral deposits.

APC should not require anything other than tap water, but stuff like mixing up ONR as a quick detailer with DI water I think is a better idea for the paint than using tap water which could potentially leave water spots.

I was never in the industry of retail distilled water but I do know a little about the bottling industry in general. I'd be willing to bet that these manufacturers of distilled water also introduce dissolved ozone into the water just after it goes through a series of ultra violet treatments.

The ultra violet treatment renders any germs or viruses picked up in the manufacturing process sterile. The dissolved ozone sanitizes the bottle and the cap to insure the water quality and shelf life.

The dehumidifier water (in my mind) is a stew of possible germs, viruses and mold spores among other things as was previously mentioned.

Sounds kind of gross to me.
