Yes it can damage over time if the paintwork is chipped and it ruins chrome badges on vehicles.

[Chris Galloway]

Use protecta-cote on the floor lining

I would never use pure water on my car just incase and even if it was ok might take some of the polish off.

My car gets washed and polished by hand with proper car shampoo and polish

[niceandclean]

Alot of car dealers use pure water now to wash the cars!

[NWH]

Not as pure as you think.

[geefree]

use it on van... and car every week

[RSWindows]

yep, i was just reading some information this about 45mins ago and it does clearly state that pure water is "very aggressive" and will make the rust process greatly accelerated on anything metalic. I was shocked to be honest but after i gave it a little thaught it did make scense.

Have you checked the TDS of rainwater?  I've found it to be around 3 to 7 PPM; so almost zero TDS.

So pure water can't be any more 'aggressive' than rain water.

Not only that, I always use pure water to rinse my car after using a liquid shampoo and wax, and it always comes up great.

And this 'aggressive' is just sales-patter.

i was gonna mention rain, and why would water that has lost some mineral content be all of a sudden more ferocious

I'm not sure how pure water was originally described as 'aggressive' I think it was in some leaflet a window cleaner used to inform his customers how his WFP system worked; or it could be from the Ionics training course.

But it's just a metaphor for saying that pure water has good cleaning abilities.

Oh, and any moisture, whether it be pure water, rain water, or tap water wouldn't be good for the floor of your van, especially in Winter when it'll stay wet pretty-much permenantly.

If your lacquer top layer on your car is not good, don't rinse with pure water, I did, and it left little specs on the entire van lol.

I need to t-cut the thing really, colour has faded.

Pure water will fade your paint in the first place.
Once the polish is taken off the sun and rain will flatten the finish.
Obviously you'll get away with it on metallics.

Di water damages metal big time. my mate is manger of a distillery and the guys who make the tanks told me it is rotting the tanks quicker than normal tap water.

Rubbish.  Professional car valeters with posh vans use pure water.  Fact.

That`s correct,Tosh i clean my van with pure water and the badges are rotting.

[M & C Window Cleaning]

What's the science behind why DI water rots metal quicker than regular water then?

I use it to do my car and it doesn't seem to have affected the chrome-work yet.

YET, being the operative word.

Maybe I haven't done it enough times.
