Ro & Di Information


Recommended Posts

Hello All,


I'm trying to get some more info on pure water. I don't use it for windows but for cars. I've bought myself a 11ltr di vessel with resin. I've run water through it very slowly and tested it, 0.00 ppm. I poured the pure water over my car put it still leaves slight water spots. I've just tried it on my windows, washed with a soft brush using shampoo, then jet washed on low pressure, but again it's dried terrible.


Do I need a RO system to remove more contamination out of the water.


Would a good RO system then pushed through my DI vessel as a final polish will get the results I'm looking for ?


I'm not very clued up on all this, so any help would be much appreciated,

Dunno about cars but yer windows you just wash with it & rinse with it & just leave to dry. Don't need shampoo or pressure washer.


I'm sure the more experienced wfp guys will give you more information when they get on here.

I was doing my windows just to see if the water would dry without leaving water marks. I'm guessing the correctly filter water would dry clear


Thanks ian

when i clean my van (large citroen relay) i spray with de greaser around the wheels and lower panels, but the top i just use pure water and soft sill brush.


Brush it all down comes up gleaming, just a few bits to touch up but nothing major.

when using pure water for cars you need to give it a propper wash first and rinse off then give it a second rinse with the pure water that should leave it to dry spotless but if youre using a decent car shampoo it should dry relativley streak free try AUTOWASH its by autosmart really good stuff theres a bloke on ebay that sells it in smaller quantities if you dont want to by a big bottle. Just wash your car using the 2 bucket method rinse with clean water then leave to dry, and just buff up any drips, it drys streak free ( dont let the windows dry to much dry them with a shammy or microfibre otherwise theyll get water marks on them)
