I was looking at these over Winter to save time when washing the car but thinking about it, it makes more sense over Summer!
Does anyone use some sort of inline water de-ioniser when rinsing down their car? I've come across a couple on Detailing World and Google but the one that a few people mention I can't seem to find online.
For anyone wondering, you stick a de-ioniser between tap and pressure washer, it filters the water removing which means you don't have to manually dry the car. It's the minerals and impurities in the water that cause dry stains on the car, so this way means you just wash, rinse then leave to dry in the sun and it should be mark free
Ones I've come across and wondering if anyone has any experience with them are -
Aqua Gleam - http://www.theultimatefinish.co.uk/aqua-gleam/0ppm-de-ionising-water-filter-30.aspx
DI Vessel - http://www.daqua.co.uk/divessels.htm
Raceglaze Water Filter - http://www.raceglaze.co.uk/race-glaze/400-litre-0ppm-car-washing-filter/
I'm assuming the Aqua Gleam is overpriced as it's marketed towards car enthusiasts and a tank with crystals/resin in will be cheaper and do the same job?
