how pure dos the water need to be when cleaning glass ?
i used my water with a high tds yesterday and i mentioned to all my customers that the windows minght not turn out right and if this was the case to phone me up and i would return to reclean , not had 1 call so how pure should the water be .

Not as pure as most think IMO.


I worked a full week with 010ppm & had no problems at all.

i have worked with 50 by accident, and i know a few that use 15 ppm all the time

i without realising was working with tds of 62 last week. after checking them all i found no spotting at all. id like to know what the big deal is with having 000ppm as many of us must be wasting so much money on resin when could get away with just an ro.

if you want to use deionised water then it needs to be 0ppm, but it is not necessary for it to be so low to clean windows.
highest i've used was in the 20's ppm, made no difference.

but it was a one off when DI only.

my RO produces at 1ppm but i put it through a DI, just cos i like 0ppm

there is something about DI water that is one of the most aggressive cleaning products around. it will attack metal & plastic. even stainless steel.

check this discussion about the consumption of DI water:

ours is 10-20 at the moment, no problems at all. going to order more resin this week. we dont use resin at all through the winter, just dont need to.
