Had a school to clean today and had a struggle, most of the glass beaded like mad. Some newer windows gave the impression of being greasy and my water would hardly touch it. I came to the conclusion that someone previous had cleaned with chip fat or olive oil! Anyway I still have more to do tomorrow so I checked my TDS and its reading one ppm- surely not high enough to worry about till I get some more resin?

Have you tried TFR?
I know what it is now 

[Davew]

Actually I did and it had little effect really.

Ive cleaned at 5ppm before and it seems ok so 1ppm should be fine.

Bazz...

Ive heard that some people clean at 10 ppm

with what results ?

[Davew]

Thanks should last a few more days then. I shook the vessel up and got yellow water when I first turned it back on. Fine now although its still 001.

TFR will remove most residues,.. but I still try a bit of GG3 on the brush when there are greasy marks on the glass. It works a treat for me!

I have in the past had to clean with a reading of 023ppm i just rinsed off well and they came up the same as if i had cleaned with 000ppm, saying that though i don't know if it would have worked aswell on a first clean.
