    Since the new year my ppm has been at 9-10 in my pure water,started rising a bit before christmas
    should really change my resin but in winter months do folk really look at their windows that closely and cant see 010 pmm in 30 L of water making much difference:cool:

    I was told when i started that 0-10ppm is ok for cleaning windows and thats what i have stuck to. I use di resin only, and now i know, pretty much to the day, when my resin will need changed!.
    Another local window cleaner i know will keep using at 20+ppm!, i told him i didnt think that was a good idea, but he knows best.... :)
