    Out of interest how long has your Race Glaze Filter gone on the original filter granules?
    Due to the cement dust issue (now sorted) , I must have washed it and the wifes say 40 times.

    It still seems to prevent the limescale look. But as I always blow dry her immediately afterwards its difficult to tell if its still 0 PPM :)

    If memory serves me well I think they said I should get 36 washes ( well rinse-downs) out of a filter.

    As its been clayed, da polished and followed by 4 coats of Collinite 476S for the winter, I dont fancy doing the acid test of washing, then filter rinsing and then watching to see how it dries!

    I guess as I can not see any limescale whiteout, its doing its job. :)

    I lost the instuction on how to change the granules. I guess its pour out the old ones and flush them out and then replace. :). At £40 its a shame its not just a cartridge swap out.

    I just purchased (less than a tenner on Amazon) a TDS (total dissolved solids) aka hardness meter. RaceGlaze recommends you test your filtered water with one - then you will know exactly when to replace your resin.

    FWIW you can get cheaper resin from other sources.

    I was surprised to find my water is 3x harder than the council says and am now in the process of sourcing a filter and doing battle with Yorkshire Water.

    I’ve done about 40 washes with mine at a guess and the harness meter is still showing 0 , so I’ll keep an eye on it - less washing happening at the moment until Spring

    Doesn’t it depend on how much water you put through it? Not how many times you use it.

    Isn't one a function of the other ;-).

    It also depends on the water hardness and in theory filtering 100ppm will last 3x longer than filtering 300ppm.

    My son had his car valeted today and a 6mth ceramic ....£100.00 Say 2x/year and a couple of washes in-between.

    Makes me wonder if it is worth doing myself. The only upside I see is the exercise...Water, electricity, filter media, cleaning products, protective coatings...........
