I have been using a reach and wash system for two years with no problems, now I am getting white marks left on the windows after cleaning. I have changed all the filters and the resin, I always keep my brush heads clean and my water reading is 0.02 PPM

Has anyone any advice for what I can check next ?

Is this on 1 particular house or all houses?

Could be off frames old upvc  or not high enough flow rate when it hot use plenty of water to rinse

Maybe you have left white spots before but noboddy has complained.

The white marks are on most properties and with both wooden and PVC frames, the white marks started before the warm weather started, but I will see if turning up the pressure works.
Thanks

Try cleaning your own windows and see if you can work it out.

what flow rate do you use

Just becareful its not caused by upwards splash due to a high flow rate... hard to explain but as you point your jets at the glass as well as the splash circle being underneath it also forms on the upwards edge of where you are looking to rinse and sometime you can rinse the dirt upwards and it can stay on the glass...

A while back someone had this issue and it was suggested that the brush might have got contaminated due to wax residue on the brush from using it for car washing....

Chances are you are not rinsing enough , In this hot weather you need to rinse more than normal as the water is frying faster with dirt psrticles in it which will leave spotting , runs and white marks . Mike
