I was using a friend’s wfp the other day, and though it cleaned the windows well (experiment at ground level), I noticed very minor spotting as I watched the glass dry (literally lol).
The water coming out was 0 ppm TDS, so I wondered what could cause the spotting. This made me think of those brushes at quarter-stall car washes. If the guy before you went off roading and washed his jeep with that brush and didn’t rinse it, your car will get scratched right? So the same seems to be applicable to the brushes used on WFPoles. The bristles collect mineral content and dirt from windows; maybe even akin to a toothbrush collecting colgate where the bristles connect to the brush. I’m less concerned about scratching glass, but with deposits on the glass from brush transfer. Is this a thing? Seems like it would be…
Is it normal practice to use pure water to clean the bristles or is there some other product used to clean the brush unit after each clean?
There maybe a transfer of dirt especially if you’re rinsing with the brush resting on the glass at an angle. But at 65’ with a fiberglass pole I can’t imagine trying to lift of the glass completely. I find that spotting issues (when you know you have good tds) comes down to proper rinsing. If I scrub the top frame; I do a lot of rinsing and let it drip and come back to do the rest of the glass. Was the glass super hydrophobic @walkthruglass?
During my test with the Unger single stage, one pane was hydrophilic and one was hydrophobic. They both turned out similarly. Likely unnoticeable by customers, but I can see it.
The 65’ work was and exterior job only, and we did the lower glass by hand and ladder, so I couldn’t see the results.
the tds in is irellevent the tds out is important.
proper technique is crucial. there is no more need to clean the brush after each home than there is after each pass on every window.
there is not enough info given to determine the cause of your problem but it is either poor tds output or poor technique.
I have a RO/DI cart from @RHG_Products. You could say it’s a limited edition. It has a bigger DI filter than the tucker cart. Shawn came to the rescue at the end of last summer. I had a crappy system from ABC blow up on me on a job. I was able to pick up one of these systems that was built for Fish who backed out on this model and went with something else.
As for poles goes I have a 38ft hybrid that came with my ABC cart nothing special, but weighs almost 9 pounds. Prior to my ABC junk cart’s RO housing membrane blowing I purchased a Reach-it along with a plus C. Had I Researched-It (see what I did there?); I would have probably gone with a Tucker CF pole. At the time I didn’t know you could add on to the Tucker. I have a crap load of brushes, too many to list.
