Glass Cleaning Frequency Research

@anon46335951, @Henry, thank you both for input on the best way to sell! I usually don’t bring up this point with customers, and recently I have been doing demos which have really helped my close rate so it’s good to know I am on the right track! I guess I was looking to use the potential damage side as part of my sales to the bigger customers around here just because they don’t know almost anything about window cleaning and care, but I will stick more to the cleaning sale point. It’s good to know what works! (And what is accurate!) Thanks again!

All of this is great! And you are most welcolm. I would be careful of silica spotting with a WFP. That is all. It can start out invisible. Then one sunny day;…

@Henry, silica spotting? Are you saying the pure water draws out the silica in the glass to where you can’t get spot free results?

Water can have a high silica content. The silica comes from the earth, not the glass. It cannot be detected in your water with a typical TDS meter. Silica requires a special meter. The commercial pure water systems that guys use for WFP work are designed to remove other minerals. Not silica. These are the reasons why silica spotting can be a problem. It usually starts invisibly. Then it builds over time. Finally it can be seen in the direct sun. Especially on the second story windows. If you want to know if you have silica in your water you must use a special silica tester on the water coming out of your system.

@Henry I have one storefront that I clean every 4 weeks, and I used my wfp on it about 5 times. I did seem to notice spotting that I didn’t remember before when I had finished the last time, and I thought the spotting was odd, but then I used a squeegee and didn’t see it anymore. So I’m guessing if it had been silica it wouldn’t have come off? It seems that it is rather hard to remove silica as well, thought I found online that a strong anon should work?

You could get a silica meter to check your water. But I have to say I don’t know how to remove silica from water. There are others on this forum that know way more than me. When silica does become part of the glass surface it isn’t easy to remove.

I agree, this works well with hesitant customers. Clean one window, show the results, job sourced! By the time you’ve discussed the technicalities you could have done half the job.
