18" Channel Vs 20" Channel Which do you use?

Hey All! Would like to thank everybody who has been helping me! Today I was using my 20" channel Squeegee when I noticed it started leaving very thin but noticable water lines. None were forming at the ends but there were at least 3 or 4 very fine lines. I then tried flipping the rubber to no avail. I was then thinking maybe my channel was bent but after testing it on my windows at home it was not leaving any lines. I am wondering if the huge big single pane old style windows were possibly concaved and causing the problem? I would think not because I used this squeegee for about 9 other jobs and it’s been a week and a half and it is just starting to make it. But wouldn’t flipping the rubber over be just as good as replacing it or not?

What about 18" squeegees, it seems those are less prone to leaving water lines but then I am even noticing my 12" squeegee seems to be leaving 4 or 5 thin line streaks, so thin it is razor thin but thinking when rubber wears out it will leave a bunch of streaks. Anyway for large windows do you prefer 18" or 20"?

I have a variety of channels, and it depends on the job that I’m doing as to which channel I use.

As far as your rubber. If there is nothing on it, you could just have a nick in it. Did you try to replace the rubber?

No I have not replaced it yet but the reason I have not is because when I flipped the rubber it still leaves those streaks. My only conclusion is when one side is worn out, the unused other side still wears just the same.

No. The other side doesn’t wear. You probably have a nick that goes across the whole rubber. maybe you damaged it in between jobs. When was the last time you changed it?

How long have you been cleaning windows?

I use a 24 for 80% of my route work . what do you mean by this the unused other side still wears just the same

What kind of channel is it? You should use a wide body channel like Sorbo or slayer if you’re going bigger than 18". The lighter channels like unger get flexy at longer lengths and could cause what you’re describing.

Something to think about is the amount of pressure you are using. Some glass (larger panes) does flex when pushed against and therefore does not make a perfectly flat surface away from the edges.

I think it’s fine now but have learned that while squeeging for any reason if the blade stops, better off starting over and re-wetting glass to avoid a dried streak mark later

You have learned correctly. You can’t stop moving.

Another thing I am learning is to avoid small businesses that have lots of windows. Most small business will not pay more than $20 to $25 tops. That said, better off concentrating on the jobs that have just a couple of large big windows and avoid the ones that have small windows with deep sills. And for another, also learning most businesses that have windows that have been negleted for months need a razor to get them clean

Most business that have neglected their windows for many months/years do not care about clean windows enough. They may not want to spend much on your service. I avoid badly neglected windows unless they ask me.

Point well taken. It’s ironic that most business owners don’t realize when your business looks dirty, it reflects very poorly. I know if I go to Subway and there are two next door, I will always go to the one that is cleaner looking
