Anybody else dog earing their squeegee channels? It helps me to get really close to the edge and reduces the need for detailing. Here’s a link to a UK forum where I learned about dog earing my channels. 
Dog Earing Window Cleaning Tip
I will give it a try. It will be a change. When I cut my channels a like to use a file to round the corners. not to much just a small amount. should be a fun little expieriment.
Question. I have never dog earred my channel and have no problem with the need to detail much. I leave about 1/8 inch of rubber on each end of the channel. If you dog ear your corners arent you essentially doing the same as extending your rubber out further. So why wouldn’t you just adjust your rubber rather than filing and cutting on the channel?
I do leave about an 1/8 of rubber out, Don’t have much to detail. The only reason I cut channels is becuase I am cheap. I would rather buy a large channel and cut it down to a size that I need. I only file the sharp edges so they have a small round corner. Just thought I would try it. A little detail to zero detail could be almost like a vacation?
True. I must be missing soemthing cause I dont see what dog earring the channel does except get the rubber closer. So in theory if you are having a problem you could move your rubber to say 1/4 inch from the channel (non dog earred) and get the same results.
You are by dog earring moving the channel further from the rubber. So cant you accomplish the same by moving the rubber away from the channel?
I always Dog eared my channels… You would be surprised how well it works. It does kill your rubber quicker, but it does work.
We cut our rubbers to the exact same length of the channel. It has helped us in light of detailing. I’d like to see if dog earing the channel and cutting the rubber to the length of the channel makes an even bigger difference.
Has anyone done that?
For commercial, a couple of months ago I started cutting about 1/8th notch out of the corners on my rubber. I uschannels. I still have a small amount of rubber sticking out of the ends (often touching the frame). What I do is try to make the rubber as close to the window seal as possible without touching it (riding up on it). I was really impressed with the difference.
I’ve done that. It works well but it also depends on the window style. I find it is more beneficial with commercial/storefront windows because quite often these windows are in rough shape around the edges on many jobs (lower end stores) and dog-earing your channels apply extra support at the ends. Trade off being that you will wear out the ends a little faster.
I used to dog ear my regular channels. Now I only use Wide channels except for 10inch and under. Maybe there’s a way to dog ear wide channels 
Plasma Cutter Maybe:D
The dog ear pushes the rubber into the glass. I cut my rubber very close to the channel.
I started dog earing about a month or two ago and I am really happy with the results. So much faster. I think I looked up the same sites you did when I got started with it.

Interesting Mike…I’ll have to get out my pliers and bend a few.
When I run into a frame that I know will leave somthing on the edge, I wet the window and takr the end of my squeegee and create a dry edgeon the glass next to the frame. Saves time by eliminating the use of a rag.
Just a little bend, Dwight, not to much.
Thanks for the tip. We cut our rubber to channel length, but I am always willing to give something else a try because there is always a better way out there … and I want to know about it! 
Interesting
Yes I do.
I’d rather notch my rubber than dog-ear channels. I found that dog-earing is only good for 18" & under anyhow. Rubber wear goes through the roof as well. I found that notching beats dog-earing on detail work.
