Why does nobody talk about how much angle matters on the bottom of a brush head

I spent 15 years using a flat cut on my poly brushes, thinking it was the standard way. Last fall I watched a retired sweep in Lancaster round off the tips slightly and suddenly I could get into those tight spots near the damper without scraping the sides. Has anyone else tried reshaping their brush heads or am I late to the party?

Oh man, I tried that with a beat up brush and it actually worked better for cleaning narrow window tracks.

I used a worn-out toothbrush on my kitchen windows last spring and it got into the corners way better than those fancy little attachments. The bristles were soft enough not to scratch the frame but still scraped off the gunk that builds up over winter. I think the key is finding one where the bristles are still straight but just slightly bent at the tips. You probably want to soak it in some soapy water first to loosen everything up before you start scrubbing. It also helps to run it under hot water mid-way through to clear out the dirt that gets trapped between the bristles.
