I have been using extreme brushes for a couple of years and am generally v happy with them. However, where they fail is scrubbing off insect poo.
On ground floor windows it's not a problem. Scrubbing with your finger nail or a scraper and its gone. Higher up though it just sits there defying your attempts.
I have some old ionic brushes which have fantastic scrubbing power but are heavy in comparison.
Anyone gone back to heavier, scrubbing brushes?

best to start with that window first and let it soak, then clean the other windows while its soaking, then go back to it.
but dont go back to a heavy brush!

Yeah, i do that with bird strikes and it works ok. I am talking about the yellow/orange stuff about 1 or 2 cm long and a few mm wide. it's baked on hard and needs a scrub to get rid.
Also the heavier scrubbing brushes are almost indestructible. Would be nice to have a light brush but with good scrubbing power.

Use the stock, cushioned by the bristles.

Yeah that's bee poo and can be hard to shift.
As 8 weekly said: angle the side of the brush and compress the bristles so you can use the hardness of the brush stock but with the bristles protecting the glass from getting scratched.
