ive had my brushes fore a couple of years now.i use hot water some bristles are starting to get a bit out of shape but still produce a good job.so im reluctant at the moment to replace.plus im a tight wad.

every 3 months lol 

[ascjim]

thats my extreme brushes tho

[bobplum]

the extremes cant take the extreme changes (see what i did there) in temperatures and i feel aren't robust enough but i like them and will change / buy every 4 months or so

I have a total of 5 brushes for different work they re 5 years and 3 years being the newest and not one is showing any signs of ware. And I have used hot water for four years.

[Frankybadboy]

every time I buy a new pole

[Tony dunmall]

Every six weeks

Extreme dt mixed, hot water does kill them probably last longer if using pencil jets but I use fan

Not until i have worn them that far down that the plastic is scratching the windows!
There is a recession!!! 👀👀

Had way too many brushes. Keep trying new ones in search of the best. Made quite a few DIY ones as well.

Window cleaning is expensive, there is no profit in it.

Just quit.
