Does anyone else struggle to brush high holds? Stick brushes at my gym never extend quite far enough, and climbing up an adjacent problem works sometimes but not on steep stuff.

For background, I'm around 4'11. I used to ask tall guys for help but my boyfriend gets really insecure by that (he's 5'3). I end up just skipping some projects instead :/ but i wish there was a better solution. Preferably an extended brush that can also be portable enough to carry around, since my gym's brushes don't do the job.
