Found a hack for cleaning crusty brake calipers without taking them off

I was fighting a sticky rear caliper on my commuter last week and tried spraying brake cleaner through the bleed port while pumping the lever. Cleared out the gunk in like 30 seconds flat, anyone else do this or is it a bad idea long term?

Yeah I've done this a few times on sticky calipers and it works fine as long as you don't blast all the seals out with pressure. Just go easy on the lever and it's golden lol.

Wouldn't risk forcing gunk deeper into the system personally.
