I recently bought and mounted a 20mm tgn finest and it seems to have those gel like tips that some talk about. Its great and all, but the darn brush seems to be impossible to get the soap out or something.. the tips get kind of hard and stuck together when it dries. I keep running tons of water through it but it stays gel-like and always dries hard.. any suggestions on how to get it out or maybe someone else had the same experience.
