Hey guys, I have a quick question. I tried searching for some sort of advice on what to do if u got build-up after hydrx - my comp was stored for a couple of months with water/hydrx mixture still inside (I know, stupid, but i was in a hurry). Now I see some sort of residue inside the tubing and dunno what to use to flush it out. Any kind of mixtures to use to do that? Thx
