In my WC system I've been using 100% Thermaltake Bigwater coolant (don't recommend this BTW). After a few months I started noticing build-up of some kind of a light brown solid matter on the walls of the RES and the tubing. So I need to flush and clean the entire system and probably take apart the water blocks and clean them to. I've heard of people using hot water to flush through the system but I was wondering if anyone has ever tried brake cleaner, Wasn't sure If it would eat though my tubing or not.
And also, what type of coolant or distilled water additive would you recommend?
