Well, I noticed last week that my Primochill white true opaque fluid was looking a bit clearer than it had been. I discovered that the dye had separated from the fluid and built up all over the tubing and blocks.. What a mess. This fluid was just 4-months old and the system ran daily. I was able to get everything cleaned up except my 2 hydro coppers and radiators. I am unable to open the blocks for a proper cleaning so I been trying everything. Vinegar, Primochill's system reboot with no success. I am sure the rads are gummed up so I ordered a Mayhems Blitz pro kit, hopefully that will clean out the rads and hydro blocks....
Any other suggestions if the blitz kit doesn't work???
