Hello WC community, I am close to completeing all my WC equipment purchases. I just purchased an apogee gt and microres from a member of Hardforums. I noticed some white residue inside the reservoir and i guess its safe to say that residue may be in the water block as well. HOw would i go about cleaning that out? WOuld MIneral SPirits work? Can you guys reccommend a cleaning agent I can use? Thanks
