In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Hello folks I've been tasked with removing antifreeze from a staple up radiant floor. The tubing used is Onyx. Now I haven't started this yet but from some past experience I've found black gunk in the systems where Onyx has been used. I would like to know if there is any thing I can use to "clean" this and or neutralize the spread of the gunk?
thanks for any advice.
