What is the best chemical pipe cleaner and how do you use it? I have a outdoor wood furnace hydronic system and I neglected adding rust inhibitor. Chunks are breaking off and screwing up the zone valve. Does anybody out there have any idea?:D

Thank you HVAC but you see I'm in Canada and I was wondering about Home Depot.

Wow I have no idea about Home Depot. I have never bought or never will buy and HVAC stuff there. If you call the number posted in the information I sent you they will tell you where you can get there product or a similar product in Canada.
