Hydronic Formula no5 boiler cleaner.

Anyone else try this in their boiler. I put it in my steam boiler and it keeps the water clean. Is there any problem with using this in the boiler

  • dirty water

    the water from the city supply should be pretty clean, unless you know otherwise, so why use this additive, unless you have shares in the company.--nbc

    rust out

    Before I put it in the water would come out dirty at first now that I put it in the water in the boiler stays clean.
