    Vinegar

    Try boiling it in vinegar. That usually helps get rid of the crud.

    how long to boil?

    Boil for how much time?



    Same for all other radiator vents?



    Same time for hoffman main vents?



    I shouldn't boil a gorton #2, right or wrong?



    Thank you, Dave

    too much pressure?

    Is his vent hissing because the boiler pressure is too high?

    No set time.

    Just try it until it's clean. I'd boil them all.
