But you would have to know what your doing to use it so not really practical for most folks.
Methanol works well as a cheap defoamer. Commercial defoamers are usually a bit pricy Silicon suspensions.

Phosphoric acid with very hot water will remove the calcium deposits....but in cold water takes forever.....problem is you don't know what anyone has in their tank to begin with....like bleach which will make poison gas..... and don't know what formaldahyde and acid will do
