Product to break down “coffee grounds”?
Has anyone come across or had positive results with any substance to help break down and clean “coffee grounds” out of condensing boilers?
Not so much a problem with water tube but with fire tubes especially using LP.
Deposits get lodged into tubes and it’s very difficult to remove. I use a coil jet sprayer for cleaning condensing boilers and it only does so much.
I don’t want to beat a dead horse here but any known products to dissolve this stuff?
