Question:

Can you help bail this customer out. His Economy Foam Gun got all gummed up and he still has 3 Pro Cans of Foam left that he wants to use. What can he do to get it back working

Aquascape Tech Answer:

So I am assuming that he cannot get a can of cleaner threaded onto the gun? Otherwise I have heard of contractors submerging the gun in antifreeze for 24 hours & that will dissolve the hardened foam.
