Hi Dale, I thought that coffee was a bit acidic, therefore it would make a good drain cleaner.
I've even spoken to a few plumbers who said that coffee grounds were a good remedy for cleaning drains, as the grounds act like an abrasive against the sides of the drain, and the acidic quality of the coffee will latch onto any food particles in the drain and dissolve it. Granted, it's a slow process, not as quick acting as the acid drain cleaners, but a cheap alternative nonetheless. Victor Gouveia
