For a long while - we rinsed the dishes well...
Contrary to what the manufacturers say, that is, that rinsing them off is NOT necessary, we still do. I'd say we rinse off at least 75%. Certainly no food chunks. Very small pieces and sauce-type material is all we leave on them. Now, the previous homeowners, I can't say what they did.
