Hi All,

We've been doing some painting around here, and it's well below
freezing outside. When we had to clean brushes, we didn't have much of
a choice except to use the kitchen sink. We tried to wash everything
down while it was still wet, but (as you can imagine) we've now got
some areas where the paint dried.

Any thoughts on how we could remove it? It's a regular metal basin
kitchen sink. I've tried the oil paint thinner we have and that didn't
do the trick.
