Jen, sourdough can certainly affect your bread pan over time, especially if
you let it sit in the pan to "sour up" overnight before mixing. I've had it
"corrode" the metal on one of my paddles.
Your best bet to replace the pan is to contact Regal about a new one....have
the model # of your bread machine handy. Their web address is
