So I just got a used freezer, and the thing was pretty filthy. Over the weekend I cleaned it thouroughly, and I'm pretty happy with how it turned out except for the lid gasket. I'm slightly worried about it.
It had quite a bit of black mold on it. After removing the gasket from the lid, and soaking it in a bleach solution most of the gasket looks as good as new. There are a few spots though that just don't want to come off!!
Since it's been in bleach is there no reason to be concerned now, or does the gasket need to be 100% bright white?
