help! black mold in banneton and liner

Toast

Black mold has started to develop on my banneton and liner. I tried washing the liner in bleach and stain remover a few times in hot water and the spots are still there!

I don't use a liner, just the banneton, but got green mold pretty soon after I got it, because I wrapped it in a plastic bag immediately after each use.  I can't help with the liner, but bleach with a toothbrush got my banneton mold free.  Now I make sure it air dries for at least a full day before I put it in a plastic bag.  

the banneton in the almost cool oven after baking.  We live in a coastal climate, so air dry often isn't enough.  I rarely use a liner and am no laundry expert, so can't help with that.  I'd just replace the liner if the mold won't come out.
