clean

Just picked up some banneton's from ebay for around $13.00/piece!

I would like to clean them before using.  I'm thinking of using only water, and then throwing them in a 150 - 200 degree oven to dry.

My other thought is just to flour the inside, and if there is bacteria/germs, at 450+ degrees, anything harmful should be killed anyway.

Thoughts?  Should I use soap & water?

Thanks!
