Mould growing on proving boards / other material recommendations for retarding
We have used birch ply boards for cold proving bagels on for the past couple of years. However as we've gotten busier and the boards have been used daily, they've developed mold growing on them.
We clean this off with vinegar and water solution regularly and the bagels do not physically touch the wood (they sit on parhcment on top of the trays) but I wonder if there is any treatment to the wood that would stop this or if anyone has any recommendations for other materials that we can cut to a custom size (to fit our own proving fridges).
I've thought about getting custom acrylic plastic sheets cut but will cost about £300 / $500 and I'd rather keep the costs as low as poss!
thanks for any tips so we can get rid of these mouldy proving boards!
