Is there anything baking soda can't do? Apparently not. This wheel is 9.5 inches across and in rather poor shape. It wasn't of a very heavy cardboard to begin with. This was produced by Church & Dwight Company, which peddles Arm & Hammer baking soda. You'd think they'd note that on their wheel, wouldn't you?
I don't know when this was printed, but there are some clues to be found. For example, there's not much call for freshening baby's rubber pants any longer. There is also a recipe for cleaning "vinyl-wear". Clean and brighten!
I wonder how much Helloise would give me for this wheel?
