Picked up a #8 Griswold waffle iron the other day and was wondering if I could use this method for cleaning it prior to re-seasoning it. The equipment I have is very controllable and works well at very low pressures. I can use virgin glass at like 10-20 psi and have a very gentle cleaning action and I feel will avoid work hardening the surface. Is this a bad idea? Will it becoming grayish from the cleaning turn black again once seasoned? Or should I just scrub it? It is in good shape. Not really seasoned though. It looks like it just sat around and got a tad of surface rust. Using the blaster is just so much faster than scrubbing..... Your thoughts
