Update and thanks for all of the suggestions.
Used a citrus paint remover followed by electro and eventually removed all of the alum/silver paint. However the cooking surface still had, to me, a shiney appearance-possibly sand blasted at some time? To be sure that all of the paint had been removed, I decided to see if the surface would rust, since I knew that could be removed. It looked liked the entire cooking surface did rust, so another electro and seasoned with mineral oil since it was for display purposes.
Started yesterday on a J. Savory wafer iron with aluminum/silver cooking surface. Citrus remover on the plates. The base is in electro and I think that all the black paint will be loosened today.
Also working on a #7 Savory long waffle iron and base. Fortunately it had not been painted.
Again thanks for all the suggestions. Jerry
