Received a beautiful .44 hollow base mold
that seems to have never been degreased and never cleaned. There are areas of burned on grease to be removed. I've been soaking it and performing some gentle physical removal. Certainly none of that wire wheel cleaning that some ebay sellers seem to love. Any how, this is as bad as I've ever seen for baked on hydrocarbons. And it got me to wondering about best things to soak in. What do you fellas use?
