[Ten Hammers]

Common used oil ( oil changes ) works pretty well. so does Linseed and Watco as well ( like Jens stated ). Coal, gas or acetelyne all bake finishes good. Just got to be careful and not get too hot. Happens fast sometimes. I burn Watco rags or linseed rags after use ( coal forge ) or just torch them and let them burn under the hood. spontanious combustion is scary stuff. I let the used oil rags ( actually blue paper towels ) air dry and have never had an issue with them but I keep my eye on them. Never let them accumulate too much and keep them in the open air in a place where they COULD BURN and not create a problem ( steel bucket works ). You need a rigorous program to shut shop down. Same game every day. Compressor, bottles, forge(s) etc. all need to have attention paid to them. Rags and other fire potentials need dealt with. Class "A " fires are the main problem in my shop that need to be kept under control ( towels, newspaper, trash). I keep stuff liike this picked up pretty well but need to stay on it.
