Diesel fuel works pretty well. Safety-Kleen has a lot of options. Probably wouldnt sell directly to you, but you can peruse the MSDSs on their website, then you'll have some idea what chemicals to look for at the FLAPS. Usually ends up being some mixture of petroleum distillates. Higher flash point is better from a safety stand point. A few years back they were trying to market Arm&Hammer products but I'm not sure how that worked out. Seems like they would have made their way into Walmart, if they had been successful... Good luck and enjoy the trip. Looks like a blast.

When I bought mine a few years ago from Harbor Freight I am not sure what I put in it but I am pretty sure it was a yellow liquid and in a gallon jug. Well it ate the paint inside the parts washer. I have kept it closed for years and just had the courage to open it up. Yuck! It is still full and looks moldy and gross. After I clean it out, what should I use?
