tar removers

[Tom Weed]

Hi everyone,
I've been using Pro Power Sol for my tar remover, which is a pretty strong solvent and worked great on Tar. I am out and just curious what other professionals here use? The Pro line is too hard to come by for me and I would have to pay a hazardous materials charge to order it. I do have Body Solvent but it doesn't' seem to be as strong or aggressive as I am looking for. Does anyone use mineral spirits, or something similar to that?

Thanks for any replies!

Tom
