you can get oil dry sold through NEW PIG which you can search out online. This is still a HAZ Waste but it is the safest. Then I would build a modest fire to rid yourself of the rest of the waste. Warning that too hot will warp your pit. You should also look at sand blasting which I just got myself setup with for under $100 at Harbor Freight. I dont plan on doing it often which is why I went with a low grade machine but it does a great job of taking off paint. I would hang some tarps up around the area you plan on doing this as the sand will go everywhere and wear proper masks. It will leave you with the best end product for the least amount of work. Goodluck and post pics!
Cooking for the love of it.
