A method for purifying used antifreeze is disclosed. An antifreeze recycling systems uses a simple-distillation apparatus adapted to distill clean antifreeze from used antifreeze. A novel scraper blade is used in the simple-distillation apparatus. Also, antifreeze recycling methods that minimize waste and generate nontoxic, landfillable waste are provided. An antifreeze product produced by the present method, and a nontoxic, landfillable sludge product produced by the present method, are disclosed.
