My uncle stopped flying glow and went to all electric a few years ago. He sent me a few engines. A gms .35 NIB, and 2 OS 25's and a magnum 52 four stroker. Some robart air retracts with struts, and a lot of sullivan glow tanks. The 2 os and magnum engines and some of the tanks had to be soaked in fuel. I have about half a gallon of junked up glow fuel I do not know what to do with to dispose of it properly. Any help would be appreciated.
