what do i do with used thinner?

What I do is recycle it. I first put my dirty thinner in a large jar which will function much like a settling pond on a water filtration plant. After a day or two the pigments and other particulates settle out into a sediment on the bottom of the jar with the thinner above being quite clear. After this jar has collected enough clear thinner, I carefully decant the clear thinner off the top into another jar, taking care to not disturb the gunk at the bottom.

From this second jar, I now have recycled thinner that I can use use for any cleaning needs that I have. After a while the recycled thinner typically takes on a greenish hue, but this color tinge doesn't get passed onto any brushes and equipment cleaned with it, so I don't worry about it. I typically do use fresh thinner for thinning paint.

Since I use a Testor's cleaning station for cleaning my airbrush, so the only real thinner loss is whatever elevaporates or is picked up by a paper towel after cleaning. Using this system, I have been been recycling the same quart of thinner for now about six or seven years.

i throw it in a polybag with all my used paper towels and rags that i used for the project, the paper and rags absorb the thinner so i wont have to worry about drips. then it's off to the garbage bin..

Well if you build armor, you can use dirty thinner for washes, it works great if your careful about not scraping your paint job off.

Just put it in an old glass jar (mayo, pickles, etc) without a lid and set it on a shelf in the garage or shed. In a few days - depending on the quantity - it will have evaporated. Then just throw the jar away (or use it again).

thats a good question actually. What i do is i save it up in a container, and when its full i burn it out side, beats putting in the sink. I dont know if u can take stuff like that to the local disposal sites?? id ont know what to do with mysef, apart from burn it.
