Waste gunwash

[Turbo]

I've done that also, but...

The particulate stuff drops out, so the solvent looks clear, but I think the actual binders remain dissolved.

Have you tried dripping some of your "cleaned" solvent on a mirror? I'd be surprised if there is not some residue.

Which may, or may not be acceptable, depending on the job, of course.

I do this as well & the 'cleaned' thinners is good enough for washing out brushes & spraying equipment but I always use new stuff to mix paint.

Someone once told me that 'gunwash' is recycled paint thinners.

I bet my old Land Rover would run a treat on it.

I used to have a solvent reclaim machine at my old yard.
Had a "special" bag that went in to a pot, poured in the paint/gunwash/solvent hit the run button and clean solvent came out the other side.

Was worth every penny.
Eventually the bag just got full of paint and that went in to our hazardous waste.

If you let it settle and use it as a pre-wash to take the bulk of the paint out of brushes/tools, you can reduce the amount of new stuff needed to be bought. The leftovers get used here for lighting things and diluting rough and ready things, like bitumen or fence paint or waxoyl
