Q: Is it possible to reuse thinner or turpentine?
A: When you submerge your brush in a washer containing
thinner or turpentine and wipe or scrub the bristles on the coiled wire
or screen, the pigment particles will eventually sink to the bottom of
the container, leaving cleaner thinner at the top. Similarly, if you
empty the contents of a brush washer into a storage container, the
pigment particles will settle to the bottom of it as well. After a few
days of settling, you'll find that the thinner or turpentine is
practically clear and ready for reuse.
