For what it's worth. I have noticed that white spirit, used for cleaning brushes and kept in a bottle, solidifies with time. Turps substitute hasn't, for me, and allows me to collect the Turps from the top into a fresh bottle. For wiping down before painting, after sanding I use spirit as it dries whereas the turps leaves a very slight film.

p.s. Sorry I hadn't read the the thread above. Phew I broadly agree.
