I understand everyone has their own way of doing this. Some use spirits, some oils etc....
Personally, I tend to use odorless turps, but on occasion will use oil to clean a brush between colours if I don't have 2 brushes of the same type for darks and lights.
Over the years, I have tried various ways of doing this. A simple jar with a brass pot scrub in the bottom to wipe the brush on works OK, but can be messy.
Art shop bought super-duper container soon lost a wire brush wipe and has no lid, so the solvent just evaporates twice as fast.
Recently I broke a teapot. I discovered the strainer fits nicely in the neck of a Moccona coffee jar and the lid fits within the top of the tea strainer. I have been thrilled with my discovery. Gentle on brushes, little evaporation, no sludge to deal with daily (only when cleaning out).
the 3 pics on the left are the tea strainer in a coffee jar and the one on the right is the useless shop bought model.

What contraptions do other people use as a container for your preferred brush rinser/cleaner?

@outremer, Until 3 weeks ago I was doing a similar thing. I had 2 or 3 small jars from sludgy to clean, they took up space, and often got knocked over. I think that is why I am liking the tea strainer, the level means the strainer part is always clear and the sludge is somewhere below.
Paper towels are wonderful things. Keep the logging industry going and more trees planted; what more could you ask for .... well, I would like my local supermarkets to bring back unbleached paper to the shelves...!
I recently bought some of that foamy brush cleaner. I have used it when packing brushes away, but have steered clear for everyday use. I don't like wetting my oil brushes with water.
While painting, I have up to 20 brushes going for the different colors but if I need to use a brush for another (but similar) color I just wipe it like Mark shows in his video, dip it in the new color, wipe it again and I'm ready to go.
There's a thread here somewhere with pictures of the jar with holes in the lid with the brushes inserted. I'll have a search for it and post it. A picture tells a thousand words.
