paint thinner... that removes lots of stuff... but sometimes too much. Or just soap and water. a soak in a warm water, ammonia solution works great, but don't soak too long or you can actually dissolve the glue that's holding the brushes bristols in.
Linseed Oil is the best way to thin oil paints. White Spirit can then be used to remove oil paint from brushes.
Denatured alchohol will remove the dried linseed oil from metal, just don't get it on any wood.
you can buy paint that the brushes can be washed out with water.
Linseed oil does not damage paint. Linseed oil is used along with turpentine in oil paints as a type of paint thinner. Linseed oil extends the life of oil paint, makes it easier to thin out, control the paint and paint layers.

Contrary to popular belief, white spirit does not remove hardened paint. It will only thin paint in the tin and is commonly used for cleaning paint brushes.

Try Baby-wipes - they are good for removing dried emulsion paint from hard surfaces.
Simple water with a little soap.
