How to Store oil stained paint brush between use?

Answer 1

Clean it with the solvent of the material that you used. If it was an oil-based or alkyd product, pour approx.4 oz of mineral spirits in a plastic mixing cup, rinse brush repeatedly and clean brush w/ a "brush comb". Store brush in original wrapper it came packaged in (higher quality brushes). Keep a lid on rinsed solvent for future use or dispose of according to local environmental laws. For water-based or latex paints rinse w/ a warm water and laundry detergent solution and comb brush and store in same fashion as above.

Answer 2

If you are storing a paintbrush used for an oil based paint or stain overnight with intent to continue working the next day, an old painters' trick is to wrap the brush tightly in plastic an put it into the refrigerator or freezer. The cold retards the drying of the paint or stain.

Do not put a brush with latex or acrylic paint (or stain) on it in the freezer... it ruins the paint and you will need to clean the brush before you return to work. If you will be away from your work for more than 24 hours it is advisable to thoroughly clean the brush using the appropriate brush cleaner.
