Give the brush a few good wipes against the interior edge of the paint can to knock off any excess paint. Put the brush under running water while you squeeze the remaining paint out of the bristles. Brush out the last of the paint with a brush comb.

If you're going to use the brush again within a day, suspend the brush in a coffee can full of water making sure the bristles don't touch the bottom of the can. You don't want a brush with bent bristles. For long-term storage, hang brushes from a hook.

Alkyd paint is solvent borne and therefore flammable. Use mineral spirits to clean alkyd paint from your tools. Mineral spirits are flammable so wear gloves and eye protection, and a mask or respirator. Make sure the area is well ventilated. Set up three bowls or cans. The initial wash is done in the first can or bowl. Then, wash again in the second can or bowl. Use the 3rd can or bowl for the final rinse. This should ensure the brush is clean and without any residual paint.

Keep alkyd paint containers closed when not in use. Do not transfer contents to other containers for storage or disposal. In case of spillage, absorb with an inert material such as sand or kitty litter. Dispose of contaminated absorbent, container and/or unused contents in accordance with local, state and federal regulations. Danger: rags, steel wool or waste soaked with alkyd paint may spontaneously catch fire if improperly discarded. Immediately after each use, place rags, steel wood or waste in a sealed, water-filled, metal container.
