Three-Stage Brush-Cleaning System
Save time and mineral spirits with this three-container brush-cleaning method. Partially fill three containers with mineral spirits. When you're done working for the day, swish your brush around in the first container. Wipe it along the edge of the container to remove as much finish as you can. Then repeat the process in the second container. By now the brush will be pretty clean.
Suspend the brush in the third container. Drill a hole in the handle and suspend it from a wire or dowel so that the bristles aren't resting on the bottom of the container. Put a lid on the first two containers, and wrap plastic wrap or
aluminum foil around the brush handle on the third container. You can use the same mineral spirits for several brush cleanings.
When the first container gets too full of old finish, dump it into a fourth container labeled “used mineral spirits.” Shift the second and third containers to positions one and two, and pour clean mineral spirits into the one you emptied and place it at the end of the line. You can reuse the mineral spirits from the “used” container after the finish settles. Decant it carefully to avoid stirring up the gunk on the bottom.
