Introduction: Paint Thinner Jar Rack
This is a rack made of wood that holds three jars of paint thinner. The top is screwed between two pieces of 3/4 inch plywood with wood screws. The tops have been cut with a hole cutter so that the jar slides exactly up to the ring. See the photos for the ring and how it fits on the unit. I measured this with calipers. The jars are pint-size wide-mouthed mason jars.
Use is straightforward. The first cleaning is in the left-most jar. After using a paint brush comb put it in the middle jar and then finally the right most jar. As you use them, the left most jar will become the most soiled. When it is really soiled, discard it and move all the jars one slot to the left. Clean and refill the soiled jar and it now becomes the right-most jar. So essentially you always have a jar that is almost pristine. This helps really keep your brushes clean. I've found that if I can let the jar settle for a week that the solids fall to the bottom and then I can pour the paint thinner thru a filter and reuse most of it indefinitely.
