Attach the roller cleaner to the garden hose and insert the roller into the tube. Hold the roller tube over a bucket, to stop paint going into the ground, and turn on the hose. When the water starts running clear, your roller is clean. Take it out of the roller cleaner, then remove the roller from its frame and stand it on its end to dry. If you lie it down, it'll crush the fibres and create an uneven roll the next time you use it.
Before cleaning oil-based paint off your brush, put on your dust mask and safety glasses, to protect you from the fumes. Pour some turpentine into a bucket and soak your brush in it for several minutes. Swirl the brush around and wipe it against the side of the bucket until it's clean. Then wipe it dry on a rag.
Removing water-based paint from your brush is easy if you do it right after you finish painting. Otherwise, to remove dried paint from a brush, whether its enamel, lacquer, oil or water-based, use paint brush restorer. Put on your gloves, safety glasses and dust mask, then pour the paint brush restorer into a metal bucket. Soak your brush in it, until it looks clean. Then use a wire brush to remove any excess dried paint.
