For oil-based paint, Henrique uses odorless mineral spirits. For a brush, pour solvent in a small container and swish the tool from side to side, using the edges of the container to push out paint. Then give it a rinse with clean mineral spirits. For a roller cover, remove excess paint with a 5-in-1, dip and roll it around in a paint tray filled with solvent, and do a final rinse with clean solvent.
