Check the listing for details. Silicoil Brush Cleaning Tank - brush cleaning tank. Condition: New. Listed at 18.06 USD. Fill this 12-oz. glass tank with a solvent appropriate for the chosen painting medium. The Silicoil Brush Cleaning Tank is commonly used for holding turpentine to clean oil painting brushes, but it may alternatively be used with water or other commercial brush cleaning fluids. The tank features an aluminum coil and screw-on lid for storing the liquid between paintings. When changing colors or cleaning brushes after a painting session, stroke the bristles across the inner coil to effectively remove paint from between the hairs and up near the ferrule. The spring-like coil provides a balance of tension and flexibility to aid in cleaning without damaging the brush. Paint particles settle to the bottom over time and the raised coil platform stays clean for continued use.
