Paint solvent-free with Gamblin's Safflower Oil. Use for cleaning brushes while you are working. After your painting session, brushes can be further cleaned using Gamsol and/or soap and water. Gamblin Safflower Oil is a pale, slow-drying oil. Safflower Oil increases flow of oil colors and slows dry times. Use sparingly or mix with an equal amount of Gamsol to create a traditional slow-drying, low-viscosity painting medium. 4.2 oz/125 ml
