Walnut oil effectively removes color from artists' brushes and is a natural vegetable oil that does not evaporate or remove essential oils from the artists' brushes. The addition of walnut oil to color will slow drying, enhance flow and increase sheen.

M. Graham's walnut oil medium is designed to augment the special nature of their oil color but is also completely compatible with other artists oil colors and mediums.

We recommend laying out your rags and towels containing walnut oil and/or walnut alkyd in a single layer until dry.  Once dried they can be disposed of.
