Every now and then I’m faced with the unpleasant task of cleaning out my Mona Lisa brush cleaning tank. When painting with oils, you have to clean your brushes with turpentine. When you rinse your brush in the cleaning tank, the oil sinks to the bottom. The cleaning tank has a cool little cage near the bottom.
When the turpentine starts to get cloudy, and the oil buildup starts to accumulate, I have to clean the tank. I find that my colors often get murky when I paint with “dirty” turpentine.
I pour the turpentine in to a large jar to be reused. The oil that’s left in the turpentine sinks to the bottom, and I can use the turpentine again.
Cleaning the tank with water won’t do much to get the oil off. I find that it’s usually enough to just take paper towel and thoroughly wipe out the inside of the tank. I use an old toothbrush to get the oil residue off of the cage.
