Never use mineral oil with your paints, it never really dries and linseed does dry so you will get cracks and a dust magnet to the never drying oil (have fun cleaning it too). Castor Oil is the same, never use it as a substitute for painting or even cleaning your brushes. Use Turps to clean your brushes when painting, then dry off the brush using a paper towel so you don't thin out your paints too much. Rule of oil painting: Paint lean to fat. Now what does that mean. You use mineral spirits to thin your paint (less oil, more evaporation) when starting a painting.
