DFX teal is highly pigmented and may leave a faint stain temporarily. Global Teal is the least likely to stain, though it isn't so strong on the green side. Apply with a dampened sponge or brush. We recommend that you apply water to your brush or sponge and then load the makeup rather than spraying your paints. Most colors remove easily with soap and water. Make sure to let your paints air dry out by leaving the lids off between uses.
