Super Blue by Smart Grooming is a little pot of blue that will give added brightness to whites and greys.  Use diluted on manes, tails and bodies by diluting ¼ teaspoon of Super Blue powder in approx. 3 litres of warm water. Stir well and then apply to areas.  For tails, dip directly into the bucket and leave for no more than 30 seconds.
