Use SUPREME PRODUCTS Blue Rinse to enhance the colour of white, grey, black, brown and coloured coats. This product can be used when shampooing is not necessary or as a final rinse. Use very sparingly - only ¼ to ½ a level teaspoon in a 2 gallon bucket of warm water should be adequate. Leave on the coat to enhance the colour. Test on hairs first and remember these words - 'use very sparingly!' - a little goes a long way!
