Smart Grooming's SUPER BLUE - the little pot of blue powder to create absolute whiteness!
Gets rid of yellow stains on white areas and brings brightness and white to greys. Use a tiny amount in a bucket of warm water. A little goes a long way and a 30g pot will last a long time.
Used as a final rinse over the whole body or just on the mane and tail.
Much like the old-fashioned "blue bag" used to whiten laundry on wash day!
