Double K Groomer's Edge Alpha White Shampoo Gallon 32:1
Ratings & Reviews
The 2nd greatest whitening shampoo there is.
I use it full strength or 10:1 (but usually do 10:1) and let it soak into the coat for 5 minutes. The purple color helps tone the yellow out of white coats and leaves the dogs looking beautiful! Smells sort of minty-herbal. I've only found one better whitening in my 11 years as a groomer, which unfortunately isn't sold by Ryan's
