Big Dog is a super concentrate, and in most applications should be highly diluted prior to use. Depending on the intended end use dilution rate, distributors will often make 3 drums from this super concentrate before sale to the end user.
Best dilutions on the uncut super concentrate range from 1 to 5 parts cleaner to 50 parts water. When used through pressure washing equipment, drop detergent feed line into the concentrated cleaner, set metering valve to desired setting, and soak entire surface from bottom up. Detail clean from bottom up and rinse from the top down. Big Dog is a very powerful detergent and thus testing a small area prior to cleaning is highly suggested.
