Stone Soap’s Kemade A & Blue Demon presoaks are designed for frictionless washes and pack a one-two punch. Kemade A is a combination of acids and penetrating agents, producing a low-pH liquid presoak that quickly removes road scale. Add to that Blue Demon, a high-pH frictionless presoak, to produce great foam that rinses easily. The combination brings shine to chrome, and both can also be used in conveyor washes with low pressure. Products are available in 5-, 15-, 30- and 55- gallon containers.
