Emerald Super Soak is a mildly alkaline liquid product, which was developed for use in
immersion and immersion / ultrasonic cleaning operations. It is suitable for use on steel,
stainless steel, brass, copper, bronze, and zinc substrates. I may also be used on
aluminum substrates but will impart a slight etch to the surface. Emerald SS AL Additive
may be added to working solutions at a concentration of 1–2% by volume to completely
stop the etching of aluminum.
