Cleaning Solutions
Solution Types
Water-based solutions can be either slightly acidic or alkaline. They
include detergents, soaps and industrial cleaners designed to remove
specific soils.
Acidic water-based solutions: remove rust, tarnish or scale. They
range from mild solutions that remove tarnish, to concentrated, inhibited
acidic solutions that remove investment plaster, milk-stone, zinc oxide
and rust from steel and cast iron as well as smut and heat-treat scale from
hardened steel.
Alkaline water-based solutions: include carbonates, silicates and
caustics. These cause emulsifying action, which keeps soil from
redepositing on the cleaned surface, and improves cleaning action in hard
water.
Do not use alcohol, gasoline, bleach, mineral acids, solutions with a
flash point, semi-aqueous or combustible liquids in ultrasonic tanks, or
you will void the warranty. Only use non-flammable solutions and water-
based solutions.
