Hydra-Scale CD1 is a descaling system based on a synergistic blend of safe organic acids and sequestrants. It will safely and efficiently remove a wide range of heat scales and oxidation products from the surface of brass, copper, steel and aluminium, leaving a bright, stain-free finish. CD1 is safe for operators and, at greater than 90% biodegradable, is also safer for the environment. Its powerful cleaning action uses natural citric acid to remove scale and oxidation and leave surfaces grease, oil and grime free.
