AP1023 is a highly efficient heavy duty soak cleaner. It has high soil capacity, to be easily rinsed off and tolerant to hard water while emulsifies oils and greases and not to collect on the surface of the solution make it ideal to use as pre cleaner before an electrocleaner.

Although it is specifically for iron, it can be used for copper and yellow if surface oxidation (slight color changes) is not taken into account.
