PreciClean P42

Amsonic PreciClean P42 is a neutral liquid cleaning concentrate. It is used for ultrasonic cleaning before final rinsing and drying. It removes residues following precleaning and protects metals against corrosion during the final rinsing step.

In addition, Amsonic PreciClean P42 is particularly suitable for cleaning purposes after patination as well as after the acidic pre-treatment.



Amsonic PreciClean P42 is a neutral cleaning concentrate with excellent clean-ing properties. It allows easy and com-plete rinsing. At the same time, Amsonic PreciClean P42 provides optimum protection for all types of metals. With copper and brass, the use of Amsonic PreciClean P42 produces a slightly hydrophobic effect that facilitates drying.

The use of Amsonic PreciClean P42 affects neither the surface gloss nor the further treatment of cleaned parts. It can even be used at ambient temperatures.
