Degreasing is a key step in the manufacturing process.

It can also be requested by the client as a single treatment; in a pickling and passivation procedure, degreasing becomes an essential step to achieve a good final result.

This procedure has the purpose of removing all the external materials from previous treatments, thus making the metal more suitable for the next operations. The most common types of dirt are: burnt grease, moulding oil, chemical agents used during the manufacturing of the product, imprints, oxide scales, machining waste.

The choice of the product to be used is never inconsequential, since choosing the most suitable degreasing method could maximise the final result, whether it is a single treatment or a preparation of the material.

A good pickling procedure, as any other treatment, has to occur on a surface free of any contamination, or its function would be compromised.
