Quality products for pickling a variety of metals

Pickling is a necessary process to thoroughly clean metal surfaces or to prepare them for other processing steps. This chemical process removes oxidation, removes applied metal layers or creates an oxidation-free surface.

Emil Otto’s pickling products are used in modern production facilities and a variety of applications.The pickling agents from Emil Otto can be used to remove oxidation during the production of cold-rolled steel strips, for example. When processing aluminium parts, the pickling agents also help to remove unwanted oxide layers in preparation for long-lasting and stable joints. In addition, pickling agents are used to optimise surfaces in the treatment of stainless and acid-resistant steels after heat exposure.

Our pickling products are specially developed to meet the most demanding requirements. They enable effective metal treatment, for example, of copper, where pickling is indispensable both as protection and as a preparatory step for subsequent processing. For iron and steel, pickling is used for optimal surface preparation.

Stainless and acid-resistant steels require thorough cleaning after thermal processes such as welding or annealing to ensure a flawless surface. For aluminium processing, we offer specially formulated pickling solutions that improve the adhesion of coatings or compounds and guarantee a clean, oxide-free surface.

For darker shades, we offer a black pickling that can be used to create a decorative and protective layer on a variety of materials.

The pickling products from Emil Otto are versatile and can be used for most metals. They are also available in different packaging sizes.

Pickling with Emil Otto - also ideal for paint removal

With Emil Otto, you benefit from high-quality and versatile pickling solutions that not only optimally prepare and refine metals, but also painted surfaces.

In addition to metals, we offer proven solutions for the removal of paints and coatings. Our paint pickling solution ensures that old layers are reliably removed to expose the underlying surfaces for further processing. Our stain enables clean and residue-free surface treatment. 

All pickling products are available in different packaging sizes.
