Metal façades give modern buildings a high-quality, long-lasting character. But over time, dirt, deposits and environmental influences visibly damage them. Regular cleaning is therefore essential to maintain both the appearance and function of the surface. This poses a key challenge: how can metal be cleaned effectively without encouraging corrosion?

Many conventional cleaning agents attack metal surfaces unnecessarily. Caution is required, especially with sensitive materials such as anodized aluminium or painted façades. Cleaners that are too aggressive can trigger harmful chemical reactions that accelerate corrosion instead of preventing it.

With the specially developed products from AcroTec, however, metal façades can be cleaned gently and sustainably. They are used, for example:

These cleaning agents are GRM-tested, which certifies a particularly high level of material compatibility. They work effectively against typical soiling such as industrial fumes, dust, pollen or bird droppings without attacking the protective surface layer of the metal.

We encounter metals in a wide variety of forms in everyday life – from shiny stainless steel cutlery and robust aluminum fittings to decorative copper and brass objects. Each type of metal has its own special features that should be taken into account when cleaning and caring for it. Stainless steel, for example, is known for its high resistance to corrosion, but is sensitive to aggressive or abrasive cleaning agents, which can dull the surface. Aluminium and zinc are light and versatile, but tend to oxidize quickly if they come into contact with unsuitable cleaning agents or too much moisture. Copper and brass develop a characteristic patina over time, which many people appreciate – however, if you want to retain the original shine, you should use special, gentle cleaning agents and avoid acidic products. It is also important to choose the right care for tools and fittings made of different metals in order to preserve their function and appearance in the long term. Knowledge of the respective type of metal and its surface structure is therefore the key to selecting the right cleaning agents and methods and avoiding corrosion and other damage.

An often underestimated aspect of metal cleaning is subsequent protection. Without preservation, cleaned surfaces quickly become susceptible to dirt again. AcroTec offers special preservatives that leave a protective layer on the metal surface. They make future cleaning easier and prevent corrosion.

When cleaning metal surfaces, it is easy for mistakes to creep in, which can affect not only the appearance but also the service life of the items. One of the most common stumbling blocks is the use of household products or cleaning agents that are not suitable for the type of metal in question. What works on stainless steel can lead to unsightly discoloration or even corrosion on aluminium or zinc. Too much pressure or the use of coarse sponges and brushes can also scratch the surface and thus create areas for rust to attack. Another mistake is neglecting to dry thoroughly after cleaning – remaining moisture encourages the formation of rust and other signs of corrosion. In addition, cleaning should not be carried out too frequently or too intensively so as not to remove the protective layer of metal unnecessarily. If you pay attention to the correct application and selection of cleaning agents and dry the surfaces carefully after cleaning, you will not only preserve the appearance but also the functionality of your metal objects – and effectively prevent corrosion.

If you want to keep metal façades beautiful and functional in the long term, you should use the right cleaning and care products. The coordinated products from AcroTec offer an effective, gentle and sustainable cleaning solution that prevents corrosion and preserves value.
