Cleaning

The frequency of so-called regular cleaning and choice of a suitable cleaning agent depends on the location of the building and the degree of soiling. If aluminium surfaces are exposed to increased levels of moisture and aggressive urban or industrial atmospheres, experience shows that cleaning must be performed more often. Façades should be cleaned at least once a year.

Cleaning must be performed in stages from top to bottom.
The following rules should be observed during cleaning:

Clean profiles by hand. Use a soft sponge or specialised machine (industrial cleaner, foam canon etc.). Do not use high-pressure cleaners and avoid hard scrubbing with the sponge.
After cleaning, rinse the surface as delicately as possible using clean, descaled water systematically and carefully from top to bottom. Otherwise, residue salts, acids or alkalis may lead to corrosion.
Otherwise, residue salts, acids or alkalis may lead to corrosion.
Only use neutral cleaning agents for organically coated aluminium.
Do not use products which dissolve or attack the paint coating, e.g.:
- heavily alkaline products such as potash lye or caustic soda;
- acidic products;
- acidic products;
- abrasive products;

Wipe away excess cleaning water with a sponge or shammy to avoid leaving behind mineral deposits from the water during drying.

To avoid blemishes and soiling caused by gritting salt, we recommend cleaning the façade as soon as possible. Remember to also clean the floor of spray water thoroughly afterwards.

Follow the cleaning and safety instructions from the cleaning agent manufacturer and test on an inconspicuous section of the item to be cleaned beforehand where necessary.

Cleaning should not be performed under direct sunlight and hot surfaces in sunlight should not be cleaned. Surfaces that dry too quickly can lead to the build-up of blemishes.
