Cleaning
The air contains minuscule solid particles, such as dust, rust, and aggressive substances including salt and kerosene, which
encourage corrosion and have a negative impact on how the blinds function. External venetian blinds are equipped with
various mechanical parts that must therefore be serviced regularly to ensure long-term use.
Use a soft cloth or non-abrasive sponge to apply lukewarm water with a highly diluted, mild cleaning agent to the slats.
Carefully scrub away dirt. It is imperative that you then rinse the slats well with clear water.
Cleaning agents with alkaline, acidic or abrasive active ingredients and pressurized steam cleaning may not be used!
