If a panel becomes soiled, wipe it off with a soft cloth soaked in clean water and thoroughly wrung out.
If some areas require further cleaning, use the following procedure:
Wipe the soiled area with a soft cloth soaked in a mild detergent (approx. 5 %) diluted with water.
Wipe off the remaining detergent using a cloth soaked in clean water and wrung out well.
Be particularly careful when cleaning shiny surface panels and metallic parts such as plating as they can be scratched easily.
