Update: the fan of the outdoor unit of the airco is blown to pieces and I asked the manufactorer by mail if they can supply me with a new one. Haven't heard from them yet...

I waited about 30 minutes and then whiped it all dry. It looked pretty dry already but I did it just prevent any strange blodges or spots. She is starting to shine
