Our 1A Clean photovoltaic solar system cleaner concentrate is Swiss-made in Bonaduz and comes in a 10-liter canister. It is easy to apply to glass or plastic coatings and effectively removes dirt without damaging the frames or surfaces. The concentrate can be diluted with water in a ratio of 1:3 to 1:4, depending on the degree of dirt.

To use, simply mix the concentrate with water and spray it onto the surfaces to be cleaned using a foam lance. For heavy dirt, such as burnt-on bird droppings, we recommend using a soft brush. This can help effectively remove even stubborn dirt.
