To find out if this keeps his promises I started a test in my shower; 1) Clean the 2 parts of the sliding glass door and wipe (with the "Microfiber Mop Anti-Limestone (Vileda)" .. for that matter) 2) Spray the product "Magical" and wipe with attached microfibre according to instructions. 3) The next day, test "life-size" First directly with the water jet, but there on the 2 clean surfaces, water slides almost equivalently. Then during the shower, watch what happens; One of the two windows will cloud and humidity ... anyone's guess what the (a clue, I noticed the product 5 *****) Result, cleaning of the wall is much simpler and shower clean.
