Tagchen all together here, would even pronounce the manufacturers of this product a very, very big praise. We had bought us about 2.5 years ago a new Bomann GSP 776.1 / 45 cm. Since a few days the jars were after the cleaning cycle only cloudy and dull. So diligently refilled salt and rinse aid for each course, has nothing helped, and the changing the degree of hardness of the rinse aid. By chance we came across this little miracle product, wanted to get the technician allow for fault diagnosis. Hung machine cleaner according to instructions in the machine turned on the hottest gear ... Voila ... spotless clean and very, very gutriechend. Everything is super clean, then there is no dull or milky glasses / cups / dishes more. PERFECT, we will now use the cleaner more often than every 2.5 years for us, the machine still long, for a long time remains. Only recommended ..... forgive hereby officially !! 6 !! STARS !!
