I use HiGloss for several years now and am more than satisfied. The few still I can not quite understand to believe in "miracle", but .... As a cleaning agent highly recommended, concentrated surfactants take all greasy and smoky dirt away effortlessly. Whether this is as described well as the environment I can not say, but in any case I do not need gloves to clean, as is the case with other power cleaners, also aluminum is attacked not gray or otherwise. For the housecleaning I actually only HiGloss, quite Verglauchbar with HaRa but cheaper ;-) I stick to it in any case and hope that the product will be available for a long time.
