The product is also recommended in my view. After descaling the coffee machine I have the (collected) water / descaler mixture used successfully even for descaling of two kettles and some bathroom fixtures. More's were here just not for descaling, but I think I still have the rest after the fourth passage can achieve useful results.
From my side a clear recommendation, even if the product is considerably more expensive than no-name products from the local drug store. The latter, however, have so far never looked so good, and certainly not repeated here.
