Although I am absolutely not "eco", I clean for years delighted with Vienna lime (powder), however, has in the powder always bothered me that one a long time have to rinse to remove any powder residue. This is why I bought the liquid cleaner with Viennese lime from an organic supermarket and lo and behold: the cleaning agent residues are removed in a flash and everything is just as clean as with the powder. The advantages of Vienna Lime: Nothing scratched (I even eliminated so that ink residue on the window pane), everything is shining magically clean (even Branded), metal and flash like new and the surfaces are smooth again, so that new dirt or lime not may adhere so quickly. I use the product for the following cleaning work a: ceramic hob, sink in the kitchen, oven + window on the oven, glass panel at the pellet stove (branded spots disappear immediately), sink and bathroom fixtures, paint residues on window panels or even windows, as a joint cleaner, as polish for stainless steel bowls ... that is for all smooth and non-painted surfaces (glass, metal, porcelain ...). Conclusion: Since the agent impurities quickly away, saving time, everything is spotless and the cleaner is sufficient for many months since you only need tiny amounts.
