Zinc tubs have a very special charm as a garden accessory. They usually serve as flower pots or house a mini pond. But it is precisely these uses that lead to visible soiling after a few years. If you don't want to do without the beautiful garden decoration, read on this page how you can clean your zinc tub in no time at all.
If the zinc tub is only galvanized iron, no abrasive cleaning agent should be used
Check material in advance
Although there is no visual difference, not every zinc tank is actually made of zinc. Those models are actually made of iron, which is only coated with a galvanized layer. You can recognize the dummy by its rusty spots. In this case, you must not use any scouring agents, as these cause permanent damage to the material. Even "harmless" home remedies such as vinegar or citric acid dissolve the protective layer. With galvanized iron, this does not form again. If you don't rub the layer of a real zinc tank too hard, with a bit of luck the material will repair itself.
