    Bit of useless information to help you all through the day

    The first flush toiet was in vented by an Englishman called Crapper, no bull, true story.
    Vinegar cleans pickling on new galvanized sheets. Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, and aluminum alloys. The pickling is removed so paint can adhere to the sheet metal better.
    It is because vinegar contains a mild level of acid, which effectively cleans the powdery residue on a galvanized surface. Although having steel galvanized does inhibit it from rusting, the zinc in the galvanized layer still oxidizes when it comes in contact with the atmosphere, and forms that powdery surface you could rub off on your hand. Some metals such as aluminum, which doesn't rust but forms a layer of oxidation instead, can't be effectively welded until they are cleaned with a nitric acid solution.
    Another one for you arry, the Doberman dog was a cross between a Rottweiler anf a German Pinscher. The man who wanted it to have the power of a Rottie(love them) and the speed and agility of the Pinscher was Herr Doberman in the mid 1800s.
