someone told me that I can strip zinc in a plastic tub filled with vinegar?
I know vinegar has lots of uses, but is this so? -- ---=««-Dilbert Firestorm-»»=--- Zizzle that Fire - it's Zizzle Time !!!!!!! |

Vinegar will etch the galvanized coating, but I seriously doubt it'll "strip" it. Not strong enough.

If it is just so paint will stick and not peel, a full cycle through the dishwasher or soaking in a pan with hot water and dish machine soap will do the job. Colbyt |

I know vinegar is really good at cleaning metal. When I work on old things (e.g., cameras) with schmutzed or hazed brass or chrome parts, I throw them (the parts, not the camera) into a vinegar bath.

The stronger dish machine soap along with the hot water removes all oils left over from the manufacture. It also tends to dull the surface so that paints sticks as well as paint can stick. The process is about the same as a years exposure to the elements which is about how long you wait if you want paint on metal flashings to adhere well. Colbyt |

I believe the instructions went like this, stick the plates in the dishwasher, after the soap and rinse cycle, dry them and scuff/scratch the zinc off with some type of rough pad. -- ---=««-Dilbert Firestorm-»»=--- Zizzle that Fire - it's Zizzle Time !!!!!!! |

As nasty as this stuff is, its amazing how much damage its corrosive fumes can do. Well obviously you don't want to breathe in the vapors, or get it on your skin. I do it outside, and stay upwind. Chemical gloves, a mechanics suit, safety googles and a face shield are necessary, and make sure you are not near an open flame. Have a box of baking soda nearby for spills and cleanup. I put the part to be de-galvanized into a plastic container, and use a chip brush to apply the acid. As the procedure continues, you will need to add more acid, as you end up converting the Zn into a ZnCl solution, and releasing H2. Like most things, once you have the setup it is a relatively simple prodecure, and kind of fun. Jon |

Vinegar will etch the galvanized coating, but I seriously doubt it'll "strip" it. Not strong enough. (Well, maybe if you leave it in for like two weeks or something.) Oh, it will just fine. I built some structures this past year using Unistrut for parts of them, and needed to strip the ends for welding. Vinegar strips the zinc plated ones overnight, and the galvanized ones take a day or so. do you how baking soda figure into white vinegar? I've seen comments where they say after the zinc is stripped from the metal, neutralize it with baking soda and wash it in soapy water and rinse it in fresh water & dry. whats not clear from the comments were, are they neutralizing the vinegar acid or the metal or both. -- ---=««-Dilbert Firestorm-»»=--- Zizzle that Fire - it's Zizzle Time !!!!!!! |

It was referred to as "pickling" to allow the paint to stick to galvanized gutters. |

Jon you can make a faux volcano out of this stuff. it just foams over almost like lava. however, I'm not sure what happens if you keep adding baking soda to the mix. -- ---=««-Dilbert Firestorm-»»=--- Zizzle that Fire - it's Zizzle Time !!!!!!! |
