Hi, regarding getting rid of the galvanized coating. A MUCH safer way to handle this is to let the parts soak in vinegar rather than burning. Several of my local stores carry Gallon jugs of Vinegar and you can strip the Zinc coating safely and easily with this. Just make sure that 1. you do this with excellent ventilation2. there are NO open flames anywhere nearby3. you rinse the parts well4. pour baking soda into the waste Vinegar until it stops fizzing and then dispose of it.So what happens is that the vinegar (an acid) bonds with the zinc metal and ejects hydrogen gas and some vinegar fumes. what is left in the wash is zinc salts (the same kind used in cough lozenges) and the vinegar can be neutralized with some baking soda.
