    Brass atty / tank info

    Items you would want in a co-op !

    Actually, I don't believe that is the concern especially if you are like me and wash my "tanks" (whatever form they may take) on a regular basis. What is a concern though is that untreated, free machining brass contains lead, which can leech into the juice.

    Notice I qualified that with "untreated" ... if you soak your free machining brass {whatever} in a mixture of acetic acid and hydrogen peroxide, the surface lead is removed. So ... soak your brass {whatever} in a mixture of 2 parts white vinegar (5% acetic acid) and 1 part of hydrogen peroxide (3% active ingredient) for a period of 10 minutes or more ...

    This process was developed as part of the space program (I have a link to the web site on my computer at home).

    Here's the link I was thinking of. A bit more googling will reveal more.

    Well bugger me with a water melon GT Admin. Have you tried that process on an atty that you've then used for juice?
    I ask because I hate machining stainless and quite like brass in every respect by comparison.

    Thank GT, that's awesome info right there. Now can you tell me how to stop my brass dripping attys from tarnishing after five minutes of use?

    I polished mine with Autosol (Supercheap Auto ~$11) and it didn't tarnish with use for at least a few weeks ... but I've since gone with the brushed finish. Just a word of caution, while I couldn't taste it, I made Domo a RDA and she said she could taste the Autosol.

    I will give Autosol a go. The Brasso I tried the other day lasted about 6 hours before it started looking crappy again.
