"I am thinking about building a valved reflux still and found out brass contains lead, even brass labeled lead free contains lead. There are so many brass water fittings available I was wondering if the amount of lead brass contains is of any real concern.

Thanks,
Yurmo"

Hi Yurmo, A 50/50 solution of water and hydrogen peroxide is used to pickle your brass. Put the parts in the water bring it to a boil and when you brass turns a brighter yellow it's done. Does not take more than a couple of minutes.

Have Fun.

That's the formula I used. But I didn't heat it in any way. Just used it at room temperature for the time that Bushy stated.

Ok, I am in the midst of building a valved reflux as well. My question about this pickled brass. The plans I have state to terminate the copper tubing inside the condensor with compression fittings. But, once together you won't be able to take it back apart. Soooooo, I assume the pickling of the brass only has to be done once????????? Help, totaly confused now.

Yes the picling is only done once. Also a compression fitting can be taken apart, the only part that you can't take off are the nuts that are on the tubeing. That is you can take them off but it will damage the compression nut and also the tubeing.

Thanks Bush for clearing up the pickling. I realize the comp fit can be tak'in apart but with the plans I have once the conden ti soldered together there is no way back to the lower fitting! I'm pickling fo sure. Thanks!"

I already ""pickled"" my brass blow valve and brass plug for my still with boiling half vinegar and half H2O. After reading this thread i decided to do it one more time using 2 vinegar and 1 hydrogen peroxide due to Bushys post. After doing it the second time my fittings turned dark rather then bright yellow. Im assuming its due to the higher acidity, but just to make sure, Is this a bad sign, or bad in any way? thanks guys."

Hi Gibbs, I'm not sure why you doubled the vinegar and I'm guessing that's why your brass turned black. I don't think it will hurt anything but you may want to take some 50/50, h2o-h2o2, cold, and soak the parts in it to see if it will turn back to yellow.

If ur asking why I did the proses twice, I did it because the first time I only used vinegar an water. If ur asking why I used 2 parts vinegar it's because your 2nd post said 2part vinegar an one hydrogen peroxide. Am I missing something? Thanks for the tip"

I see, well I don't think it hurt anything, and it is definitly pickled. The color will darken over time anyway. But if you want it bright and shiny you could try soaking it in straight vinegar, thats what I use to clean up copper and brass parts.
