I would prefer a known brass component over a questionable stainless steel component.From John Palmer's book How to Brew.would you recommend a brass fender washer for the inside of the mash tun? I just dont want anything toxic goin in my wort. the washer i have for the inside of the mash tun is not magnetic...
Source:https://www.howtobre.../appendixB.htmlThe above is from the online first edition. If you have the 2nd or 3rd edition, it goes into more detail, I believe.Stainless steel is the first choice, brass would be second. For HLT anbd boiling pots, I use aluminum.zymotCleaning BrassSome brewers use brass fittings in conjunction with their wort chillers or other brewing equipment and are concerned about the lead that is present in brass alloys. A solution of two parts white vinegar to one part hydrogen peroxide (common 3% solution) will remove tarnish and surface lead from brass parts when they are soaked for 5 minutes or less at room temperature. The brass will turn a buttery yellow color as it is cleaned. If the solution starts to turn green and the brass darkens, then the parts have been soaking too long and the copper in the brass is beginning to dissolve, exposing more lead. The solution has become contaminated and the part should be re-cleaned in a fresh solution.

\Thought I said outside. Aside from that I have wort going through a lot of brass in my brewery. I didn't bother pickling mine, if you have cheap stuff from China you might want to pickle per Palmer in How to Brew. Not magnetic makes me think you probably do have SS for the inside washer.Hang around, we really need more brewing posts herewould you recommend a brass fender washer for the inside of the mash tun? I just dont want anything toxic goin in my wort. the washer i have for the inside of the mash tun is not magnetic...

The test I use is to scratch the washer with a drill to break through any plating, then let it sit on a damp sponge overnight. The combination of air and water in a sponge is a pretty aggressive test for rusting.Is there a way to test if the washer I bought is stainless steel?

Zinc isn't magnetic, either......Not magnetic makes me think you probably do have SS for the inside washer....

I was thinking about doing that, if i scratch it would heal it self if it is stainless steal right? I kinda feel like im learning all over again moving to all grain. Thanks again for all the great tips guys.The test I use is to scratch the washer with a drill to break through any plating, then let it sit on a damp sponge overnight.
