Title: Another oxalic question
Post by: Dallasbeek on March 23, 2016, 04:59:52 PM
Barkeepers Friend, a household cleaner, contains oxalic acid.  It's good for cleaning all kinds of things without being abrasive.  Does anyone have an idea what the concentration of OA is in it?  The packaging doesn't give a clue.

The package needs to be 100% oxalic acid, not some mixture of things of which one is oxalic acid.  it is usually sold as wood bleach.

If you want some good stuff, search eBay.

Thanks.  Not a high percentage, but it does a good job at removing rust and cleaning stainless steel and such.  I had thought it might be a higher percentage of OA than that.
