I did some pH and modified Oddy tests with 3M Safest Stripper. The
pH varied from batch to batch, between neutral and acidic (pH 4).
Also, corrosion to the polished copper coupon in an Oddy test was
virulent and quick! I did not test with lead. I suspect from the
plastic containers chosen to package the strippers that corrosion to
iron and other white metals may be likely. I am very interested in
the results of the questioner's study.
