Do you have to rinse or neutralize?
If you can't fix it with a hammer, you've got an electrical problem
neutralize with a vinegar water mixture of 1 cup vinegar to 1 gallon water is what i use. stronger solution removes the red. rinse first under cold water.
Do you really need the vinegar solution if you rinse with water first? I would think that the water would remove/neutralize the lye.
I know when I used it on mahogany that I had to be careful when I sanded down the grain that was raised so that I did not sand through the color. Did you find that true?
Did you submerge it to treat the inside? Wiping it on worked great for me but I was doing a piece that was accessible.
It is cool to watch the color change. Also like magic.
