soap solution

I turn green wood to finish thickness, and let them dry and warp. I use the cheap brown soap. The only thing I have noticed that the soap does for these bowls is make them much easier to sand out. I use Mahoney's Walnut oil for finish, and it doesn't bother that at all. I have used other oils (Deft) for some pieces, and it doesn't bother that either. I don't think it would bother water based finished, but haven't tried it. The soap does leach some colors out of the woods. I keep a tub for the black walnut separate from the others.

The "soap" most refer to in turning is hand dish detergent, which contains an humectant http://en.wikipedia.org/wiki/Humectant like glecer(ine)ol to keep M'lady's hands from drying. Other polyols are also used.
You should have no trouble if you're turning a treated blank a second time, because you'll turn the affected area away, unless you soaked it forever and a day. If you're finishing one which has had only a sanding after treatment, it could present a problem. The finish might refuse to adhere where there is still some present. Rinse well with methylated spirits, what they call denatured alcohol here, or acetone if you get a bad spot. Glycerine boils at >250 C, so warming it won't boil much away.

Thank you, but as I'm using waterbased finish to keep the wood as natural as possible I think I will have a problem. I'll open a new thread to explain my problem: 'steaming wood to prevent cracks and splits and warping?
