[pianotech] bead blasting wood...gently

[Euphonious Thumpe]

I spoke with someone recently who claimed that baking soda, at the right pressure, can safely be used to nicely strip old finishes off case parts. I haven't seen the results, so if you want to try this advise "proceed with caution". But he was a professional cabinet maker, so maybe knew what he was talking about. If it's true, it woud be a real "breakthrough". ( No pun intended.)

I've got baking soda in the shop.  I was going to use it, but decided to take a shot with the fine bead, since I already had that in the sump.

I will say that I had to also be very gentle and careful with the soda on wood, as it is surprisingly aggressive.
