I think the sodium silicate is acting to reduce undercutting.

Could you explain? I don't see why there would be undercutting since
the work piece is the cathode. Detergent action could be a possibility.
I have yet to understand why it works but I'd like to.

I found the formula in library book over 40 years ago. I tried it along
with several others for cleaning prior to plating and found that formula
worked best of those I tried.
