What chemical property or ingredient allows club soda to get wine
stains out of of a tablecloth?

Hello dottie27-ga,

It's the Carbon Dioxide (CO2) in the club soda that allows it to
remove stains.

Reference:

American Chemistry Council, ChemEcology Magazine, June 2001, “Seeing
Spots? Taking the Pain out of Stain Removal”, By Melissa H. Jackson

“Another option with a fresh stain such as grape juice is the old
standby, club soda. Pour club soda over the stain and blot. The CO2
bubbles in the soda break up the long-chain organic molecules that
hold the stain together, and the resulting water-soluble fragments
wash away with the soda.”

Good luck with your project.
