On Shabbos, a container of water spilled on my carpet. Conventional wisdom is to throw baking soda on the wet area to soak up the liquid to protect the carpet from odors (I don't know if it actually works) Is this permitted on Shabbos?
[My thought process regarding the melachos:
Dash: Applies only if you want the liquid. Here, not only do you want to get rid of the liquid but it doesn't look like dash since the water is subsequently absorbed into the baking soda.
Borer: Applies only if the carpet is being "purified". Here, you're mixing baking soda into the carpet.
Libun: The baking soda is causing the opposite.
Lash: I don't think the baking soda forms into one mass, though I've never tried]
