I have used cornmeal many times on many floors. Caution, a little bit goes a long way.
As far as corn starch, well, corn starch and water (humidity) makes a great glue (google it).
I have never noticed the floor getting noticeably scratched with cornmeal as it is used sparingly
just on sticky spots. Have never noticed any other unpleasant after effects either. But as mentioned
earlier think about the owners of the floor. My knees often remind me of the effects of a sticky floor.
I also recommend using sweeping compound before and after a dance. Before if the floor is dusty
and after to keep the owners happy.

I don't think you should *ever* “put up with” a super-sticky floor. It damages dancers' knees and ankles. If the floor is too sticky to dance on, and the venue isn't allowing any options for fixing it, cancel the dance.

Thoughts from the organizational perspective: Be very, very careful about adding anything to any floor you don't own! A number of dances have lost their venues over issues such as this. Question: is this floor chronically sticky, or newly so? My generic plan of action would go something along these lines: 1. Put up with the sticky floor for the one evening (question for all: What are good dances for a slow floor? I'm assuming heys and whole-set promenades would work better than Petronella/Rory O'More figures). If you're at the hall early enough, you can try mopping particularly awful spots with JUST water. Unless you own the hall or have checked in with the owners in advance, probably best to avoid adding anything to the floor. 2. Immediately contact the owner/rental coordinator for your hall, and let them know about the sticky floor. Try to find out why the floor is not danceable (spills, new finish, humidity...) and find a short-term solution (mopping, adding a tiny bit of dance floor powdered wax, etc). One time, our hall was used the night prior for a party, and sugary drinks had been spilled everywhere! This wasn't the norm and the owners were apologetic. They put a lot of effort into cleaning up, and there haven't been issues since. 3. Make long-term plans for a danceable floor. A local grange coordinated with the contra community on the best way to refinish the floor. We faced a rather pungent month of dancing, but afterwards, the floor was excellent. 4. If the hall is unable or unwilling to work with you regarding the sticky floor, probably best to start looking for a new venue. This certainly isn't a pretty scenario, but the lousy floor will drive down attendance, and adding anything to the floor without permission will certainly put you in trouble with the owners.

Could have sworn it was cornmeal. I'm not the one who usually does it but I think that the people who run our dance use the right thing.
