Does the racedeck impact acoustics, as in deaden sound and stop echoes?

I have a finished 36 x 50 garage. Every year at Christmas time I clean it up for a couple parties of ~ 50 people. Noise is an issue with a bare concrete floor. I could carpet it, but that would defeat the easy clean up when kids spill things.

Also would cleaning the racedeck with a power washer:
be safe on the racedeck?
dry in a reasonable time?
be clean enough to eat in the room?
