What could be a white powdery substance on the carpet?

Answer by  worker2565 (44)

This could be anything from baby powder, flour, starch, baking soda or anything else with these characteristics even a form of cocaine. It really depends. I would not suggest tasting or trying to smell what this substance is as it could potentially be harmful to your health. I would suggest, however to clean it as soon as possible.

This substance could be residue left behind from a carpet cleaning. If you own a pet, some flea treatments or collars can leave behind powdery residue.
