How do you get comet off carpet?

Answer 1

If by comet you mean the abrasive cleaning powder, it is water soluble; just wash it. Carpets are not necessarily that easy to wash, however, moisten the comet and soak it up with a paper towel, that should work. If it was "dry" when spilled, just vacuum it up!

Answer 2

To remove comet from carpet, first, scrape off any excess residue with a spoon or dull knife. Then, apply a mixture of water and mild liquid detergent to the area and gently blot with a clean cloth. Finally, rinse the area with clean water and blot dry.
