If they aren't terrible, baking soda sprinkled in the carpet then set and vacuum up. If more severe, a carpet cleaner using a white cleaning vinegar solution. If that doesn't get it, you might need to have them professionally cleaned.
Steam clean them..............Use Febreeze on them or Shake and Vac, or all three.
Best of luck........Or visit Pet store they may have something........
Hi Sally. I'm Cindy. Sprinkle baking soda liberally on the carpet. Keep your pets off while you do this. Allow it to sit overnight. In the morning, vacuum it up. Then let your pets back in.
Hi Sally, hope these help you out,
Get an enzyme cleaner from the pet store!
