How To Clean Dog Diarrhea Out Of Carpet. With the use of either a vacuum or a steam cleaner, dog diarrhea present on your carpet will get off within no time. Start by mixing ½ tablespoon of dishwashing liquid like dawn and 1 tablespoon of white vinegar into 2 cups of warm water.

Once the cleaning process is complete and the carpet is thoroughly dry, sprinkle some baking soda over the stain, allowing it to rest on the surface for a minimum of 24 hours. The diarrhea stains should gradually disappear now. Use the spray bottle to fully saturate the affected area.
