If you have a pet in your household, chances are there will be an accident involving him doing his buisness on your carpet. Faeces are difficult to remove from carpet because the stomach acid they contain will usually leave a deep stain. It is important to remove the entire stain, especially if your pet is an indoor pet. Animals tend to remark the same area over and over if they can still smell any trace of their own urine or faeces.
Remove solid pieces of faeces with a paper towel and place them in a plastic trash bag for disposal, or flush them down the toilet.
Make a mixture of warm water and 1 tsp of clear dishwashing liquid. Pour the solution onto the carpet, and scrub it with a scrub brush.
Blot the area as you scrub, because the traces of faeces will rise to the top of the carpet.
Repeat the same process if necessary to remove any leftover faeces. Rinse the area with cold water.
Pour a mixture of one part white distilled vinegar to two parts water and pour it over the stained area if the stain is still obvious.
Blot the area and check for a remaining stain. If there is still a stubborn stain left behind, repeat the same steps until the stain is gone.
