Cleaning your dirty carpets often involves using a carpet-cleaning machine and expensive cleanup solutions, such as the ones made by Bissell. However, it is possible to make a carpet shampoo that works just as well, and sometimes even better, than those sold commercially. All you need are a few common household ingredients.
Mix together 1 tablespoon of vinegar and 1 tablespoon of castile soap in a small bowl. Castile soap is made out of vegetable oil instead of the more common ingredient of animal fat in most other soaps.
Add the mixed ingredients to a bucket filled with a quart of warm water. Stir the solution to create a small amount of suds.
Pour the solution into the designated spot in the carpet cleaner per the machine's directions.
