Carpet stains can be a nightmare, especially if you have pets, children, or messy friends. However, there is a simple homemade solution to remove organic stains from your carpet. This recipe works well for food and dirt stains, but not for ink or dye stains. To make the carpet cleaner, mix water and vinegar in a spray bottle. Spray the mixture on the stain and cover it with a damp rag. Use a steam iron on the rag for around 30 seconds to remove the stain. For stubborn stains, repeat the process. This method is also great for eliminating pet odors.
