The simplest ways to clean carpet stain are usually the old traditional ways. They require more work, but are the most effective. Home made solutions can be cheaper and less toxic than store bought commercial cleaners. The majority of your stains can be handled combinations of what are usually common house hold items.
Water—Your purest and oldest friend. Many stains can be removed with simply water and some agitation with a rag.
Ammonia—The classic and caustic cleaning chemical. Mix some with water for some tougher stains. Be sure to open your doors and windows. You don’t want to be overwhelmed by Ammonia fumes.
Dish Soap—A little dish soap and warm water can make a good cleaning solution too. It works on your dishes, right?
Baking Soda—Our other classic friend. It is used to absorb odors and used to brush teeth. And had been mention in my other post for its ability to release dust and hair in carpeting.
Add it to water and you’ve got a good base cleaning solution.
Club Soda and Salt—This one was new to me. I’ve heard of club soda on stains, but this method involves working in some salt, pouring on club soda, and then vacuuming and rinsing the stain after an hour or so.
Vinegar—Not just for food. Mix some of this water and it is a cleaning solution for all kinds of stains. It is also used to remove odors. Especially cat urine, which is a horrible smell.
