Each of these formulas is known as a Carbona Stain Devil, and assigned a number, from one to nine, indicating the broad types of stains it is formulated to remove.

These stain removers are designed for washable fabric only, and should not be used on carpet, upholstery or leather.
Below I give a brief synposis of the nine formulas, what types of stains they are designed to remove, and how to use that formula properly.

Unlike many of the other formulas which should be applied directly to the stain, No. 8 needs to be diluted. You use it by making a stain removal solution of two tablespoons of this Carbona stain remover, along with 2 cups of hot water, and then soak the stained fabric in it for about half and hour, and finally rinse with warm water. You may need to soak a couple of times for particularly stubborn stains.

These stain removers are very difficult to find in stores, at least in my experience. For example, I have never seen them in any of the stores I frequent around my house, such as grocery stores, Walmart, or other big box stores. *** UPDATE - I did recently see them in my Walmart, but just recently.*** However, I am told that they are carried by a couple of stores, such as Jo Ann Fabrics and some Ace Hardware stores.
You can also find then here, on the Internet. You can almost always find them in packs of six, and sometimes you can also find them sold individually. The links below are to Amazon, but they are through 3rd party sellers. If you purchase through them make sure the shipping is not outrageously expensive. I have tried to find links to ones that were reasonable (at least comparatively), but if you can find these in actual stores you will save money in comparison to buying them online, in my opinion.
