If I were to conduct this project again I would be sure to put the cloth on the colorimeter correctly. If I took the cloth and moved it slightly to the left or right the colorimeter will take a reading that is actually darker than what it used to be. I would also use chemicals that are compatible. The chemcials and solvent I used didn't work well with eachother. Therefore the stain wasn't removed as well.
Most garments are expensive.
If you get a stain on a piece of clothing you shouldn't just throw it away and get a new piece. It's important for dry cleaners to provide the proper treatment to remove stains off of clothing or the result will be that people will have to spend more money buying new clothes than spending money on just getting their stains removed, for nearly half of the price. Soap has existed since colonial times when women made them in large pots. They somehow got the idea to start making soap in large quantities, so they could sell them to other families. The material cotton was made from a cotton plant.
