DO STAIN REMOVERS WORK?
Laundry is a big part of our lives. We are constantly trying to take unwanted stains out of our clothes. The best way to do that is to find a good stain remover or detergent. The two main classes of these are enzymatic and non-enzymatic detergents and stain removers. The researcher wanted to find out which of these would work the best. The researcher took two separate pieces of a sheet and stained each of them with five different types of stains that would occur in everyday life. The stains were juice, bacon grease, coffee, chlorophyll (to simulate grass), and blood. The researcher washed one piece of the sheet in non-enzymatic detergent and named this her control. The researcher washed the other piece of sheet in the same detergent and put an enzymatic stain remover on it. This was the experimental part of the experiment. The results didn t support the hypothesis. They showed that the enzymatic stain remover did not help take out the stain better than the non-enzymatic detergent alone
