The topic of this science fair project was, seeing what stain removers did, and did not work on various stains. People all over the world spill things on their clothing, and can’t get the stain out. This experiment will help people find the correct stain remover, that is efficient and safe.The hypothesis for this experiment was that enzyme stain removers would work better than, non-biological stain removers, and biological stain removers. The approach to investigating this problem was to take one shirt and spread the stain on four different areas of it. Then, spray one to four squirts of different stain removers on each stain.
