| | Abstract | The purpose of the project is to see if bleach can get permanent marker |
| | out of cotton material, and if it can, which strength of bleach will be most |
| | successful. The procedure involved cutting three inch by three inch |
| | squares out of material and putting a line of permanent marker on each |
| | square. It also involved measuring to make sure each container had the |
| | correct concentration of bleach and water in it. One square of material |
| | was then placed in each container and left in and observed for nine hours. |
| | After the squares were removed, they dried overnight and the tensile |
| | strength was tested. The data concludes that none of the strengths of |
| | bleach were successful in getting the marker stain out, and a few of the |
| | squares got ruined by the bleach. In conclusion, bleach is not something |
| | that should be used to get permanent marker stains out of cotton material. |
