Cleaning With Lemon Experiment
Many people use lemon juice to keep household items smelling fresh and looking clean. Does lemon really have any cleaning powers?
Can lemons be a cleaning agent?
- 3 ripe lemons
- Lemon juicer
- 3 pennies made before 1982
- Greasy pan
- Sink with metal plug
- 1/8 cup measuring cup
- 4 dry cleaning rags
- Take a ripe lemon and cut it in half.
- Squeeze out the juice, and then put the juice through the strainer to make sure that there is no pulp left. Do the same with the other lemons. Make sure that you have about half a cup of lemon juice.
- Divide the lemon juice into four parts, about 1/8 of a cup each.
- Now, place three pennies into a cup with 1/8 cup of lemon juice. Set this aside.
- Plug your sink and place another 1/8 of a cup of lemon juice into the sink.
- Dip the brush into another 1/8 cup of lemon juice and paint it onto part of a dirty bathtub.
- Get a small greasy pan and place another 1/8 of a cup of lemon juice into the pan.
- After 10 minutes, use a cloth to rub at each of these materials. What happens to each of these materials when they’re exposed to lemon juice?
The lemon juice will clean the pennies and soap scum and will not work as well on the grease.
