The Removal of Permanent Marker
Do different kinds of solvents affect the removal of permanent marker?
The purpose of this research is to find out the most effective solvent that will remove permanent marker from a smooth surface, for example, a silver tray. It was hypothesized that alcohol will be the most effective solvent in removing permanent marker compared to Colgate toothpaste or water. That hypothesis was proven correct because when it was tested alcohol was rated as a three on the color strip, meaning it removed nearly all the permanent marker, leaving very little behind.
The experiment was set up with three silver trays, each with a two inch line drawn on the silver tray. On each silver tray, Colgate toothpaste, water, and alcohol was tested on the permanent marker to see how much permanent marker would eventually be removed after each solvent was applied. Using a dish sponge, each solvent was scrubbed five times (up and down). After the results were shown, each silver tray and how much permanent marker left from the solvents were compared on the color strip.
At the end of the experiment, data indicated that the alcohol removed most of the permanent marker compared to the other two solvents. When water was applied to the permanent marker, the results showed that the effect was not in fact dramatic. The same goes for the solvent Colgate toothpaste.
Based on the results of the experiment, it can be concluded that alcohol is the most effective solvent for removing permanent marker on a smooth surface, like a silver tray.

Alcohol will be the most effective solvent on removing permanent marker compared to water or Colgate toothpaste.
Alcohol was the most effective solvent in removing permanent marker because it resulted as a 3 on the color strip, therefore, removing nearly all the permanent marker. My hypothesis was correct because I stated that alcohol would be the most effective solvent in the removal of permanent marker, and the results shows that alcohol did in fact remove the most and was the most effective solvent in removing permanent marker.
Some possible experimental errors are the possibility of not rubbing the permanent marker off hard enough when each of the solvents were applied. For example, I might have rubbed harder on some solvents, but not as hard as on the others. It would very much have a big effect on the data and results.
I could apply this experiment to my life if I needed suggestions on how I could remove permanent marker on household items. I recommend that this experiment would last more than one day for better and more accurate results.
