Conclusion Why did we get these results?
Foam anti-bacterial hand sanitizer was alcohol based so it may have evaporated instead of actually fighting the bacteria. Dish soap was thicker and more concentrated, so it likely remained on the disk longer, prolonging the antibacterial effects. Hand soap was thinner and may have lost effectiveness after a while. Suggestions for future research on this topic. Testing the effectiveness of the removal of bacteria instead of the prevention of bacterial growth after product use.
