There are many ways to clean tile floors. However, some methods help sanitize floors better than others. Two common cleaning methods are analyzed for how well they removed bacteria from tiles.
The first method involves simply cleaning floors with a mop and bucket. The second method tested was the spray-and-vac method. With the mop and bucket method, fresh tap water was added to clean buckets. Researchers then used a clean mop to wash the floors. With the spray-and-vac method, sanitizing fluid is applied to the tiles using a spray gun. After that, a specialized vacuum extracts the fluid from the floors.
Researchers have tested the different methods on grouted ceramic tiles, which are commonly found in many office spaces. After the two separate selection of tiles were cleaned with the two different methods, researchers waited 10 minutes for the floors to dry. Once dry, they collected bacterial samples.
These tests showed that the spray-and-vac method sanitized the area much more thoroughly than the mop and bucket method. The samples showed that the mop removed 50% of the initial bacterial counts, while the spray-and-vac method removed nearly 90%. Even with hospital grade disinfectant applied to the mop, the mop still left behind significant amounts of bacteria.
When the disinfectant was used with the spray-and-vac method, the bacterial count showed only 0.8% at the grout line – this means that the spray-and-vac method was almost 60x more effective than the mop and bucket method! The study also showed that although the grout typically presents the most challenges for disinfecting tile, the spray-and-vac method did not show significant difficulty removing bacteria from the grout.
