Using a toilet spray gun eliminates bacterial residue. After daily use, a large amount of bacteria and dirt remain on the bristles of a toilet brush, making it difficult to completely remove even after cleaning. These bacteria thrive in moist environments and can spread to the toilet bowl and other items the next time you use it, causing cross-infection. After use, a toilet spray gun simply closes the valve, stopping the water flow. This eliminates any residual dirt, significantly reducing the risk of bacterial growth and cross-infection, providing more reliable protection for family health.
