Scientists Invent Germ-Repellent Toilet Coating

Researchers from Pennsylvania State University in University Park, Pennsylvania, have invented a new spray-on coating that could reduce bacterial growth on toilets, WallStreetWindow.com reports.

When sprayed on a toilet, the bacteria-repellent coating makes the surface too slippery for any pathogens to remain attached to it for long. Developers tested the coating by applying it to a toilet in a lab, then dumping synthetic fecal matter on the toilet. All the matter slid down the toilet surface without adhering.

Applying the coating is a two-step process. First researchers sprayed polydimethysiloxane silicone, a substance made of molecularly grafted polymers, on the toilet, which makes the surface very smooth once it dries. Next, the scientists applied a second spray of silicone lubricant. This process takes under five minutes and lasts for about 500 flushes before it needs to be reapplied.
