Scientists in the US claim to have developed a self-cleaning lavatory after developing a coating said to repel even the most notoriously clingy “Type 6-ers” on the Bristol Stool Chart.
Their system, which they have described in the journal Nature Sustainability, employs nanotechnology to ensure everything flushes down smoothly. And they estimate it could decrease the amount of water used in lavatories by 90 per cent.
The new material trades under the name Spotless Materials and can be applied to ceramic surfaces in two layers. The first bonds to the material, producing fine hairs. The second is a lubricant, that needs to be reapplied every 500 flushes. Together, they help solve the slipperiest problem in science.
