Nano is a type of material with a structure in the form of particles, fibers, tubes or thin sheets with small sizes only from 1 to 100 nanometers.
Nanotechnology is a branch of technology concerned with the design, analysis, fabrication and application of structures, devices and systems by controlling shape and size on the nanometer (nm) scale. In which, 1m = 1,000,000,000,000 nm.
Each microscopic nanoparticle will penetrate into the surface, remove and completely clean the stubborn plaque quickly, returning the surface clean and shiny like new.
