The idea is based around A Brush (I'm deciding between a toothbrush or maybe some kind of scrub brush or scouring pad), and a bottle of a soapy solution (that refills itself when not in use). When the solution is applied to a surface, and the brush is then used to scrub the surface, it cleans the surface perfectly, including
-Removing stains and discoloration from fabric
-Removing tarnish, and polishing metal
-Killing all bacteria on the surface
-Removing any and all marks and cracks in glass
-Removing any and all dirt from any surface
-Smoothing dents and gouges in metal and wood
-When used on human skin, it removes any skin imperfections such as pimples, warts, and moles, as well as healing any wounds that have been scabbed over (but not open wounds)
Yeah, this actually seems kind of dumb now that I write it down, but what do you think?
