Great for removing fingerprints off walls.

The O Monster Cleaner^® Plus is a foaming all-purpose cleanser that clings and instantly attacks and loosens dirt, fingerprints, smudges, and more from most hard surfaces in your home. The PLUS is the dirt-attacking foam that's fortified with ammonia. It works especially well on doors, door frames, light switches, walls, ceramic and plastic tile, sinks, tubs, showers, counter tops, table tops and also vinyl, leather and plastic surfaces. This all-purpose cleaner does not contain abrasives, so it's safe to use on porcelain bathtubs and sinks. It can even be used to mop floors! Its "Any Which Way" nozzle sprays from any direction (even upside down), so you won't strain your back trying to reach nooks and crannies.
