Hard water stains or soap scum in the sink, urinals, toilets, showers, bathtubs, etc.
	If the stain is light- Try light acid restroom cleaner with a foam tip (Spartan: Foamy Q & A)
	Spray over the area and let it dwell for a few minutes.
	Gently scrub with walnut or white pad and rinse with
	clean water.
	If the stain is heavy- Try mild acid restroom cleaner such as
	Shooter from Dynamic Chemical Co.
	Apply the chemical to the area and let it sit for few minutes and
	gently scrub with walnut or white pad.
	Note: Shooter or other medium - to - strong acid chemicals
	should not be used on polished stone surfaces. It will
	tarnish the surface.
	Always read the direction on the bottle and follow it.
	If you want to take the safe route, try the Bio Clean
	hard water deposit removers. It is safe to use on glass,
	porcelain, and other items that shouldn't be cleaned with
	harsh chemicals.
	The company that makes Bio Clean also manufactures
	sealers for glass, porcelain, formica, etc.
	Some areas in the grout may need some brushing with
	nylon brush to reach into the grout.
	Rinse off with clean water.
	Note: If the stain is really heavy, you might have to repeat
	several times to clean up to your satisfaction.
	Try using pumice stone (only for toilets, urinals, only)
	along with other cleaning solutions.
