Cleaning pad dulls granite finish...What do i do now??

By Karen Youso , McClatchy/Tribune News

QI used a Magic Eraser on my granite countertop and it appears that I rubbed off the glossy finish. Is there anything I can do to repair the finish or do I need to have a professional look at it?

AUh-oh. Those magic cleaning pads -- they just use water, no detergent or cleanser, to clean -- remove dirt, grime, crayon marks and food stains, all right, but they rely on ultra-fine abrasion. Not exactly sandpaper; they're made of melamine resin foam. The pads cannot be used on surfaces that can be scratched or damaged, such as granite.

Talk to the granite supplier or installer for suggestions on how to restore the granite's surface.

QWhy does my new water heater make the water smell of sulfur? We had it installed and then left for vacation only to return to stinky hot water.

AThe rotten-egg smell comes from hydrogen sulfide gas dissolved in the water. Concentrations of as little as one part per million can result in this odor.

For odor to develop in the water heater, there must be:

--A high concentration of sulfate in the water source.

--Little or no dissolved oxygen in the water.

--Sulfate-reducing bacteria within the water heater. (This bacteria is non-toxic to humans.)

--An excess of active hydrogen in the tank. This is provided by the cathodic action of the anode, a metal rod inside the tank that protects against corrosion.

With these factors present, the hydrogen and sulfur combine to form the hydrogen sulfide gas that gives the rotten-egg odor to the water. Active use of the water heater will reduce the problem, but idle water heaters (during vacations) will allow the accumulation of this hydrogen sulfide gas and aggravate the odor problem.

Smelly water can most easily be eliminated or reduced by replacing the anode with one of less active material (magnesium to aluminum) and then chlorinating the water heating system.

Do not remove the anode; that would leave the tank unprotected. Although it will not affect safer heater operations, it does shorten its life. This is because the anode acts as a sacrificial rod, thus slowing the corrosion process. By removing the anode you will void any warranty on the water heater.
