What Are Hard Water Stains?
Hard water contains calcium and magnesium ions. Hard water stains occur when hard (mineral-rich) water evaporates, leaving a grimy residue on your surfaces. Most commonly, you’ll find hard water stains in the bathroom on glass, porcelain, tile and metal surfaces.  Our region of the country is considered to have moderate hard water.


Granite, Glass, and Fixtures
Try A-maz on granite, glass, and metal fixtures.  Most hard water stains are easily removed from these surfaces using A-maz.  The best part about A-maz is that it’s much safer than most touch cleaning products, requiring no gloves or masks during use.


Ceramic Tile and Grout
Try CLR on durable surfaces like ceramic tile.  This product is highly acidic, and should NEVER be used on natural stones.  Follow label directions for protecting your skin and airways.


Natural Stone
Natural Stone is the most difficult surface from which to remove hard water stains.  Marble and Travertine are two popular natural stones for showers, counter tops, and floors.  Because these stones are Calcium based instead of Silicate based, they are very soft and porous, and this allows the hard water minerals to set below the surface of the stone.  Aggressive acids like CLR not only dissolve the hard water deposits, they also dissolve the stone surfaces.  This can leave a dull surface and create deeper micro-channels for future mineral deposits. In rare cases you may achieve results with A-maz, which is safe to use on natural stone.  Unfortunately, most times replacement is the best remedy for hard water deposits on Calcium based stone.


Identify Your Surface
Not sure if you have a natural stone surface?  Silicate based stones (Granite, Quartz, Ceramic Tile) are non-porous.  Calcium based stones (Marble, Limestone, Travertine) are highly porous.  Simply drop a small amount of water on the surface of the material you are testing.  If the water absorbs into the stone within 10 minutes, you most likely have a porous Calcium based stone.  If the water is still sitting on the surface, unchanged in 10 minutes, you probably have a Silicate based stone.  Remember, never use acid cleaners such as CLR on a Calcium based stone.


Speed Up the Cleaning
If you have large areas affected by hard water stains you could spend hours trying to clean them up.  Use drill pad attachments and a cordless drill to really save yourself some time.  Drillbrush.com.
