The stained area may feel more like an accumulation of something on the surface of the granite. It may also feel as smooth as the rest of the surface. In this case it is likely a hard water stain and can almost always be removed. The exact treatment depends on the severity of the stain, but in general it can be gently rubbed with an abrasive until it disappears. Before attempting to remove hard water stains on granite, it is best to test the abrasive on a hidden area, to see how it will affect the look of the stone.
How to Prevent Hard Water Stains on a Granite Sink
Granite sinks are prized for their durability. They often provide years of service while maintaining their original beauty and luster. Because granite typically is a porous stone, water might be absorbed and hard water deposits can build up. This might eventually stain the surface of your granite, marring the stone’s natural beauty. Proper care and maintenance of your granite sink often will prevent hard water stains from occurring. This includes preventative steps to avoid stains, as well as sealing your granite sink regularly.
Hard water also forms deposits that clog plumbing. These deposits, called "scale", are composed mainly of calcium carbonate (CaCO3), magnesium hydroxide (Mg(OH)2), and calcium sulfate (CaSO4). Calcium and magnesium carbonates tend to be deposited as off-white solids on the inside surfaces of pipes and heat exchangers. This precipitation (formation of an insoluble solid) is principally caused by thermal decomposition of bicarbonate ions but also happens in cases where the carbonate ion is at saturation concentration. The resulting build-up of scale restricts the flow of water in pipes. In boilers, the deposits impair the flow of heat into water, reducing the heating efficiency and allowing the metal boiler components to overheat. In a pressurized system, this overheating can lead to failure of the boiler. The damage caused by calcium carbonate deposits varies on the crystalline form, for example, calcite or aragonite.
Hard Water Stain Removal Guide: Granite Countertops
Preferable to using chemicals, the ideal way to remove hard water stains from granite countertops is to scrape them away. Using wire wool is an effective tool for eradicating hard water stains from various surfaces in the kitchen and bathroom. Using wire wool is particularly beneficial when used on granite countertops, as it will not damage the surface. Dip the wire wool into some soapy water and carefully rub at the stain until it is finally removed from the surface. Instead of wire wool, a razor blade can be used to scrape away hard water stains. Make sure you are wearing protective gloves and slowly chip away at the stain with the razor blade.
How to Clean Granite Countertop Water Stains
To prevent or minimize these stains, your granite surface should be treated with a high-quality granite countertop sealant that helps stop the absorption of liquids into the stone. Even sealed granite can become stained and need treatment to return the countertop to its original appearance, but there are some precautions that can help minimize damage. Never use common household cleaners that can damage the protective sealant and put your granite at risk for stains and a dull appearance. Clean your counters regularly with a nonabrasive, nonacidic cleaner. Always clean up spills immediately, before the liquid has the chance to be absorbed.
The picture above this sentence is what we'll call "Plan B". It is a poultice, or extractor that is used with covering up the stain area with this applied by a plastic sheet, that soaks up the stain as well as drives any existing stains that are deep in the granite down any further. This leaves a spotless area ready to be resealed. Judging that they are hard water stains, after you clean the hard water stains, test the countertops with a few drops of water. If it soaks into the granite within a minute, you'll need to reseal your granite countertops. Just like any maintenance on an investment, natural stone countertops require sealant at minumum of every few years. The sealers are also available in the same section, same company as you got your countertop "Plan A" cleaner. Spray or wipe on the sealant, and let it set a few hours before usage. That away, you'll never have to worry about having hard water stains really ever again! Prevention is the key after getting these stains out, so sealant is really the answer to never having to do this again, other than routine sealing.
Does Water Damage Granite?
That being said, it is still a natural stone and though tiny, it is porous meaning that liquids can ultimately permeate the surface. The good news is that under normal home conditions with stable temperatures, any water that is able to permeate the surface will likely leave a dark stain, but will ultimately dry.

Prevention of etching involves one rule: Don’t allow acids to stay in contact with the stone. That means avoiding acidic cleaning products. Clean granite with a pH-neutral cleaner such as stone soap or a mild dish-washing liquid mixed with water. Preventing etching also means using a cutting board, chopping block or plate when preparing acidic foods such as tomatoes or citrus fruits. Immediately blot up any spills from acidic foods, flush the area with mild dish detergent solution, rinse the area with clear water and towel dry. Consult a professional stone restorer before attempting to repair etch marks on granite.

A cloudy or hazy appearance to the stone typically isn’t the result of actual damage. This cloudiness usually results from using the wrong cleaning product, whether it’s abrasive or acidic and eating into the surface of your countertop or you’re using a product that leaves behind a film. Sometimes cleaning granite with dish soap leaves a layer of soap film that makes the surface appear dull. Water from a sponge may also have this effect.
This Granite Care Guide Will Keep Your Countertops Looking New For Decades
Granite could damage your knives and dull their blades, so unless you don’t mind replacing or sharpening your knives fairly often, you’ll probably want to cut on a chopping block. Also, most foods release some moisture which can penetrate the pores in natural stone if it’s not properly and thoroughly sealed. So, while you can cut your food right on your countertop, if you want to keep them looking pristine, you should probably use a cutting board just to be safe.
