How to Safely Remove Water Spots from Quartz Countertops
How to Remove Hard Water Spots from Quartz Countertops
Hard water stains and hard water spots are common in kitchens, but difficult to clean from stone surfaces. To simplify the process and keep your quartz countertops safe and protected, we will explain what causes hard water stains, the "Do's and Dont's" of removing them, and how to prevent them in the future.
Please note that removing water spots from granite countertops or composite granite sinks requires a different (and simpler) method.
What Causes Hard Water Spots?
Hard water spots generally show up around the sink and faucet areas on kitchen countertops. They are composed of mineral deposits such as calcium or limescale, and appear as chalky stains that won’t wipe away.
When cleaning with water, the water evaporates, leaving leftover minerals. These minerals bond to the surface, building up into deposits. These marks still occur even with a water softener; softeners just create a softer form of hard water.
Quartz-Safe Cleaners Can Not Remove Hard Water Spots
Quartz countertops are combined with acid-sensitive resins during their manufacturing, meaning they are vulnerable to chemical damage. This causes acidic products such as vinegar, lemon juice, or acidic cleaners to eat through the resins, "etching" the surface. As a result, quartz requires pH-neutral cleaners.
Hard water spots, unfortunately, can not be removed by pH-neutral cleaners. Although certain cleaning products specialize in removing such deposits, the large majority of them are acidic or alkaline-based. This is why prevention is key.
With this in mind, here is our list of guidelines for removing hard water spots and mineral deposits from quartz countertops:
How to Clean Hard Water Spots
Use grade #0000 super-fine steel wool to remove light water spots
For heavier spots, Carefully use a new, sharp straight-razor or scraper.
Take preventative measures to prevent water stains and mineral deposits from building up
Don’t use aggressive/strong cleaners on your quartz or granite countertop
Don’t use vinegar or lemon juice, they can etch your surface
Don’t use non-neutral household cleaners on your quartz
Don’t use water and dish soap to clean your quartz, as they can lead to more water spots, mineral deposits, and soap-scum build-ups
The easiest method of removing hard water spots from quartz is to use Super-Fine Steel wool (#0000 grade). Begin in an inconspicuous (hidden) area, buffing the surface in a circular motion. Ensure the area is undamaged, and proceed to mimic the technique along the water spots. This should be enough to remove light mineral deposits from the surface.
If heavier deposits exist, it may be best to carefully scrape them off of the surface with a straight razor.
Preventing Water Stains and Mineral Deposits
Removal is difficult, so prevention is key.
Many individuals clean their countertops with soapy water, but this should be avoided. Like washing glass with a soapy ret wag or sponge, doing this to your quartz can create a cloudy haze over time. This is because often times the water will dry, leaving leftover minerals or soap-scum.
For this reason, it's recommended to utilize a pH-neutral cleaner that is formulated for your surface, or to use a product designed for preventing water spots.
Although quartz must be cleaned with pH-neutral cleaners, it is worth noting that pH-neutral cleaners can not remove water spots or mineral deposits, nor can water and soap. For this reason, it is beneficial to consider ioSeal-containing treatments, which can defend against deposits and common issues such as staining or fading.
We hope this information has served well to clarify and simplify cleaning in the future.
