Using Tools to Remove Dirt


2
Clean the quartz with a fabric gun. A fabric gun or spot cleaning gun can shoot water at the quartz at high pressure to help remove dirt. These are used in dry cleaning for removing stains and are available for less than 75 dollars. This works well for cleaning small amounts of dirt off of quartz that is in hard to get to areas. The fabric gun shoots a small amount of water at a powerful rate.

Make sure to wear glasses or protective goggles while doing this to avoid getting rock specimens in your eyes.[2]


1
Rinse the quartz off with a power washer. If you have a large amount of quartz with a heavy amount of mud or dirt on it, you can try to rinse it off with a power washer. Set your quartz on the ground (preferably on concrete or asphalt) and rinse off the dirt. Using a power washer is more efficient, but you can also use a hose. You can also go to a coin operated car wash and wash your quartz there with their pressure washers. After you wash it, let the quartz dry out. Repeat the washing process until the quartz is clean.

If there is only a small amount of dirt left on the quartz after rinsing, try scrubbing it with a brush and liquid detergent soap and water.[1]


2
Get oxalic acid. If the Waller solution does not work, you can use oxalic acid to clean quartz. You should be very careful with it because it is toxic. Make sure to wear gloves, protective eye gear, and to not inhale the oxalic acid. Make sure to use the oxalic acid outside where there is ventilation. There are other chemicals you can use instead of oxalic acid to clean quartz, but they are more dangerous.

You can usually find oxalic acid for sale in hardware stores.
Use technical or industrial grade oxalic acid because it is less expensive than pure oxalic acid.[13]


3
Scratch off dirt with a knife. If using water does not remove all the dirt from your quartz, you can try to scratch dirt off with a blade. Quartz is harder than a knife, so you won’t scratch the quartz. Using a binocular, microscope, or magnifying glass when doing this. Scrape off as much of the dirt as you are able to.

Be very careful when doing this, the blade may slip and cut your hand.[3]

QUARTZ:

Quartz is an engineered material produced by blending natural minerals with a small amount of synthetic polymer. This combination creates a material that is less porous, more flexible, and more consistent than any natural stone. It is also as strong and difficult to scratch as many granites. In short, Engineered Quartz makes for an extraordinarily reliable kitchen or bathroom countertop.

Today’s quartz products are constantly evolving, with new colors and patterns arriving on the market regularly. Because quartz is synthetic in origin, it can be reproduced perfectly. This means that if you install a countertop in one area of your home and then later want to install that same countertop in another area, you can readily do so with quartz. This is not always the case with natural stone, since no two are ever quite alike.

What’s the catch?

Quartz doesn’t do well with extreme temperatures, so it’s best not to place very hot pans or trays directly on top of a Quartz countertop. Anything under 300 degrees Fahrenheit is fine, though. Also, some Quartz is not perfectly resistant to UV radiation, and will change color over time if used in say, an outdoor kitchen.

But if you want an attractive, consistent, modern countertop that requires no sealer, can be cleaned with simple soap and water, and that can be repaired or replaced with ease in the unlikely event that it ever becomes damaged, then Quartz is the right countertop for you!


5
Try an air scribe. You can also clean quartz with an air scribe (a tiny jackhammer that is powered by compressed air) instead of an air abrasive tool. These remove chunks of dirt and material that might be stuck on your quartz. Air scribes often take only a few seconds to clean an area, rather than minutes or hours.[8]

Air scribes are very efficient, but can be more expensive.[9]
Cover your eyes with goggles or glasses.[10]


4
Dispose of the oxalic acid very carefully. Do not throw oxalic acid down the drain. Neutralize your quartz with limestone chips. You can leave this neutralized solution around (somewhere safe) and add more oxalic acid to it later if you need it again. You can also let the solution evaporate.[15]

Using Chemicals to Remove Stains

Quartz is a mineral that is used for making jewelry, counter tops, and glass. You might have found quartz outside that you want to clean or you might need to clean a large amount of quartz that you mined. You can remove dirt and stains from quartz using tools (such as a power washer and air abrasive tool) or using chemicals (such as the Waller solution and oxalic acid).


4
Use an air abrasive tool. An air abrasive tool will shoot something at the quartz at a very high pressure to remove the dirt. Use something in the air abrasive tool that is not going to damage the quartz. Instead of using other quartz or garnet sand, use tiny glass beads to clean the quartz. This will help prevent damaging the quartz and removing the shiny surface.[4]

You can purchase air abrasive tools online or at hardware stores, such as Harbor Freight Tools.[5]
Air abrasive tools range in price from around 20 to 90 dollars.[6]
Wear protective eye gear when using an abrasive tool.[7]


1
Try the Waller solution. Before trying harsh chemicals on your quartz, try the Waller solution method first because the chemicals in the solution are easier to obtain and are less harmful. You can buy the chemicals and mix them yourself or purchase Super Iron Out at a regular department store (such as Walmart).[11]

Put the quartz in the solution outside because the solution has a strong smell.
The solution only lasts for 24 hours.
Make the solution at home with: 8.4 grams of Sodium Bicarbonate, 17.4 grams of Sodium Dithionite, and 5.9 grams of Trisodium salt of Citric Acid (sodium citrate).
Make sure to wear eye goggles and gloves when using the Waller solution.[12]
