How To Remove Stains From Granite Countertops

GRANITE STAIN REMOVAL GUIDE – HOW TO REMOVE STAINS FROM GRANITE COUNTERTOPS

(United Granite, and Fairfax Marble) 

 

Stains are discolorations, or dirt, or patch marks on the natural stone that cannot be easily removed.  It is common for natural stone to become stained, especially if it is not sealed well, or if it is a very porous stone. Liquids can get in the stone but there are ways to remove liquids from stone. We will go over different stain removal methods in this article.

 

It is important to determine the situation before doing any work. Is what you have really a stain? What stained the stone? And what type of stone you have? Answering these questions will determine the methodology to be used to remove stains from your stone.

 

Etching

 

Etching often gets confused with staining. Etching is when a stone loses its polish in some areas due to contact with acid and sometimes even water.  Marble and Quartzite are the stones that are most prone to etching. Granite is a harder stone so it usually does not become etched. Limestone, soapstone, and travertine usually come in a honed finished; therefore etching is not an as big an issue for these types of stones.

 

In the photos below you will see some etching. What differentiates etching from staining is the coloring. An etched area is not colored, it just looks like a lighter spot. We will not talk about etches in detail in this article, but I will still give a small tip on how to repair etching on natural stone. Miracle Etch Remover works for most of small etches in natural stone. You can order miracle etch remover from amazon and many other online sources.

 

 

 

Blooming – Green Stains

 

Green discoloration on the stone is referred to as blooming.  Blooming is common in light color granites. It is common that these green discolorations appear on the stone within a few weeks after the installation. What causes blooming is the chemical, CH Glue, Chip Repair Kit, that is used to repair natural stone. The accelerator of this chemical reacts with the stone causing the area to turn green.  Regular stain removers work for most of these green stains.  I recommend Bellinzoni Mangia Macchia Stain remover. Read the stains section to see how Mangia stain remover is applied.

Another option is Blue be Gone.  You can order Blue Be Gone from Braxton Bragg. 

 

 

All Types of Stains;

 

I recommend trying Bellinzoni Mangia Macchia Stain remover for all types of stains. This stain remover works for almost 70 % of all the stains. It is easy to apply, easy to order, and does not cost much.  You can order this stain remover from Regent Stone Products

 

Application is quite easy.

·         Clean the stained area thoroughly using water or lacquer thinner

·         Cover the area using stain remover poultice. Make sure to create a thick layer in the stone (1/4” will do )

·         Cover the area with plastic

·         Take out the plastic after 3-4 hours (do not remove the poiltice)

·         Leave the poultice on the stone until it is completely dry. Usually another 12-24 hours.

·         Clean the area to see if the stain is gone or if there is any improvement.

·         Repeat all the steps again if the stain gets lighter but still not completely out.  

Some staines take more than one time application. The stain removal process takes patience, and research.

 

 

 

 

 

Try following methods if Mangia stain remover does not work.

 

 

Red Wine Stain

 

Mix OxiClean with water and apply on the area. Let it dry for several hours. Remove the poultice after it is completely dry. You may need to repeat the process several times depending upon how bad the stain is.

 

Coffee Stains

 

Place paper towels on the stone. Pour some Clorox bleach on the paper towel. Wait until it is dry. The process may need to be repeated again.

 

 

Ink Stains

 

a)Light Color Granite

 

Mix talcum powder with hydrogen peroxide to make a poultice. Follow the same steps as removing stain using Mangia Stain remover above.  

 

b)Dark Color Granite

 

Mix Acetone with talcum powder to make your poultice.  Follow the same steps as removing stain using Mangia Stain remover above.  

Try mixing mineral spirits with talcum powder if above methods to not work.

 

Oil Stains

 

a)      mix acetone with baking soda, or

b)      mix paint thinner with baking soda

c)       water with baking soda

Use one of the above to make you poultice. Apply the poultice on the stone using the same steps as applying general stain remover as mentioned above.

 

 

Paint Stains

 

Cleaning the stain with Lacquer Thinner will remove most paint stains.

 

Rust Stains

 

Rust stains can be removed by using professional grade rust removers. I recommend HMK Rust remover for natural stones. You can buy rust removers from Stone Boss

 

Be careful using rust removers on the natural stones as rust removers contain acids and make react with your stone causing etches. Test the rust remover on a sample before applying on the natural stones.  You usually see bubbles if the rust remover  is reacting with your stone.

 

 

Biological Stains (mildew, fungi, etc)

 

You can directly clean these types of stains using water. Adding a little bleach into the water will ease the process

 

 

Supplementary Tip

 

For stubborn stains, place a wet towel on the stain, run the iron on it with full stream. This will ease the stains before you apply any kind of stain remover poultice on. 

 

 

 

 

 

DISCLAIMER:  These methods area based on our experience. We cannot guarantee that mentioned stain removing methods will work as each stone is different. Always test the products in a small sample before applying it to the stained area. Some of the chemicals mentioned on this article may damage natural stone. We cannot be held liable if so happens as testing is required first.
