Stain Removal From Your Stone Countertop

If your granite countertop has a stain you may be able to remove it yourself. It is a very easy process to do . A few things to think of before you start is to figure out what kind of stain it is. If it is an organic stain then it will be easily removed using this process. Organic stains are those that are not oil based. Coffee, wine, orange juice etc. If it is stained from oil it will not be removed using this process. Please be sure your countertop is granite! this may ruin the finish on marble, travertine etc. If you suspect your countertop was made with low quality granite then do a test area to be sure the process does not ruin polished surface. For more information on chinese granite and how to spot the low quality before it gets put in your kitchen then please check out our website for that info. Next thing to test is whether or not your countertop is sealed properly.  Take some water and sprinkle it on the surface in a few different spots. If it beads on top then its sealed. However if it slowly seeps into the stone and darkens it, that means it wasn’t sealed properly or needs a reseal. Do not seal your countertop before removing your stain. It will seal the stain right in and makes this process much harder. Please follow these steps and repeat if necessary.


Things you will need:


Baking Soda


Plastic Wrap

Masking Tape





After you have cleaned your countertop you will need to mix up a poultice using the baking soda and peroxide. In a cup add making soda first and then peroxide in small amounts until you make a paste. The consistency should be that of icing used for making cakes etc. If it is too wet it will just make a mess, too dry and its useless. Next, Apply the poultice you have made onto the stained area. Apply it 1/4 ” thick and go past the affected area by 1″ or so. After applying cover in plastic wrap. Tape down the edges of the plastic wrap , but leave a 2 inch strip un taped and lift it off the surface so it can allow air to circulate a bit. Don’t touch it!, leave it for 24 hours and then check to see if it is dry. It must be hard to the touch and have no moisture to it. If not dry leave for another 24 hours. After it is completely dry it is time to remove the plastic wrap and wipe the poultice off.  Wipe the area clean with water afterwards and dry with a towel. Inspect the area and determine if the countertops stain has been removed. You may need to repeat this process a few times however the stain will lift.


Once your stone is stain free you must seal the countertops. There is lots of info and a list of products to use on our website.

Now you know how to remove stains from your countertop and how to bring them back to original look. Hope this helps
