How to Deal with Stains on Granite

Dealing with stains on granite countertops is often both a challenge and a true puzzle. Sometimes people find it hard to distinguish a stain from damage to the stone, but this is essential if you want to find the best way to clean your granite. The next step is to make sure what the reason for the stain is so that you can choose the suitable materials to use against it.

Granite stains are best removed with the help of a compress that usually consists of:

1) absorbent – a paper towel, talcum powder or diatomaceous earth.

2) a chemical – to actually remove the stain.

Different chemicals should be used to make a poultice for the different stains. For stains caused by coffee, tea, soda, mustard or other organic materials, hydrogen peroxide is the chemical that you will have to use. Inorganic stains like ink, dirt or dyes should be treated with rubbing alcohol (for the ink) or hydrogen peroxide again. Oil stains can be cleaned from your granite countertop by using pure acetone. Nail polish remover is not a good idea as its detergents vary depending on the brand and may harm the surface.

When you have finally understood which materials are suitable to handle your stained granite countertop, you should start the cleaning process by testing a small area of the granite that is unseen. You surely do not want to damage its surface by getting to cleaning directly. Once you are sure that there will be no adverse effects to the stone, go ahead.

Your first step should be to mix the poultice which has to look like a thick paste and it should be as dense as cement. An example compress is a mixture of talc powder and hydrogen peroxide. Once the cleaning poultice is ready, apply it to the blemished area and watch out to cover only the stain. Try to make a layer of the mix ¼ to ½ of an inch thick. Leave the poultice over the stain covered with plastic wrap for about 24 hours. Tape the edges down to ensure better coverage. The next step is to remove the wrap. Let the mixture remain in its place until it dries out completely. This may take from a few hours to a day or two, so be patient and wait until the paste is perfectly dry. Scrape away the dry poultice with the help of a plastic scraper and wipe the remainders away with a clean rag. Then give the area a normal cleaning and dry it with another dried and clean cloth. In case there are still some remainders of the stain over the granite, repeat all the steps from 2 to 5. Do not be afraid of doing this several times, especially if the spot is oily. Each time the stain will be going smaller and smaller.

If your granite countertop has darkened or lightened its colour due to water spills, your problem is temporary. When water is absorbed into the matter, it may look like a stain but it is not. Your granite’s colour will be back to normal as soon as the water evaporates. However, you can easily prevent such absorption by sealing the surface of your countertop with a quality sealer. This will also reduce very much the granite’s chance of getting stained and thus spare you a lot of cleaning.
