An oil-based stain will darken the stone and normally must be chemically dissolved so the source of the stain can be flushed or rinsed away. Clean gently with a soft, liquid cleanser with bleach OR household detergent OR ammonia OR mineral spirits OR acetone.
Organic stains – make a poultice with one of the powdered poultice materials and 12% hydrogen peroxide solution, or you may use acetone instead of the hydrogen peroxide. Oil-based stains – you should make a poultice with baking soda and water or one of the powdered poultice materials and mineral spirits.
Next, mix equal parts bleach and water in a bucket. Once the bleach has been diluted, pour it onto your slabs and leave it to sit for 15-30 minutes. You can then start to brush the surface or, use a power washer to ensure there is no bleach residue left over that could stain the paving.
If you want to attempt to remove product residue or hard water build up yourself, spray the stone with a pH-neutral, stone-safe cleaner and allow ample dwell time to soften the residue. Then using gentle pressure and a white Scotch Brite pad or a Dobie pad, clean the stone.
Clean stone surfaces with warm water and a mild soap such as a clear Dawn Liquid Soap. Do not use products that contain lemon, vinegar or other acids on marble or limestone. Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth. Change the rinse water frequently.
If you have natural stone tiles anywhere in your house, avoid cleaning them with vinegar, lemon, or ammonia. The acidity in the products etches and dulls the stone, says Elena Ledoux, owner of Superb Maids in Las Vegas, Nevada. To repair, it will require a very expensive re-polishing process.
There is a misconception that stone stains easily. It may stain easier than ceramic or porcelain, but timber would have the same issues. It's like if you drop something on your carpet, you will clean it up quickly so it doesn't soak in and stain. The same concept applies for natural stone.
Natural stone (with the possible exception of soapstone) is considered a porous material. This means that it can absorb moisture and liquid. Any absorbed moisture can cause discoloration in the stone. This discoloration is a stain.
It is common to mix bleach with water; however, you can also add other ingredients to make it more effective. Similar to cleaning pavers with muriatic acid, avoid an intense concentration of bleach, as it can damage the pavers.
Acidic commercial cleaners and those containing harsh chemicals, like bleach, can damage and dull natural stone surfaces.
We also NEVER recommend using OxiClean or Mr. Clean Magic Eraser as a cleaner on any type of natural stone.
Apply a paste of baking soda and water over the stain and leave it for 24 hours. Gently scrub the area and rinse it with plain water. Stains on Sandstone pavers, Travertine floor tiles, and Marble floors can easily be cleaned with a baking soda solution.
Put a little household detergent onto the sandstone (being sure to follow the manufacturer's instructions in case you need to mix it with anything) and scrub with a hard bristled brush in a circular motion until you can no longer see the oil stain. To finish, you will need to carefully rinse the stone.
Vinegar is low on the pH level, which makes it acidic, and we already mentioned that baking soda is caustic, thus resulting in a volatile combination for porous stone surfaces. On dark slate, for example, this mixture will leave a stain that looks like a discoloration spot.
DON'T: Use harsh or abrasive cleaners and sponges.
Windex; acidic cleaners, like vinegar, lemon, lime; or anything with ammonia or bleach should be avoided. Frequent use of these chemicals will dull and weaken the sealant over time.
The simplest answer is no, it is best to avoid bleach when cleaning any type of natural stone. Many home cleaning products, particularly bleach and vinegar, are too harsh or acidic to be on natural stone. These cleaners strip down the stone and leave it in a weak, damaged state.
It's recommended to use a dust mop to clean your natural stone floors and countertops daily, or every second day. You can also use a vacuum cleaner instead of a dust mop. Also, you should use a neutral cleaner weekly to wash your stone floors.
The Difference Between Manufactured Stone and Natural Stone
Natural stone is heavier in weight, making it difficult to transport. Manufactured stone requires less installation time while also being cost-effective. Manufactured stone creates less waste than natural stone. Manufactured stone adheres to multiple surfaces.
Clean stone surfaces with a few drops of neutral cleaner, stone soap (specific products from Lithofin for example), or a dishwashing detergent and warm water. Use a clean soft cloth for best results. Too much cleaner or soap may leave a film and cause streaks.
And in this case, this mixture does not work well with the natural stone countertops. Due to the fact that vinegar is acidic substance and baking soda is caustic, the result of mixing the two can have an unstable effect on stones that are porous.
Keep It Simple to Clean Natural Stone
You can use any type of mild soap detergent, such as dish or hand soap, and mix it with a little water. Wet the stone first, and then use a bristle brush and soap solution to wipe the stone clean. The last step is to make sure you rinse thoroughly.
Countertops. If you want to keep your stone countertops looking beautiful, don't reach for vinegar. The acid etches and dulls natural stone such as marble and limestone. It can slowly dissolve them, according to Beckman.
