Apply a layer of white toothpaste to the scorch mark and allow it to set for several minutes. Scrub the area lightly with either a scrub brush or toothbrush. Wipe the area clean with a soft cloth and water. If the stain remains, apply some Soft Scrub using the cloth and allow it to set for several minutes.
If this happens, use soap and water first to clean up any soot or other debris. Next, you can make a homemade cleaning solution using flour and hydrogen peroxide. This will make a gritty sort of paste which you then spread over the burn mark, completely covering it.
Once granite slabs have been damaged by heat, they can still be restored to their original beauty. This is most easily accomplished with restoring liquids or pastes. There are special creams and solutions that can be used to polish granite countertops and remove stains and marks.
Granite is naturally heat resistant, and heat damage would occur only if the granite was heated unevenly. So briefly putting a hot pan down on your granite countertop isn't going to cause long-term damage. That said, we don't recommend putting hot pans on granite countertops — not for the granite's sake but for yours.
Again, you can make a paste with baking soda and water. For a poultice to work, however, you need to apply it to the affected area, cover it with plastic wrap (you can tape down the edges if needed) and let it sit for 24 hours. Wipe or scrub the poultice away, and reapply as needed to remove hard water stains.
If the cloudiness is due to a filmy build-up of oil or hard water, simple deep clean with an appropriate granite cleanser. Cloudiness may also mean it's time to reseal your countertops but make sure to do so carefully and follow all instructions.
Make a paste by mixing bicarbonate of soda with water. Apply the paste to the limescale deposits on the granite. Allow the paste to sit for several minutes. Scrub the limescale deposits with a soft-bristled brush.
Granite's Heat Resistance
An extreme heat source over an extended period could damage granite surface. The damage that might occur would involve a slight softening of the granite, which could lead to discoloration or gouges in an extreme scenario.
For regular granite cleaning, the best cleaner is nothing more sophisticated than mild dish soap diluted with water. (You can also make a homemade granite cleaner made with a base of rubbing alcohol.) Wet a sponge with water from the tap and squirt dish soap into its center. Bear in mind that granite scratches easily.
Frequent use of vinegar, Windex or bleach will dull the granite and weaken the sealant. Instead, a little soap and water should do the trick. Add dish soap and warm water to a sponge, get a good lather and begin cleaning. Avoid using abrasive pads, as granite can be scratched.
Start by cleaning the severely burned surface using the cloth and warm water. Lightly sand the burn stain with the sandpaper. While sanding, apply gentle instead of excessive pressure, as heavy pressure can remove multiple layers from the laminate surface. While sanding, attempt to remove the outline of the burn.
Buy a polishing powder designed for natural stone countertops. You'll generally have to mix the powder with water to form a paste. Then “polish” problem areas with a soft cloth. Some products require you to leave the paste on overnight (mostly for stain removal).
Often you can repair a separated crack in the granite countertop by filling in the gaps with an epoxy glue that matches the color of the stone. Some granite professionals even use some of the granite dust from where the break occurs to color the epoxy glue.
In a bowl, combine one part toothpaste with two parts baking soda to create a thick paste. Apply some of the mixture to the white heat mark on your wood table and allow it to sit for a minute or two before wiping it from the surface. You may need to do this a few times in order for the stain to fully disappear.
To clean an oil-based stain, make a baking soda paste with water. If you're dealing with a water-based stain, mix the baking soda with hydrogen peroxide. Apply the paste generously over the stained area: Gently scrub the counter with a soft cloth and rinse thoroughly. Repeat as needed.
Some DIY resources claim vinegar will work as a household cleaner for natural stone, but this information is incorrect — vinegar is acidic and can harm your granite's sealant. An expertly sealed granite countertop should last your home for years with proper care.
Do use a mild detergent soap. Regular Dawn or other dish soaps work well. Do use a soft cloth. No special tools needed here: a soft cloth will help remove all grime and dirt without damaging countertops.
A half teaspoon of dishwashing liquid to 2 cups of water, applied via spray bottle, is typically all it takes to care for granite slabs. Be especially careful of acidic, caustic cleaners to prevent the dulling of granite surfaces.
The list of best disinfectant for granite countertops is short and alcohol-based. Isopropyl, more commonly known as rubbing alcohol, is considered to be the most widely available and effective disinfectant for granite. Rubbing alcohol is a natural bactericide and can also kill fungus and viruses.
Not only is granite heat resistant, it actually absorbs heat quite well. Because of this, hot dishes or pans left on a granite countertop will cool faster than normal. Therefore, it's best to use a towel or hot pad between the pan and the counter.
Granite is a stone that's strong enough to support the weight of small appliances and cutting boards. However, it's prone to damage from sharp objects like knives. Avoid using your granite surface as a cutting board. This can cause chips, scratches, dings, and other damage.
The melting temperature of dry granite at ambient pressure is 1215–1260 °C (2219–2300 °F); it is strongly reduced in the presence of water, down to 650 °C at a few hundred megapascals of pressure.
Do Not Use On Granite or Marble. If you have soft surface countertops like granite or marble, step away from the magic eraser. You can use them on laminate, Corian, quartz, and other solid surface countertops, but do a spot check.
Bar Keepers Friend Granite & Stone Cleaner & Polish is specially formulated for use on smooth, polished stone – including granite, marble, and quartz. Its pH-balanced formula won't scratch or mar stone finishes, and it's gentle enough to use every day.
Though commonly used as a wound disinfectant, hydrogen peroxide also works wonders on your granite tops. A solution of hydrogen peroxide removes stains without bleaching or discoloring your countertops.
