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.
Hot water and dish soap should be adequate for daily sanitizing. However, if a disinfectant is desired, reach for a bottle of 70% isopropyl alcohol. Spray it onto the granite, allow to sit for three to five minutes, and then rinse with water and dry with a clean microfiber cloth.
Hot water and dish soap should be adequate for daily sanitizing. However, if a stronger disinfectant is desired, mix together a 50:50 solution of water and 91% isopropyl alcohol. Spray onto the granite, allow to sit for 3-5 minutes, then rinse with water and dry with a clean microfiber cloth.
A solution of 50% water and 50% isopropyl alcohol (91% or less) can be used occasionally to restore the granite's shine. While some commercial cleaners are okay, they may break down the seal faster. It's best to use only dish soap and water.
Fancy cleaners aren't necessary for cleaning granite counters on a daily basis. You really only need three things: Warm water, mild dishwashing liquid and a microfiber cloth. Tip: Make sure your dishwashing liquid doesn't contain citrus extracts, as they're too acidic for granite countertops.
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).
Mix one part water and one part rubbing alcohol in a spray bottle. Spray it on the countertop and let the disinfectant sit for five minutes. Rinse with a damp cloth and buff the granite with a dry microfiber cloth to restore the shine.
If after a few minutes the water has soaked into the granite, then it's time to reseal the stone. 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.
How To Sanitize Countertops: Spray your counters with isopropyl rubbing alcohol (at least 70%). Wipe them down with a clean microfiber cloth. Dry your counters with a dry microfiber cloth.
Generally, over time the haze goes away after you wipe down your counters as you clean periodically. But if you want to act now, try using a damp towel followed by a dry towel to remove the haze. If that doesn't work, a mixture of dish soap and water applied with a microfiber cloth should clean it up.
Isopropyl alcohol is pure alcohol and is a colorless liquid with a musty, sharp odor. There are no other ingredients in a bottle of isopropyl alcohol. By contrast, rubbing alcohol contains isopropyl alcohol among other ingredients, such as water. Most rubbing alcohol brands contain 70% isopropyl alcohol.
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.
Mix baking soda, hydrogen peroxide, and warm water in a bowl until there is a thick paste. 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.
Even though you may think the higher concentration is more effective, experts say 70% is actually better for disinfecting. It has more water, which helps it to dissolve more slowly, penetrate cells, and kill bacteria. The disinfecting power of rubbing alcohol drops at concentrations higher than 80%-85%.
70% isopropyl alcohol is by far better at killing bacteria and viruses than 99% isopropyl alcohol. As a disinfectant, 70% concentration of alcohol is the most effective at killing pathogens. Any higher or lower percentage will be less effective.
Finished surfaces: Since the ethanol in it is a solvent, rubbing alcohol can liquify varnishes or finishes, doing major damage to your furniture or other surfaces in your home. Avoid rubbing alcohol on painted, shellacked, lacquered, or varnished surfaces, including treated wood.
A mild dish soap is the handiest cleaner you have that is safe for granite. Alternatively, consider a commercial cleaner that's specifically formulated for granite. Many natural cleaning products are also safe for use on this surface, but read the label for confirmation before using them.
Isopropyl alcohol is a potent antimicrobial, killing microorganisms by inhibiting their growth and stopping their spread. It kills 99.99% of germs within 10-30 seconds of its application, making it one of the best sterilization tools. IPA kills bacteria by damaging the cell wall of an organism.
It leaves no residue and evaporates quickly relative to water. It is low toxicity compared to alternative solvents and is similarly relatively environmentally benign, being ozone safe with excellent “green solvent” scores.
Flush the area with a mix of water and mild dish soap; rinse several times. Dry the area thoroughly with a soft cloth. Repeat as necessary. Avoid harsh cleaners: Granites may contain trace levels of acid-sensitive minerals, so don't use cleaning products containing lemon, vinegar, or other acids.
The best alternative, when you need to disinfect natural stone countertops, is rubbing alcohol with 70% or higher alcohol content. Alcohol is relatively neutral in pH, so it won't etch marble or softer granites.
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.
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.
As good as a cleaner for windows and other glass surfaces, Windex has some elements on its compositions that can permanently damage granite when used for a long time. For that reason, you should never use Windex on granite.
Clorox and Lysol sprays and wipes are convenient, but they are not safe for granite countertops. They rarely contain bleach, but they do generally contain citric acid to help remove soap scum. Avoid using bleach as well.
