Rubbing alcohol is a natural bactericide and can also kill fungus and viruses. It has no ill effects on your granite or the seal on your granite so it's an ideal way to keep countertops clean. The list of disinfectants that are harmful for granite countertops is very long.
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 water and isopropyl alcohol solution is an excellent choice for shining and disinfecting even the dirtiest surfaces. An effective solution contains equal parts water and isopropyl alcohol. Simply mix the ingredients together and spray them onto the granite surface.
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.
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.
In fact, the most effective concentration for killing bacteria is 60% to 90%. So 70% isopropyl alcohol is the best disinfectant for granite countertops.
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.
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.
Here's how to disinfect granite countertops safely. 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.
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.
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.
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.
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%.
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.
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.
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.
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.
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.
Granite polishing powder: Also called stone polishing compound, powder offers a quick and easy way to put a fresh gleam on granite while removing minor scratches and stains. If using it dry, choose a buff polishing pad to work the polish over the surface of the granite in a steady, circular pattern.
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.
Pearson recommends rubbing alcohol and water to create a safe cleanser and stain-remover to get rid of any buildup without having to resort to abrasive cleaners. This method will give that extra kick without risking damage to the quartz surfaces.
Typically, granite should be resealed every 12 to 18 months. Nevertheless, there are some other factors that come into play when determining how often to reseal granite countertops. For example, a lighter colored granite will need to be resealed more often because it is typically more porous.
