You can mix a 50/50 solution of water and rubbing alcohol to disinfect your hard-surface countertops, like granite and quartz. Hospitals also sometimes use alcohol towelettes to get rid of germs on small surfaces like stethoscopes, scissors, and thermometers.
Isopropyl alcohol does need to be mixed with water until a concentration of 70% isopropyl alcohol and (at least) 30% water. Higher percentage of water up to a 50/50 or 1:1 ratio mixture (50% isopropyl alcohol and 50% water) is a better disinfectant than 90% isopropyl alcohol.
70% Isopropyl Alcohol: With 30% water content, this concentration is optimal for disinfecting purposes. The presence of water slows evaporation and enhances the alcohol's ability to penetrate microbial cell walls, leading to more effective sterilization.
Mixing Ratio: To dilute, you can mix a specific volume of isopropyl alcohol with water. For instance, to dilute 100 ml of 99% isopropyl alcohol to about 70%, you would add approximately 30 ml of water. Storage: Once diluted, store the solution in a clean, labeled container to avoid confusion and contamination.
If you mix equal parts of water and rubbing alcohol, the solution will be a 50/50 mixture, which is commonly used as a disinfectant. Solutions with a higher concentration of alcohol will have a stronger effect as a disinfectant, but they will also evaporate faster.
What to expect. Alcohol makes swirly patterns as it goes into the water. When stirred, the alcohol completely dissolves into the water.
Here you go: 1/4 cup rubbing alcohol, 3 drops Castile soap, 16 ounces of water. Just put in a spray bottle and enjoy!
TO MAKE A STANDARD SOLUTION (70%):
Dilute by adding 1 part water to 2 parts of this 99% Isopropyl Alcohol.
Rubbing alcohol with concentrations of 70-91% kills bed bugs quickly upon contact if applied correctly and directly to the pests. At this concentration, rubbing alcohol dissolves and desiccates the bed bug's protective exoskeleton.
No – isopropyl alcohol and rubbing alcohol are not the same thing. 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.
Here's how to do it: Combine 1 1/2 cups rubbing alcohol with 3/4 cups water and 15 drops each of lavender and lemon essential oil in a metal or glass spray bottle. You can use this spray to disinfect everything you would typically use Lysol for, including toilets, laptops, bathrooms surfaces, door handles, and more.
Follow the directions on the bleach bottle for preparing a diluted bleach solution. If your bottle does not have directions, you can make a bleach solution by mixing: 5 tablespoons (1/3 cup) of bleach per gallon of room temperature water or. 4 teaspoons of bleach per quart of room temperature water.
Isopropyl alcohol, particularly in solutions between 60% and 90% alcohol with 10 – 40% purified water, is rapidly antimicrobial against bacteria, fungi, and viruses.
A good way to use it is to mix about 2 tablespoons with a half-gallon of water and put it in a spray bottle or bucket.
Rubbing alcohol does kill bed bugs. It works by dissolving their exoskeleton and dehydrating their insides. However, it's not the most effective method to eliminate a bed bug infestation since it only kills the bugs on direct contact and won't reach the bugs hiding in a mattress or upholstered furniture.
Vinegar is a powerful insecticide that can disrupt the nervous system of bed bugs and kill them. The benefit of the method is that vinegar won't evaporate as quickly as rubbing alcohol.
- How to properly dilute and use IPA. Solutions of 70% IPA in water should be left on surfaces for 30 seconds to ensure disinfection. Pure (100%) IPA evaporates too quickly for such use and is less effective. - To clean surfaces with soap and water before cleaning with IPA.

EFFECTS ON HUMANS
The lethal dose of isopropyl alcohol is estimated as 160-240 ml (Ashkar and Miller, 1971) and 250 ml (McBay, 1973). In 1978, 372 Melanesian men consumed a solution of 82% methyl alcohol and 18% isopropyl alcohol in the mistaken belief that the solution was methylated spirits; 18 of them died.
Add 4 tablespoons (1/4 cup) Dawn Platinum Dishwashing Liquid. Add 1 1/2 tablespoons 70% isopropyl alcohol. Apply spray top. Shake gently to combine ingredients.
Stronger Isn't Always Better
You can buy rubbing alcohol with a concentration of 70% or 99% isopropyl alcohol. Even though you may think the higher concentration is more effective, experts say 70% is actually better for disinfecting.
