If you are wondering about disinfecting your skin, a word of caution: nothing is better to prevent the spread of germs than simply washing your hands with soap and water for at least 20 seconds.

Should I disinfect surfaces with alcohol?

You can disinfect hard objects and objects in your home using regular rubbing alcohol. Found in stores or online, bottled rubbing alcohol is most often made from isopropyl alcohol, a colorless solution that often has a very strong odor.

Rubbing Alcohol

But you shouldn’t consider cleaning your entire house with rubbing alcohol, as these mixtures can be difficult to use effectively when covering large areas. Why? Mixtures that contain more alcohol, although stronger, can evaporate too quickly from surfaces to actually neutralize germs on that surface. While small items with non-porous surfaces, such as house keys or even the surface of a toilet handle, can often be kept wet long enough by reapplying rubbing alcohol, it would be much more difficult to do on a larger surface, not to mention the whole. House.

Disinfect Non-Porous Surfaces

The best way to disinfect your entire home would be to use an EPA approved disinfectant, but if you can’t find these products, bleach might be your next best bet. According to CDC advice, an easy way to disinfect non-porous surfaces is to combine 1/3 cup of regular bleach (sodium hypochlorite) per gallon of water.

For smaller batches, use 4 teaspoons of regular bleach and 1 liter of water. You will need to leave the surface wet for at least five minutes, allowing it to air dry, before rinsing all surfaces with warm water afterward. Be careful not to splash the bleach solution on your clothes or in your eyes, and use it sparingly on sinks and stainless steel surfaces. It is also important to note that the bleach and water solution should be refreshed each day that you use it.

Can I use alcohol to clean my house?

Let’s get straight to the point: no. The types of liquors you use to create your favorite cocktails are not concentrated enough to disinfect surfaces and effectively kill germs and bacteria. Most commercial forms of vodka, for example, contain alcohol concentrations that hover around 40%. Disinfectants that can kill germs have a much higher alcohol concentration which is made very differently from the types of alcohol humans drink orally.

If you encounter a version of an alcoholic product and plan to use it to disinfect, it must contain at least 70% alcohol before even considering using it.
