As we head full swing into the school year, it’s no secret that we’re at risk of germs and viruses that are amplified as students come together in tight spaces. Fortunately, we can all do our part in our homes and together in schools to keep illnesses at bay. The key is recognizing the difference between cleaning, sanitizing and disinfecting and ensuring that each one is executed thoroughly and at the optimal times. 

Cleaning removes things such as germs, dirt, pet dander, crumbs and dust from surfaces, most often with soap and water. Sanitizing reduces the number of germs on objects and surfaces to levels considered safe and kills bacteria. On a deeper level, disinfecting kills viruses and bacteria. While cleaning is woven into our daily routines, sanitizing and disinfecting must happen on demand and as needed, such as when a virus is circulating or raw meats were cut or handled. Below, some tips for mastering the art of cleaning, sanitizing and disinfecting. 

Cleaning

To clean, use soap or detergents with water to scrub, wash and rinse. Cleaning should be performed regularly and consistently and should also come before sanitizing or disinfecting an object or surface. This ensures that when you move on to sanitizing or disinfecting, the product or solution will work effectively when applied. To remove germs from your hands, make sure you wash your hands for at least 20 seconds.

Sanitizing

To sanitize, use EPA-registered sanitizing sprays and weaker bleach solutions that have been diluted with water. Sanitize objects and surfaces that come in contact with mouths and food, including cutting surfaces, countertops, doorknobs and toys. Keep in mind that EPA-registered sanitizing solutions only claim to kill bacteria, but not viruses. Sanitization is acceptable for linens, curtains, towels, clothing and backpacks, upholstery and carpets, to name a few.

Disinfecting

To disinfect, enlist the help of a bleach solution or a disinfecting solution that is registered by the EPA for killing bacteria, fungi and viruses. You will be able to find this information on the product’s label. These often include wipes and solutions made by popular brands like Lysol and Clorox. You can also use isopropyl (rubbing) alcohol, ethanol and hydrogen peroxide. 

Be sure to let the product sit on the surface for long enough to effectively kill bacteria and viruses. For example, Lysol disinfectant spray should sit on the surface for three minutes before being wiped off. Directions for disinfecting time are included on the product’s label. 

It’s helpful to disinfect objects that are touched often, such as doorknobs, light switches, remotes and toys.

To be sure, there’s no sure-fire way to avoid the back-to-school bugs that will make their rounds. However, with these tips in mind, you can do your part for your family and your children’s peers and teachers to eliminate the spread of bacteria and viruses.
