August 10, 2020

First you must clean…..Then you may disinfect!

• You can help to reduce the spread of the coronavirus by cleaning and disinfecting high touch surfaces, such as doorknobs, light switches, handles, desks, toilets, sinks, faucets, and tables frequently.

• Please put gloves on before cleaning and disinfecting & Dispose of gloves after cleaning and disinfecting. Thoroughly wash your hands after removing your gloves.

• Cleaning with soap and water removes the dirt and decreases the number of germs on surfaces.

• Once surfaces have been cleaned, you can apply the disinfectant to kill any germs that may be left.

What disinfectants kill coronavirus on surfaces?

• Although many products have not been tested against this virus, they're known to work against other, harder-to-kill viruses.

• Products with active ingredients such as ethanol, hydrogen peroxide or quaternary ammonium are recommended. You should check labels for EPA registration numbers.

• Many disinfectants need to remain on surfaces for some time to be effective, this is known as the “DWELL or CONTACT time.” Which means the time a surface must remain wet to do the job. Each product will vary on contact times so be sure to read the labels.

Does bleach work against coronavirus on surfaces?

• Yes. You can make a disinfecting solution by combining 4 teaspoons (about 20 milliliters) of household bleach and 1 quart (slightly less than 1 liter) of water. Read and follow instructions and precautions.

• For example, wear gloves and make sure there's good airflow in the room. Don't mix bleach with ammonia or any other cleanser,(FYI) combining products could produce toxic fumes.

How can I disinfect phones and other electronics?

• Cellphones, laptops, computers, and screens may be wiped with disinfecting wipes that are 70% alcohol. Wipe the entire phone including along the sides and back where you hold it. Let it air dry. Remember to wash your hands when you're done.
