How long does the virus that causes COVID-19 survive on surfaces, and how should those surfaces be cleaned and disinfected ?
The COVID-19 virus, SARS-CoV-2, can survive on surfaces for varying lengths of time, depending on factors such as the type of surface, temperature, humidity, and the amount of virus present. The timeline for virus survival on surfaces includes up to 4 hours on copper, up to 24 hours on cardboard, and up to 72 hours on plastic, stainless steel, glass, banknotes, and coins. To effectively clean and disinfect surfaces, it is recommended to follow a two-step process: cleaning the surface with soap or detergent and water, and then disinfecting the surface with an EPA-approved disinfectant. Examples of approved disinfectants include diluted bleach, alcohol solutions with at least 70% alcohol, hydrogen peroxide (3%), and quaternary ammonium compounds. It is important to wear gloves when handling disinfectants, ensure proper ventilation, never mix different cleaning products, and disinfect frequently touched surfaces regularly.

Can regular cleaning and disinfection prevent the transmission of other viruses besides COVID-19 ?
Regular cleaning and disinfection can prevent the transmission of other viruses besides COVID-19, such as those causing colds and flu. The CDC recommends routine cleaning of frequently touched surfaces to reduce the risk of infection. Effective cleaning involves using soap or detergent to remove dirt, followed by disinfecting with a product labeled for the specific virus. High-touch surfaces should be prioritized, and proper ventilation and glove use are advised. Following these practices helps create a safer environment.
How do I make a non-toxic all-purpose cleaner using vinegar and baking soda ?
Vinegar and baking soda can be combined to create a non-toxic all-purpose cleaner. Ingredients include white vinegar, water, baking soda, a measuring cup, and a spray bottle. Mix one cup of vinegar with one cup of water and add one tablespoon of baking soda. Shake well before using on most surfaces. Test on a small area first and avoid use on certain surfaces such as marble or unfinished wood. This homemade cleaner is effective, environmentally friendly, and cost-efficient.
Is there a natural alternative to bleach that can be used for disinfecting surfaces ?
There are several natural alternatives to bleach that can be used for disinfecting surfaces, including vinegar, hydrogen peroxide, and tea tree oil. These alternatives are effective against bacteria, viruses, and fungi, and are also safer and eco-friendly compared to bleach. Vinegar is inexpensive and easy to find, but has a strong smell and may damage certain surfaces if left on for too long. Hydrogen peroxide is also inexpensive and easy to find, but can be harmful if ingested or inhaled in large quantities and may fade certain fabrics or surfaces if left on for too long. Tea tree oil is a natural antimicrobial agent that is safe for pets and children, but is expensive compared to other natural disinfectants and may cause skin irritation if not diluted properly. By using these natural disinfectants, you can keep your home clean and healthy without exposing yourself or your family to harsh chemicals.
