If you suspect that you or another member from your household is infected with the virus that causes COVID-19, you should regularly disinfect areas and objects that may have body fluids on them. Toothbrushes may have saliva or blood on them and have been shown to transmit viruses. A recent study discovered that the SARS-CoV-2 virus can stay on the surfaces for up to 3 days.
Disinfect Your Toothbrush if You Are Sick
For toothbrush disinfection, you can use 3% hydrogen peroxide or dilute it to 0.5% hydrogen peroxide.
0.5% hydrogen peroxide effectively reduces human coronaviruses infectivity in just 1 minute, a recent study analysis found. 0.5% HP is an active ingredient in the products that are listed on the government list of approved disinfectants against the Sars-COV-2 coronavirus. To get a 0.5% HP solution dilute 3% HP with distilled water.
Mix the 1fl oz of 3% hydrogen peroxide with 5 fl oz of distilled water to get 6 fl oz of 0.5% hydrogen peroxide solution.
Soak your toothbrush bristles in the 0.5% hydrogen peroxide solution for 10 minutes. Never use the same cleaning solution again.
Rinse the toothbrush with tap water before you start brushing your teeth.
