....handwashing. It reinnoculates the hands.
Also, if one's hands have been contaminated and then one touches their mask before washing again, then the mucous membranes are often touched in this case. Alsothe homemade masks become innoculated, and the virus can go right through them.
The size of the water vapor droplets that can spread the virus are extremely small.
I have used this example before - expecting your homemade mask to prevent the spread of this virus is like expecting a chain link fence to keep mosquitos out of your yard.
The fall back rationalization usedby the mask nazi's that "at least it will block the bigger droplets if you sneeze" is laughable when you consider the cloud that is not stopped on a microscopic level as well as the fact that increased face touching and mask reuse and improper technique of mask placement and removal negates any of these other minor benefits as well.
Here is Dr Fauci on around April 1, 2020 on 60 minutes BEFORE masks became politicized and you got his honest, unrehearsed opinion:
