For those without that garage, you can clean and/or sanitize your groceries before you even put it in your car! Sanitize each item and place it in a clean pre-sanitized container in your car. We use folding cargo bins that fold flat, and this will be our clean area to move our groceries from the bags within the shopping cart into the car, and later into our home. Throw away all external containers, bags, etc at a trash receptacle at the store. Don't forget to maintain a safe distance between you and others of six feet!
If you do have a garage, I say to not consider any bag or container as being absolutely clean! Be careful to place the grocery bags etc on your dirty areas before cleaning, as in the case as seen in the video, in such a manner in which the bags are not agitated as to shake off any seen/unseen particles.
I thank Doctor Jeffrey VanWingen for thinking ahead and making this video! Thanks to all who work hard to keep us safe and healthy during these crazy times!!
