You and Stephanie are in my thoughts and prayers. May God bring her healing and you comfort and peace as you so faithfully watch out for her. Good instinct on the handwashing, stick to your guns. It is not an outrageous thing to ask. Hugs to you!
Concerned, I know you have a lot on your mind. Fwiw, here’s what the Mayo Clinic has on handwashing w/hand sanitizer; I hope this helps:

Proper use of an alcohol-based hand sanitizer
Alcohol-based hand sanitizers — which don’t require water — are an excellent alternative to hand washing, particularly when soap and water aren’t available. They’re actually more effective than soap and water in killing bacteria and viruses that cause disease. Commercially prepared hand sanitizers contain ingredients that help prevent skin dryness. Using these products can result in less skin dryness and irritation than hand washing.
Not all hand sanitizers are created equal, though. Some “waterless” hand sanitizers don’t contain alcohol. Use only the alcohol-based products. The CDC recommends choosing products that contain at least 60 percent alcohol.
To use an alcohol-based hand sanitizer:
Apply about 1/2 teaspoon of the product to the palm of your hand.
Rub your hands together, covering all surfaces of your hands, until they’re dry.
If your hands are visibly dirty, however, wash with soap and water, if available, rather than a sanitizer.
