I am not a health care worker, nor do I play one on TV. However I have worked in health care IT for 10 years. The word of caution I would inject, is in regards to the option of using a bare hand to clean the affected area. I would say this is a last resort substitute, due to the potential health risks associated with it. Hepatitis A is spread through fecal matter in food. If one is not supremely carefully, ie: wash thoroughly ( more than a minute) and then sanitize, you can spread Hep A to your self and your loved ones very easily. 

Fortunately, Hep A is not fatal, mostly just uncomfortable, with a mild fever that passes and diarrhea for up to 30 days or so.
