Question about antiseptics and soap?

Scenario 1: I am cleaning my earrings in hydrogen perozide. I put a little in a cup and put one set of earrings in. When I take them out, is that cup of hydrogen peroxide now contaminated? Doesn’t it kill the germs? If I put another set or earrings in the cup, will they not be sanitized?

Scenario 2: Someone just washed their dirty, germ infested hands with a bar of soap, maybe they even leave a dirt film on the soap. If I lather the soap, is the soap now clean, and germ free?

I have always considered these 2 things “self-cleaning”, but I could be wrong. Anybody know?
