What is a cleaner that is even stronger than bleach? Maybe hospital grade?

I want it to clean my apartment I just moved into. I want to get rid of any traces of the previous tenants. I live cleaning with bleach, but I would like something more powerful that disinfects better than bleach that I can buy. Especially for the bathroom. If I can buy hospital grade cleaner that would be great... show more I want it to clean my apartment I just moved into. I want to get rid of any traces of the previous tenants.

If I can buy hospital grade cleaner that would be great too. Any suggestions?
