I'm sure that some days would be worse than others. I used to clean houses at one point. Believe me, I've seen some things that you'll NEVER have to clean if you take the job. The worst that going to happen is if someone smears feces in the bathroom. (Yes, it does happen occasionally.) However, the company should supply you with gloves, masks, etc. Just remember, no matter how bad the mess is, you'll have it spotless by the time you are done and you'll always be able to wear personal protective equipment, and you'll have full access to hand sanitizer. You should be fine and I think there are Altot of worse things you could be doing.
