This isn't a caregiving question per se, but I'm having to clean out the apartment of a man that was a hoarder. My 91 year old dad is the landlord (I help him take care of my mother). The poor man was sick and he left an absolutely nasty bathroom. The toilet wasn't working properly but he didn't inform my dad. Used toilet paper on the floor... you can imagine the rest. When my dad didn't receive his rent, he went to check on him because he was always punctual and that's when he found out about the toilet, and the mess. He lived alone and only has one sister that placed him in hospice (which is why we couldn’t find him) but isn’t interested in cleaning up after him so I have to clean up a disaster area. My question is, if anyone has had any experience in your caregiving of cleaning a nasty, crusty inside and out toilet, what did you use? Do I need to get hospital type cleaner? If so, where would I get that? I’ve already bought a respirator. I want to know that it's clean and sanitary for the next renter.
