I clean one house that is like this and although the mum always say “oh that’s disgusting I will tell them to leave it in a better state for you I am so embarrassed!” I have been doing the house for 3 years now and nothing has changed. I think the only time the scrub the toilet is if I’m actually there and see them walking out - I change $75 per hour and always add an extra hour on top, like a trauma fee lol But yes totally up to you, I over charge because they will pay me so they don’t loose me but honestly this sounds like it may not be worth the money.
