General cleaning before moving out

The mother of the owner of this house we are renting now told me to maintain the house properly. Of course! She even mentioned that the former occupants are keeping the house tidy always. Really? When we moved here, the walls have dirt marks, the window grills’ white paint almost turned to gray because of dust, the floor and walls of the comfort room needs thorough brushing, the cabinet under the sink is full of empty ice cream containers, egg trays, broken faucets, and a lot more stuffs that the former renters must have thrown before they left. Seems like it wasn’t cleaned for so long because it has become a home for the cockroaches. The former renters left a month before we moved in. So that’s how they maintain the house? I am not into cleaning so much because I am not an OC in that aspect. But I do general cleaning before moving so it won’t be hard for the next occupants to clean. This house that we moved in? Seems it was not cleaned for 48 years.LOL.
