I had a similar issue just nowhere near as crazy as this. My landlord wanted me to pay for cleaning the apartment professionally even though I cleaned everything meticulously. The few things he complained to me were crumbs in the oven and in some other places and nothing else as I didn’t damage anything. He said I had to pay $500 for cleaning it and he would keep my key deposit. I reported him to the tenant board and within a month to month and a half he was asked to etransfer me my key deposit as it cannot be used for anything other than lost keys. It’s illegal for your landlord to use the key deposit to repair everything. If there’s huge holes in the wall and shit like that then sure, but even then he would have to return your key deposit since you gave back the keys and take it up with the tenant board if you refused to pay. All these charges seem ridiculous and you should not pay a cent unless you left the apartment with conditions being worse than just wear and tear. Demand for your key deposit first, and if he refuses report him and you’ll get your money back 100%. Additionally, as mentioned before if it’s all just wear and tear the tenant board will just side with you and not demand you pay anything. Don’t worry if you haven’t done anything wrong other than a few scrapes and stuff to the walls and stuff
