Careful when you wash the walls because the paint will come of with it! 

I don't want to deal with break-downs or complains that they don't do a good job washing or drying.

It went from things like wanting me to let them have a washing machine in the unit even though the owner said no to them and after I explained it's because the pipes can't handle it and sorry, I'm not losing my job over it for you (in a very nice way) -- furious reaction, no more friendship.... to wanting me to tell their neighbor to stop having such loud sex (not kidding) and when I said I don't tell other tenants how to have sex (again in a very nice way, while giggling no doubt), I lost that friendship. 

Reasonable cleaning costs would include the cost of such things as eliminating flea infestations left by the tenant's animals, cleaning the oven, removing decals from walls, removing mildew in bathrooms, defrosting the refrigerator, or washing the kitchen floor.

Our landlord, on the other hand, never hears from us, we pay rent on time, and we keep her place clean and maintained nicely -- it actually looks way better now than it did when we moved in, because we've repaired crumbly wall sections, spackled holes/dents, touched up scratched doors and floorboards, de-stained the linoleum, replaced cracked lightswitch plates, power-washed the patio, washed the blinds (the landlord didn't, there was cat hair embedded in them from a previous tenant, which by the way the landlord wasn't aware of anyone having a cat, LOL), etc.  

My friend said she'd like to wash the mold off the ceiling first, and he told her it wasn't necessary, and he painted over it anyway. 

At first they said they only use the dryer and wash at the laundry mat...then they said they have only used it twice. 

But, otherwise, I just provided them what they were paying for and gave good service by being responsive and taking care of problems right away.Although I admit, as a tenant, I wish someone else would wash my windows LOL.

And sometimes the old stuff is way better.Example: He washing machines (as in "high efficiency). 

Was he a good landlord?
