Will landlord view this negatively?

I’m not even sure if this is illegal to ask my property management company or landlord about something like this? We have a shared laundry room. It’s gross. We even had a homeless person living in it at one point and urinated in there. I called my landlord and was told something along the lines of “well, if you see it, clean it up.” So I did. However it’s very dusty/dirty in there. There hasn’t been a trash bag in the trash bin for months. I want to ask my landlord to cut me a break in rent in exchange for me cleaning and maintaining the laundry room. Not the machines of course. I would just sweep/mop, take out the trash, dust, wipe down the machines, etc. however, I’m worried this will appear unethical of a tenant?
