Big problem; likely due to the recent humid weather, both the mattresses in my rented apartment have developed a strong musty/moldy smell. Sheets placed on them quickly take on the same odor, pillows get similarly 'infected'. Pretty bad. At this point they certainly aren't safe to sleep on, and I've removed both mattresses to a spare room.
I've tried airing them out with fans, getting them in the sun, but with no success. I obviously need to talk to my landlord about this, but I'm not sure what approach to take. My apartment isn't exactly high-end, and I highly doubt he'll be willing to buy new mattresses. I also suspect I will meet resistance requesting they be removed and disposed of, which is what needs to be done at this point. I've only got three months left on the agreement for this place, but would rather avoid the hassle of moving out early. Place was sold as furnished, so in a sense I feel entitled to a clean mattress.
Any suggestions on how I should approach the landlord?
