This used to be my family. Our washer was soooo old, I think some of the mildew smell came from the machine. We also had moisture in our basement. I ran a large de-humidifier 24/7 and it would pull 6-8 gallons of water each day.
We had to re-grade our yard, pour new concrete, buy a new washer, and get new gutters to actually fix the problem. Ugh it took a lot.
Anyways, I’m still self-conscious our home might have that smell. I’ve asked my mom to tell me, truthfully, if the odor was still there and she says no. But I’m still worried.. I more of a shy/quiet type with some people but I would want to know. I plan to ask my licensor tomorrow when she’s out lol I just want to be SURE it’s gone.
I think saying something kindly, not make it a big deal but just a heads up, would be a good idea
it’s like letting someone walk around with TP on their shoe
If she needs non-expensive ideas.. stronger smelling detergent and fabric sheets, plus de-humidifier, helped us in the interim.
