I hate this. :( We had stuff in storage. The stuff that was in our garage was ruined by mold. Most of it had to be tossed. The stuff that was in my parents basement was mildewy but salvageable (I thought). The other part of our basement definitely promotes mildew growth, though it's not as bad as the garage. Anything left down there is likely to get covered in fuzz after a while. I do try to protect stuff in plastic bags and boxes, as much as possible.
But our house is old, poorly insulated, and apparently prone to damp. Our windows "weep", so once cold weather hits I am wiping grime and mildew off the frames almost daily. (We have wanted to use insulating plastic on them, but I am afraid I will just be setting myself up with multiple mold farms, by doing that). I am finding books on the shelves that have mildew on them. This morning I found that one of the baskets in the bathroom is fuzzy with mildew. These are things that had some minor mildew on them, and I'd washed them with vinegar and thought they were OK. I am a little worried that the carpets are full of it. :( We don't have money to be tearing stuff out or remodeling. Dh wants to keep the carpets because they provide at least some insulation from the below-ground/unheated basement and the rest of the house.
What are some low-cost/no-cost ways I can reduce some of this icky stuff? Are there any? I am *hoping* that once we turn the heat on, it will dehumidify things a little. But then we will have the spores being blown all over the house. One thing I am going to do is get the disposable vent filters, to try to catch whatever is in the ventilation system before it gets into our lungs. Is there anything else that can be done, that doesn't involve remodeling or ripping stuff out?
