Dear Home Ec 101,
I’ve been wanting to write you for a while! I have smelly sheets! I wash them and I promise I don’t use too much laundry detergent. Then I dry them and then store them in a built-in bookshelf that’s in our closet. For some reason as soon as I get the sheets out to put on the bed they smell weird, a little musty. However they are completely dry when I put them up. I hang up our wet laundry to dry in our closet, do you think that could be the reason?
Also, I have noticed on a set of our nice silver sheets that reddish stains have formed. Not blood or anything like that, but a little like the red mold/mildew you get in the shower. I wash them with color safe bleach and it still doesn’t come out! Any advice?
Thank you so much for all your help! Keep up the great work!

First of all, thank you for submitting your question.
How do you solve the mildew problem?
Bacteria and fungi are usually the source of musty odors and their favorite conditions are damp and still. Unless your closet is well ventilated, it may not be a great place to store your bedding. Cotton is hygroscopic, this is a fancy word that means it can absorb water from the air. So even though your sheets are perfectly dry when they are placed on the shelf, they absorb the humidity in the air providing a great environment for bacteria and mildew. The organisms’ waste is the source of the musty smell. Now there’s an appetizing thought for you.
It may be time to find a new place to dry your laundry. To reduce the amount of mildew, mold, and bacteria in the closet, you must reduce the humidity. To further reduce the amount of mildew spores, I’d give the shelves a good wipe down with a dilute bleach solution, dilute white vinegar, or tea tree oil. Run a fan in the room until the shelf is completely dry before storing clean sheets.
It may also be worthwhile to use a desiccant like DampRid in the closet.
Another way to tackle the musty odor may be to ask yourself:
How much bedding are you storing?
Do you have more sheets than necessary?
For each bed we have two sets of sheets. One goes on the bed and the other set is stored flat, between the mattress and the box spring. Every Monday the beds are stripped, the dirty sheets are washed, and the spare set is put on the mattress. When the sheets are clean and fully dry, they are tucked.
The discoloration is likely oxidation -that’s a reaction similar to what happens when iron rusts- caused by salts in you or your partner’s sweat or a reaction with benzyl peroxide, which is in many topical acne treatments. Both of these are permanent chemical reactions that have changed the color of your sheets. Don’t kill yourself trying to remove the stain, it’s usually irreversible. If the culprit is acne medication, try to put it on earlier in the evening so it can dry completely before going to bed. Additionally, you may want to use an old pillowcase rather than one intended for decoration.
