Short answer
Mold grows when clothes stay damp. The simplest plan is to store only clean, fully dry clothes, use breathable storage, and keep humidity low.
If you are moving or need extra space, you can compare storage options near you with get-matched to find places that fit your timeline.
Details
Step 1. Clean and dry completely. Wash or dry clean clothes first. Then make sure they are dry all the way through before packing. If an item feels cool or slightly damp, keep drying it.
Step 2. Use the right containers. For everyday clothes, use bins with vents or breathable fabric bags. Avoid sealing damp clothes in airtight bags, especially right after washing. If you want extra protection, use a storage bag that still allows some airflow.
Step 3. Add moisture control. Put moisture-absorbing packets or a dehumidifier in the storage area if the space allows it. Do not let packets touch fabric directly. Place them in the bin corner or a separate container.
Step 4. Keep air moving. Do not stack bins so high that air cannot circulate. Leave a little space between items when possible. If you can choose a unit, an interior climate-controlled space usually helps, especially in humid months.
Step 5. Check and rotate. Inspect stored clothes every 4 to 6 weeks at first, then a bit less often. Look for musty smell, spots, or a fuzzy surface. Rewash and fully dry any affected items before returning them.
Cost note
Storage prices vary by city, size, and whether the space is climate controlled. As a general guide, smaller units cost less than larger ones, and climate-controlled setups often cost more than non-climate units. For a quick estimate, start at answers and then compare options using get-matched.

Next step
Before you move clothes into storage, make a one-day plan: wash, dry fully, pack with breathable material, and add moisture control. Then pick a storage option that matches your needs.
Use get-matched to compare storage near you and find a space that supports dry, clean storage.
Common questions
Can I store clothes right after they are washed?
No. Wait until clothes are fully dry. If they still feel damp or smell “wet,” keep drying before storing.
Are airtight bags bad for stored clothes?
They can be risky if clothes are not completely dry. If you use airtight bags, only pack clothes that are bone-dry and clean.
How often should I check stored clothes for mold?
Check every 4 to 6 weeks for the first couple of months. If all looks good, you can check less often.
What should I do if I find mildew?
Do not put the clothes back in storage. Wash the items, fully dry them, and treat the storage bin or bag with soap and water, then dry it completely.
