How to Clean a Mattress That's Been in Storage?

Mattresses that have been in storage can accumulate dust, absorb moisture, and develop odors. Cleaning them properly before use is essential to ensure they provide the comfort and cleanliness you expect, much like the experience of sleeping on a new Puffy mattress.

How to Clean a Mattress That Has Been in Storage

Reviving a mattress from storage is crucial for ensuring it’s clean, comfortable, and safe to sleep on. Here’s an effective approach to cleaning a mattress that has been in storage:

Cleaning Steps:

  1. Inspect the Mattress: Before proceeding with any cleaning, thoroughly inspect the mattress for signs of mold, mildew, or significant wear. If extensive mold is found, it might be more prudent to replace the mattress.

  2. Air It Out: Position the mattress in a well-ventilated area or, if possible, outside in the sun for several hours. Sunlight has natural sanitizing properties and can help eliminate any lingering storage smells. Ensure the mattress is completely dry before bringing it back inside.

  3. Vacuum the Mattress: Using the upholstery attachment of your vacuum cleaner, thoroughly vacuum the entire mattress. Focus on all surfaces, including the sides and any seams or tufts, as these areas can harbor dust and allergens.

Deep Cleaning Process:

  • Spot Cleaning: Mix a mild detergent with water or use an appropriate fabric cleaner for any visible stains. Gently apply the solution with a soft cloth, being careful not to oversaturate the mattress.

  • Deodorizing: For a thorough deodorization, liberally sprinkle baking soda over the entire mattress surface. The baking soda will absorb odors and any residual moisture. Leave it on for several hours — ideally up to 24 hours — before vacuuming it off thoroughly.

  • Disinfecting: In cases where deep disinfection is needed, use a fabric-safe disinfectant spray. Spray lightly over the mattress surface and allow it to air dry completely.

Maintaining a Clean Mattress Post-Storage

After cleaning, ongoing maintenance is key to keeping your mattress in top condition.

Maintenance Tips:

  • Use a Mattress Protector: A good quality protector will shield against dust, spills, and allergens.
  • Regular Vacuuming: Vacuum your mattress every few months to keep dust and allergens at bay.
  • Air Out Regularly: Let your mattress breathe by airing it out occasionally, especially if it’s been in an enclosed space.

Puffy mattresses are designed to resist allergens and are easy to maintain, but even they benefit from regular cleaning and airing, especially after being in storage.

Addressing Mold and Mildew

If your mattress has developed mold or mildew during storage, it requires special attention.

Mold Removal Steps:

  • Safety First: Wear gloves and a mask to protect yourself from mold spores.
  • Mold Cleaning Solution: Use a mixture of white vinegar and water to clean the affected area. You can also use a commercial mold remover designed for fabrics.
  • Dry Thoroughly: Ensure the mattress is completely dry before using it. A damp mattress can lead to more mold growth.

Dealing With Persistent Odors

Sometimes, a mattress can retain a musty smell after being in storage.

Odor Elimination Techniques:

  • Baking Soda Treatment: A more extended baking soda treatment can help eliminate stubborn odors. Leave the baking soda on the mattress for up to 24 hours before vacuuming.
  • Air Purification: Placing the mattress in a room with an air purifier can also help remove lingering odors.

Storing a Mattress Properly to Avoid Future Issues

Proper storage techniques can prevent many of the issues associated with storing mattresses.

Effective Storage Methods:

  • Clean Before Storing: Vacuum and deodorize the mattress before storage.
  • Use a Mattress Bag: A breathable mattress bag will protect against dust and moisture.
  • Avoid Damp Locations: Store the mattress in a dry, climate-controlled environment.
