Introduction
A clean mattress is essential for a good night’s sleep and overall health. Over time, mattresses accumulate dust, sweat, allergens, and even the occasional spill. Regular cleaning not only keeps your mattress fresh but also extends its lifespan. One of the most effective and budget-friendly methods is to clean the mattress using baking soda. This versatile household staple is a powerful deodorizer and stain remover. In this guide, we’ll walk you through seven easy steps on how to clean a mattress using baking soda, ensuring it stays in top condition.

Step 1: Gather Your Supplies
Before you start, make sure you have all the necessary materials and tools:
- Baking soda: The star of our cleaning method, known for its odor-neutralizing properties.
- Vacuum cleaner: Essential for removing dirt, dust, and baking soda.
- Spray bottle: Useful for applying cleaning solutions.
- Clean cloths: For blotting and wiping.
- Essential oils (optional): To add a pleasant scent.
- White vinegar (optional): For tackling tougher stains.
Having these supplies ready will streamline the cleaning process and ensure you don’t have to stop midway to find something.
Step 2: Strip the Bed
The first step in cleaning your mattress is to remove all bedding and linens. Strip off the sheets, pillowcases, and mattress protector, if you use one. Washing your bedding in hot water helps kill dust mites and other allergens. This also ensures that when you put everything back, your bed will be completely fresh and clean.
Step 3: Vacuum the Mattress
Vacuuming your mattress is crucial for removing loose dirt, dust, and other particles. Use the upholstery attachment on your vacuum cleaner for this task. Pay special attention to seams, crevices, and edges where dirt tends to accumulate. A thorough vacuum not only cleans the surface but also prepares the mattress for the baking soda treatment, ensuring it can penetrate deeply and work effectively.
Areas to Focus On:
- Seams and Edges: These are hotspots for dust and dirt.
- Crevices: Often overlooked, these can harbor allergens.
- Top Surface: Make sure to vacuum the entire surface evenly.
Using the right vacuum attachment, preferably one designed for upholstery, will make this task easier and more effective.
Step 4: Deodorize with Baking Soda
Baking soda is excellent for neutralizing odors and freshening up your mattress. Sprinkle an even layer of baking soda over the entire surface of the mattress. You can use a sifter to distribute it evenly. For an extra touch of freshness, add a few drops of your favorite essential oil to the baking soda before sprinkling it on. Popular choices include lavender, eucalyptus, and tea tree oil, which have natural antibacterial properties.

Allow the baking soda to sit on the mattress for at least 15 minutes, but if possible, leave it for a few hours. The longer it sits, the more odors it will absorb.
Why Baking Soda Works:
- Odor Neutralization: Baking soda’s alkaline nature neutralizes acidic odors.
- Moisture Absorption: It helps absorb moisture, preventing mold and mildew growth.
Step 5: Vacuum Again to Remove Baking Soda
After letting the baking soda sit for a sufficient amount of time, it’s time to vacuum it up. Using your vacuum cleaner’s upholstery attachment, go over the entire mattress to remove the baking soda. Make sure to vacuum thoroughly, ensuring no residue is left behind. This step not only removes the baking soda but also any remaining dirt and dust, leaving your mattress clean and fresh.
Tips for Effective Vacuuming:
- Slow and Steady: Move the vacuum slowly to pick up all the baking soda.
- Multiple Passes: Go over the same area multiple times to ensure thorough cleaning.
- Check the Filter: Make sure your vacuum’s filter is clean to maintain suction power.
Step 6: Air Out the Mattress
After cleaning, it’s important to let your mattress air out. This helps remove any remaining moisture and odors. If possible, place the mattress in direct sunlight for a few hours. Sunlight has natural antibacterial properties and can help kill any remaining germs.
If outdoor airing isn’t an option, open windows and use fans to improve air circulation in the room. This will help the mattress dry faster and ensure it’s completely fresh before you put the bedding back on.
Benefits of Airing Out:
- Odor Removal: Fresh air helps eliminate lingering odors.
- Moisture Evaporation: Ensures the mattress is completely dry, preventing mold.
Additional Tips for Maintaining a Clean Mattress
Keeping your mattress clean doesn’t end with these steps. Here are some additional tips to maintain its freshness and hygiene:
Regular Vacuuming and Deodorizing
- Vacuum Weekly: Regular vacuuming helps remove dust and allergens.
- Monthly Deodorizing: Sprinkle baking soda on the mattress once a month and vacuum it up to keep it fresh.
Using Mattress Protectors
- Waterproof Protectors: These can prevent spills and stains from reaching the mattress.
- Allergen Barriers: Protectors can also reduce allergens and dust mites.
Rotating and Flipping the Mattress
- Every 3-6 Months: Rotate and flip your mattress to ensure even wear and prevent sagging.
- Spot Cleaning: Address spills and stains immediately to prevent them from setting.
Seasonal Deep Cleaning Routine
- Spring and Fall: Perform a thorough cleaning twice a year to keep your mattress in top condition.
