Outdoor furniture plays a major role in creating a cozy backyard, patio, or balcony setup. However, one of the biggest hindrances for your assets is mold. Mold and mildew not only damage furniture and outdoor furniture covers, but they also bring unpleasant odors and potential health hazards.
Why does mold grow on furniture covers?
Not all outdoor chair covers, waterproof cushion covers, and custom BBQ covers are made to withstand the weather conditions. They might be good in resolving a few weather conditions, but they can lack other features that prevents the mold growth, etc. Here’s why:
- Trapped moisture: Waterproof covers can trap humidity inside if they’re not breathable, creating an environment for mold to grow.
- Poor ventilation: Covers without air vents or breathable fabric don’t allow moisture to escape, leading to mold growth.
- Lack of sunlight: Covers left untouched in shady areas in damp weather tend to develop mildew faster.
Proper measures for these causes may help you prevent mold before it starts.
How to Prevent Mold on Outdoor Furniture Covers
1. Choose Breathable Waterproof Covers

When shopping for outdoor furniture covers, look for materials that are both waterproof and breathable. This duo keeps raining out but allows moisture and condensation to escape. It’s especially important for outdoor cushion covers and custom covers that are meant to be wrapped tightly around furniture.
Tip: Go for Custom Covers with built-in vents or breathable panels. Fabrics like polyester with PVC or PU coating often provide the right balance of water resistance and breathability.
2. Keep Furniture and Covers Dry
Always make sure your furniture is dry before covering it. Wiping down cushions and frames after rain or morning dew can go a long way.
If you’re using storage bags for outdoor covers, ensure the covers are bone-dry before storing them. Damp covers kept in sealed bags are like an invitation to mold growth.
3. Elevate and Ventilate
Wherever possible, elevate furniture slightly off the ground or place covers so that air can circulate underneath. Avoid letting covers sit flat against the patio floor where water pools and humidity linger.
4. Regular Cleaning and Inspection
Even the best custom BBQ covers, or waterproof cushion covers, need occasional cleaning. Remove dust, dirt, and organic matter regularly to keep mold spores at bay.
Best Way to Clean Mildew Off Patio Furniture Covers
If your covers have already caught some mildew, don’t panic. Here’s how to handle it:-
1. Use a Mild Cleaning Solution
You don’t need harsh chemicals. Mix one of the following:
- 1-part white vinegar + 1 part water
- 1 tablespoon dish soap + 1-quart warm water
Apply the mixture using a soft-bristle brush or sponge.
2. Scrub and Rinse
Gently scrub the mildew spots in circular motions. Rinse thoroughly with clean water to remove all residue.
3. Dry Thoroughly
Let the covers dry completely in sunlight if possible. Sunlight naturally kills mold, and mildew spores and prevents regrowth.
Cleaning Solutions for Moldy Patio Furniture Covers
Here are a few mold-fighting options that are safe for most outdoor fabrics:-
- Vinegar: A natural and effective mold killer.
- Hydrogen Peroxide: Use 3% solution; test on a small area first to avoid discoloration.
- Baking Soda Paste: For mild stains, this gentle scrub helps remove spores and neutralize odors.
Avoid bleach unless the cover manufacturer explicitly states it’s safe. It can damage waterproof coatings and fabric colors.
Tips to Stop Mold Growth on Outdoor Cushion Covers
- Bring cushions indoors during heavy rain or snow.
- Use cushion storage bags that are breathable and moisture resistant.
- Avoid stacking wet cushions. Air them out after use.
- Spray with fabric protectant every few months to repel water and mold spores.
How to Remove Mold from Outdoor Fabric Covers
If mold is deeply embedded in your covers, follow these steps:
- Brush off loose mold outdoors to prevent spores spreading inside.
- Soak the fabric in a vinegar-water bath or use a mold-specific cleaner.
- Rinse and let it dry in direct sunlight for a natural sterilization effect.
- Repeat if needed and treat with a mold-resistant spray afterward.
How to Keep Outdoor Furniture Covers Dry and Mold-Free
Consistency is the key. Here’s your checklist:
- ✔ Choose custom covers with proper fit and ventilation
- ✔ Wipe furniture before covering
- ✔ Clean covers monthly or as needed
- ✔ Never store damp covers
- ✔ Use storage bags for outdoor covers that breathe
- ✔ Allow occasional sun exposure to both furniture and covers
Why Custom Covers are the Best Investment
Custom covers aren’t just about aesthetics they protect better. A snug, well-fitted cover leaves fewer gaps for moisture and mold to sneak in. Whether it’s a custom BBQ cover, sectional sofa, or lounge chair, tailored protection gives you peace of mind all year.
Plus, they often come with options like venting systems, padded handles, and waterproof coatings that are optimized for outdoor use.
Conclusion
Mold and mildew on outdoor furniture covers are common but completely preventable. The right materials, regular cleaning, and smart storage make all the difference. Invest in breathable waterproof covers, custom covers, and storage bags for outdoor covers to extend the life of your patio setup and keep it fresh, clean, and inviting.
