Everyone loves the rainy season. That gentle drop falling on the leaves and turning the entire landscape into a dreamy, lush green vision is something we all look forward to. But who would have thought those beautiful raindrops could turn your outdoor furniture and covers into one of nature’s biggest nuisances?
Imagine sipping a cup of coffee on your patio, only to be greeted by awful mould and mildew. Mould isn’t just unsightly it can break down fabric, damage furniture, and pose serious health risks over time.
Fret not! This guide will walk you through all the important factors and solutions you’ve been looking for. Let’s get started with why outdoor furniture covers get mouldy, how to remove mold effectively, and, most importantly how to prevent mould on outdoor furniture covers.
Why Do Outdoor Furniture Covers Get Mouldy?
Even the sturdiest outdoor furniture covers face challenges in damp, humid conditions. When moisture gets trapped under a cover especially one that isn’t breathable or properly ventilated it creates the ideal environment for molud and mildew to grow.
Combine that with limited airflow, shady areas, or infrequent cleaning, and you’ve got the perfect storm for fungi.
Best Way to Clean Mildew Off Patio Furniture Covers
If you are dealing with mildew and finding the best way to clean mildew off patio furniture covers without damaging the fabric. Here is your easy cleaning guide:
Step-by-Step Cleaning Guide:
- Brush Off Loose Spores: Use a soft brush to remove dry mildew before washing.
- Use a Mould-Fighting Solution: Mix warm water with white vinegar or a mild detergent. For stubborn spots, you can add a small amount of baking soda.
- Scrub Gently: Using a sponge or cloth, scrub affected areas in circular motions.
- Rinse Thoroughly: Avoid leaving any residue that could attract more mould.
- Air Dry Completely: Hang the cover in direct sunlight to dry fully. Never store damp covers.
There are many cleaning solutions for mouldy patio furniture covers, but natural mixes like vinegar and baking soda often work just as well as store-bought alternatives.
How to Remove Mould from Outdoor Fabric Covers
For deeper infestations, you may need a more concentrated approach:
- Mix one part vinegar with one part water.
- Spray it on the cover and let it sit for 15–30 minutes.
- Rinse well and allow it to dry in a well-ventilated area.
This method is safe for most custom covers and custom tarps, especially those made of high-quality polyester or treated canvas.
Tips to Stop Mould Growth on Outdoor Furniture Covers
It’s better to find a cure than to lurch cluelessly, right? So, here are some easy tips to stop mould growth on outdoor cushion covers:
- Use breathable covers: Breathability helps reduce trapped moisture. Look for mould-resistant outdoor furniture cover materials such as patio table covers that allow air to circulate while keeping rain out.
- Choose water-resistant or waterproof covers: While breathability matters, your cover should also repel water. Choose your outdoor covers such as bbq covers, outdoor storage covers, and custom covers in materials that strike this balance.
- Clean regularly: Monthly light cleanings can keep mildew from settling in.
- Store properly: Always fold and store the covers in a shaded, dry area when not in use.
Choosing the Right Covers Matters
This is where prevention truly begins. The quality of the cover you use has a major impact on whether mould and mildew will take hold or stay away. Many inexpensive options on the market may look good initially but fall short when tested by rain, humidity, or seasonal weather changes.

Pro Tip: Always choose covers (be it a custom chair cover or table cover) designed with performance in mind.
What to Look for in a Mould-Resistant Outdoor Cover:
- Breathable Fabric: Look for materials that allow air to pass through while preventing water from seeping in. This prevents the moisture buildup that leads to mold.
- Water-Resistant or Waterproof Layers: Durable coatings or membranes block out rain while still letting vapor escape.
- UV-Resistant Protection: Mold thrives in shaded, damp areas. A UV-resistant cover not only protects your furniture but also helps dry out lingering moisture faster.
- Tailored Fit: Flimsy or loose-fitting covers can sag and collect water. Custom covers or custom tarps ensure a snug fit with no pooling.
- Reinforced Seams and Vents: Look for double-stitched seams and built-in ventilation flaps. These features improve airflow and stop mold before it starts.
From a full selection of high-quality outdoor furniture covers including outdoor cushion covers, patio table covers, to BBQ covers, and outdoor storage covers, you can easily find the covers that are engineered to withstand the elements while staying breathable and strong.
Quick Mold Prevention Checklist
