Outdoor furniture covers are a great way to protect your patio sets, grills, and other outdoor items from the elements. However, just like your indoor fabrics, outdoor covers can get dirty over time from exposure to the weather, pollen, dirt, and other debris. Learning how to properly wash your outdoor covers will help extend their life so you can enjoy them for many seasons to come.
Supplies Needed
Washing outdoor furniture covers doesn’t require any special equipment. You likely already have most, if not all, of the supplies you’ll need around the house. Here’s a quick list:
- Medium to large plastic tub or bin
- Mild laundry detergent
- Soft scrub brush or sponge
- Garden hose with spray nozzle
- Old towels or cloth rags
You’ll also want to spot clean any extra dirty areas first before washing, so have some all-purpose cleaner or stain remover on hand too.
Pre-Treating Stained Areas
Before fully washing your outdoor covers, inspect them closely and spot treat any stained or heavily soiled areas. This extra step helps ensure the stains don’t set further when washing.
Here are some common problem areas to check for on outdoor furniture covers:
- Edges or hems: These often drag on patios and pick up dirt. Spot clean mud or grime.
- Areas touching furniture: Check where the cover lays on tables or chair arms as debris can collect there.
- Seat and back: Pollen and other particles settle on upward facing surfaces. Pre-treat any visible stains.
- Underneath: Don’t forget to check the underside of covers too if they’ve been on the ground at all.
Supplies you’ll want for spot cleaning:
- Small scrub brush
- Terry cloth rag
- All-purpose cleaner or stain remover
- Small bowl of water
Dip the brush into the cleaner and gently scrub stains on the cover. Use a damp rag to blot away any excess dirt. For tougher stains, let the cleaner sit for 5 minutes before scrubbing. This helps lift the stain from the fabric.
Repeat this process in all visibly soiled areas before washing. This prevents stains from setting during the wash cycle.
Washing Covers in a Tub
For most outdoor furniture covers, washing them in a large tub by hand is simple and effective.
Step 1: Fill Tub
Select a plastic laundry tub, storage bin, or other container large enough to hold the cover flat. Fill the tub 3⁄4 full with cool water.
Step 2: Add Detergent
Pour a small amount of mild laundry detergent into the wash water, about 1⁄4 cup. Swish the water around to dissolve and mix it.
Step 3: Immerse Cover
Fully immerse the furniture cover in the wash water. Push it below the surface and let it soak for 15-20 minutes. This gives the detergent time to lift dirt from the fabric.
Step 4: Agitate
After soaking, lift, drain, and submerge sections of the cover, swishing it around in the water. Use your hands or a soft-bristled scrub brush to gently agitate the fabric. This releases ingrained dirt and grime from the material.
Focus on scrubbing the hem, underside, and any still-stained areas. Avoid harsh scrubbing which can damage the cover.
Step 5: Rinse
Once washing is complete, fully drain the dirty wash water from the tub. Thoroughly rinse the cover with clean water using a garden hose or by refilling the tub.
Continue rinsing until all suds are removed. This prevents detergent residue from remaining on the fabric.
Step 6: Air Dry
When thoroughly rinsed, remove excess moisture from the cover by laying it flat on deck railing, patio table, or clothesline. Allow it to fully air dry in the sun before putting back on your outdoor furniture.
Turn the cover over halfway through drying so both sides fully dry. The sun’s UV rays help naturally sanitize the fabric too.
Using a Washing Machine
For especially large or heavily soiled furniture covers, washing them in a household washing machine may be easier than hand washing.
Step 1: Shake Off Debris
Before placing in the washer, take the cover outdoors and vigorously shake it to remove any loose dirt, leaves or debris. This prevents clogging the machine.
Step 2: Pre-treat Stains
Spot clean any visible stained areas on the cover by hand before machine washing. This prevents stains from setting further.
Step 3: Wash on Gentle Cycle
Place the cover in the washing machine set to a gentle or delicate cycle using cool water. Avoid using hot water which can damage fabric.
Step 4: Use Mild Detergent
Only use a small amount (1-2 tbsp) mild, high efficiency laundry detergent. Harsh detergents may fade or deteriorate the fabric cover.
Step 5: Air Dry
When the wash cycle finishes, avoid placing covers in the dryer which can damage them. Remove promptly and hang to air dry fully in the sun.
Cleaning Polyester vs. Cotton Covers
The washing method you use may vary slightly depending on the material of your outdoor furniture covers. Here’s how to wash the two most common types:
Polyester
Polyester blends are popular for their water-resistance and durability. Keep these tips in mind when cleaning:
- Check tag to confirm washing instructions.
- Machine washing is fine for most polyester covers.
- Wash in cool water on a gentle cycle. Polyester risks heat damage.
- Line dry or tumble dry on low when almost fully dry.
Cotton
100% cotton covers should be washed more gently by hand. Follow these tips:
- Handwash only to protect the cotton fibers.
- Wash in cool water to prevent fading.
- Gently scrub stains with a soft brush. No bleach.
- Reshape while wet and line dry fully before storing.
Cleaning Waterproof Outdoor Covers
Water-resistant outdoor furniture covers require a bit more care when washing. Here are some tips:
- Spot clean stains when possible instead of full washing.
- Handwash only, no machine washing which can reduce water repellency.
- Use a very mild detergent and wash gently with a soft sponge.
- Rinse thoroughly – detergent residue affects water beading.
- Lay flat and reshape while cover is still wet.
- Line or air dry fully before putting back on furniture.
Take extra care not to use harsh cleansers or scrub brushes when washing coated covers. This maintains the water resistant properties. Spot clean or hand wash only when needed.
Preventing Mildew on Covers
To help prevent mildew growth on outdoor furniture covers, follow these tips:
- Wash regularly to remove dirt before it builds up.
- Allow covers to fully dry after washing and before storing.
- Use white vinegar in the rinse cycle to inhibit mildew.
- Spray covers with lemon juice diluted in water and let dry in sun.
- Check for mildew spots monthly and treat promptly with vinegar.
- Consider mildew-resistant covers if storing furniture long-term outdoors.
Storing Clean Covers
After properly washing and drying your outdoor furniture covers, make sure you store them correctly between uses. Here are some storage tips:
- Fold neatly along seams to avoid creasing.
- Place folded covers in a dry plastic bin or tote, not an outdoor shed.
- Store indoors in a closet or basement to prevent re-soiling.
- Prevent excess moisture – wipe off furnishings before re-covering.
- Check periodically for mildew if storing long-term.
Proper storage preserves your cover’s lifespan and appearance over many seasons. Make washing and drying completely a habit before storage.
When to Replace Covers
With periodic washing and proper storage, most standard outdoor furniture covers will last approximately 2-3 years before needing replacement.
Signs it’s time to replace a cover include:
- Fabric has become thin, worn or developing holes.
- Cover is no longer water resistant.
- Discoloration that doesn’t wash out.
- Mildew stains that reappear quickly.
- Straps and grommets are ripped or detached.
Purchasing quality replacement covers and washing them regularly extends their durability significantly. With proper care, outdoor furniture covers can often last 5+ years.
Common Outdoor Furniture Cover FAQs
Wondering how to keep your outdoor furniture covers clean in between full washes? Or not sure if it’s safe to machine wash certain fabrics? Here are answers to some frequently asked questions:
How do I clean pollen off covers between washes?
- Use a soft bristle brush or vacuum attachment to gently remove excess pollen if heavy buildup occurs. Wipe lightly with a damp cloth. Allow to fully dry.
Can I pressure wash my covers?
- Avoid pressure washing. The intense water pressure can damage fabric, seams and straps. For a deeper clean, hand wash instead.
How do I get mold off a cover?
- Mix equal parts vinegar and water in a spray bottle. Lightly spray problem areas and let sit 10 minutes. Wipe with a soft brush and rinse clean.
What’s the best way to clean velcro straps?
- Use an old toothbrush and rubbing alcohol to scrub debris from velcro straps as needed. Allow to fully dry after cleaning.
How should I clean canvas covers?
- Spot clean stains on canvas with mild soap and water. For a deeper clean, handwash in cool water and line dry completely before storing.
Can I put my polyester cover in the dryer?
- It’s best to line or air dry polyester covers to prevent heat damage. If machine drying, use air only on a very low temperature setting.
Get Your Covers Clean for Spring
If you’re ready to enjoy your outdoor living spaces again after winter storage, make sure to start the season off right by washing all your furniture covers first.
A thorough cleaning removes built up dirt, grime, and mildew that accumulated over winter. Your freshly washed covers will again provide the maximum protection for your patio and deck furnishings through the new season.
These steps on properly washing outdoor furniture covers take out stains, inhibit mildew growth, and extend the lifespan of your covers. Just be sure to allow adequate time for full air drying in the sun before placing them back on clean furniture ready to enjoy.
