Mold can be a common problem for outdoor cushions. Left outside and exposed to moisture, cushions can easily develop mold growth. While unattractive and potentially unhealthy, mold on outdoor cushions can be removed with some simple cleaning methods. This comprehensive guide will provide tips and step-by-step instructions for effectively cleaning mold off outdoor cushions.
What Causes Mold on Outdoor Cushions?
Outdoor cushions provide comfortable seating options for porches, patios and poolside areas. However, being situated outside leaves them susceptible to moisture. Mold needs moisture to grow, so outdoor cushions are prone to developing mold. Here are some common reasons mold can start growing on outdoor cushions:
- Exposure to rain and sprinklers – Getting wet from rain, irrigation systems or sprinklers provides ample moisture for mold. Even brief exposure can be enough for spores to take hold and spread.
- High humidity – Humid conditions are ideal environments for mold. The moisture in the air condenses on cushions, giving spores moisture to grow.
- Lack of sunlight – Shaded areas prevent sunlight from drying cushions. Prolonged dampness allows mold colonies to become established.
- Infrequent cleaning/drying – Not regularly cleaning or drying cushions gives mold time to grow undisturbed in dirt, debris and moisture.
Preventing mold on outdoor cushions involves keeping them clean and dry. But even with precautions, mold can sometimes form. When it does, prompt cleaning is required to remove it.
How to Identify Mold on Cushions
Detecting mold early makes removal easier. Here are signs to look for:
- Spots or discolored patches – Mold growth often starts as small spots or patches of black, green, brown, yellow, orange or grey.
- Musty odor – A strong mildew or musty smell can indicate mold is present.
- Visible fuzz or growth – More advanced mold may have a velvety or fuzzy appearance.
- Moisture – Damp or wet spots prone to mold should be investigated for spores.
Check undersides and seams carefully, as mold often starts in hidden crevices. If detected early, mold can be treated before extensive growth occurs.
Dangers of Mold on Cushions
Mold may seem like just a cosmetic nuisance, but it can pose some health concerns:
- Allergic reactions – Mold spores can trigger respiratory issues like sneezing, runny nose or irritated eyes. Severe allergies are possible in sensitive individuals.
- Asthma aggravation – Those with asthma may experience coughing, wheezing or difficulty breathing when exposed to mold.
- Toxin exposure – Some types produce mycotoxins that irritate the skin, eyes and airways. Toxins can also accumulate over time.
- Infection susceptibility – Mold exposure may make people more prone to respiratory infections like bronchitis.
- Musty odors – Smells can be unpleasant and difficult to eliminate from cushions.
Cleaning mold promptly not only improves cushion appearance, but also reduces potential health effects.
How to Clean Small Amounts of Mold
If mold growth is minimal, gentle cleaning methods may be effective for removal. Here are some simple approaches:
Baking Soda Paste
Baking soda’s gritty texture and alkaline properties make it useful for scrubbing away mold.
What You Need:
- Baking soda
- Water
- Small bowl
- Soft brush or sponge
Directions:
- In a small bowl, mix 3 tablespoons of baking soda with just enough water to form a spreadable paste.
- Using a soft brush or sponge, apply the paste directly to mold spots.
- Gently scrub to lift mold away from cushions. Take care not to rub too vigorously.
- Wipe area with a clean, damp cloth and allow to fully dry before using cushions.
Baking soda paste provides effective spot cleaning for minor mold growth. Rinse well after use.
White Vinegar Spray
As a mild acid, white vinegar can help destroy mold spores and remove buildup.
What You Need:
- White vinegar
- Spray bottle
Directions:
- Fill spray bottle with undiluted white vinegar.
- Lightly spray vinegar directly onto moldy areas, completely saturating spots.
- Let vineagar sit for 1 hour before wiping with a clean cloth. No need to rinse.
- Allow cushions to fully air dry before using again.
The acetic acid in vinegar kills mold spores on contact. Repeat applications may be needed for stubborn growth.
Hydrogen Peroxide
Hydrogen peroxide is another household item that destroys mold through oxidation.
What You Need:
- 3% hydrogen peroxide
- Spray bottle
Directions:
- In a spray bottle, mix equal parts hydrogen peroxide and water.
- Lightly spray solution onto moldy spots.
- Allow to sit for 10-15 minutes before wiping clean with a damp cloth.
- No rinsing needed. Let dry completely before reuse.
Hydrogen peroxide bubbles away mold and helps bleach discoloration. Use caution on colored cushions as it may lighten dyes.
Cleaning Extensive Mold Growth
For more severe mold infestations, stronger cleaners and thorough scrubbing is required:
Borax Solution
Borax has natural antifungal abilities to eliminate mold and stop regrowth.
What You Need:
- 1 cup borax powder
- 2 gallons warm water
- Bucket
- Stiff scrub brush
Directions:
- Dissolve 1 cup borax in 2 gallons warm water in a bucket.
- Submerge cushions in solution or use scrub brush to liberally apply to moldy spots.
- Aggressively scrub all affected areas until mold is removed.
- Rinse cushions thoroughly with clean water.
- Allow to completely air dry before reuse.
Borax solution is especially effective for mold that has progressed deeper into cushion fibers.
Chlorine Bleach
Bleach is a strong antimicrobial that kills and removes mold. Use caution as it may discolor fabrics.
What You Need:
- Chlorine bleach
- Water
- Spray bottle
- Rubber gloves
- Protective eyewear
Directions:
- In a spray bottle, mix 1 part bleach to 4 parts water.
- Wearing gloves and eye protection, spray bleach solution liberally on moldy areas.
- Allow to sit for 15 minutes before wiping clean with a damp cloth.
- Rinse surfaces thoroughly with clean water.
- Let cushions dry fully in sunlight before reuse.
Bleach is very effective but may lighten or discolor some fabrics. Spot test first. Provide adequate ventilation.
How to Dry and Prevent Mold Growth
Removing mold is only part of the process. Taking steps to dry cushions and prevent mold recurrence is key:
- Allow cushions to dry completely between uses and before storing.
- Wash removable covers frequently to eliminate dirt and debris mold feeds on.
- Brush off dirt and wipe up spills to deprive mold of moisture sources.
- Rotate cushions to promote even drying after rain or water exposure.
- Use fans to speed drying if humidity or dampness persists.
- Check for mold regularly, especially along seams and undersides of cushions.
- Clean spills immediately so moisture does not soak in.
- When not in use, store cushions in a clean, dry area protected from moisture.
- Avoid storing directly on concrete or damp surfaces. Use wood palettes or racks to allow airflow underneath.
With diligent care and prompt cleaning when needed, outdoor cushions can stay mold-free and ready to provide a comfortable place to relax outside. Maintaining a watchful eye and taking preventative measures helps cushions look their best season after season.
