Understanding Mildew and Sunbrella Fabric
What is Mildew?
Mildew is a type of fungus that thrives in warm, damp conditions. It appears as a thin, superficial growth consisting of minute hyphae (fungal filaments) on various types of organic material.
Mildew is commonly found on fabric, paper, leather, and any surface where moisture and warmth are present. Its appearance can range from white to black and it often gives off a musty smell.
Conditions Fostering Mildew Growth
The growth of mildew is most prolific in environments with high humidity, limited airflow, and temperatures ranging between 77°F and 88°F.
However, it can also occur at lower temperatures and in less humid conditions if the material remains damp. Mildew can cause discoloration and damage to your cushions, and it can be harmful to your health if not addressed promptly.
Properties of Sunbrella Fabric
Sunbrella fabric is known for its durability and resistance to the elements. It is made from acrylic fibers that are water-resistant, making it an ideal choice for outdoor furniture.
Sunbrella is designed to resist fading, staining, and degradation from sunlight and chemical exposure. Despite these resistant properties, mildew can still form on the fabric if organic material like dirt and leaves are left on the surface.
Preventing Mildew Through Regular Maintenance
Regular maintenance of Sunbrella cushions is crucial in preventing mildew growth. It involves keeping the fabric clean, dry, and free from organic debris.
Periodic cleaning, along with proper storage and use of protective covers, can significantly reduce the risk of mildew formation on your cushions.
Preparing to Clean Your Sunbrella Cushions
Removing and Assessing Cushions
Begin by removing your Sunbrella cushions from their respective furniture. Examine each cushion for signs of mildew, taking note of the severity and areas affected. This will help you determine the cleaning approach and the amount of cleaning solution needed.
Gathering Cleaning Supplies
Collect the necessary supplies for cleaning your cushions. This includes mild, non-detergent soap, bleach, a soft bristle brush, a vacuum cleaner with an upholstery attachment, gloves, and protective eyewear.
Ensure you have a hose or buckets of water for rinsing.
Creating a Cleaning Area
Choose a well-ventilated outdoor space to clean your cushions. This area should be free of dirt and debris to prevent re-contamination during the cleaning process. If working on a patio or deck, protect the surface with a plastic drop cloth.
Pre-Cleaning Steps
Before applying any water or cleaning solution, brush off loose mildew spores and debris from the fabric’s surface.
This will help to prevent the spread of mildew and make the cleaning solution more effective.
Step-by-Step Cleaning Process
Vacuuming the Cushions
Step one involves vacuuming the cushions with an upholstery attachment to remove any remaining loose particles. This step is crucial for getting rid of dirt and debris that could harbor mildew spores.
Preparing the Cleaning Solution
Mix a cleaning solution of mild soap and warm water. For more severe cases of mildew, prepare a stronger solution using 1 cup of bleach and ¼ cup of mild soap per gallon of water. Always wear gloves to protect your hands when working with bleach.
Applying the Cleaning Solution
Apply the cleaning solution to the cushions, ensuring all areas affected by mildew are covered. Use a spray bottle for even application or a clean cloth to dab the solution onto the fabric.
Gentle Scrubbing
With a soft bristle brush, gently scrub the cushions. Focus on the areas with visible mildew but also cover the entire surface to prevent any unseen spores from growing.
Soaking the Fabric
Allow the cleaning solution to soak into the Sunbrella fabric for 15 to 20 minutes. This soaking period is essential for the solution to penetrate and kill the mildew spores.
Rinsing the Cushions
Rinse the cushions thoroughly with clean water to remove all traces of soap and bleach. Make sure that no cleaning solution remains as it could attract dirt or damage the fabric.
Drying the Cushions
After rinsing, dry the cushions completely in a well-ventilated area or in direct sunlight. Sunlight is a natural mildew inhibitor and will help ensure that your cushions are as mildew-free as possible.
Additional Cleaning Steps if Needed
If mildew persists after the initial cleaning, consider using a commercial mildew remover, following the manufacturer’s guidelines.
For persistent stains or concerns, contact the manufacturer or consult their cleaning guidelines. Always test a small, inconspicuous area first to ensure colorfastness and fabric integrity.
