Methods In Cleaning The Green Mildew From Patio Umbrella

At the beach, garden, poolside, and over outdoor dining tables, patio umbrellas give the shade we want. They become dirty from dust and air pollution, not to mention tree sap and bird droppings, because they are exposed to different kinds of germs for months at a time.

Canvas, solid or mesh vinyl, and specialist materials that resemble straw or thatch can all be used to make outdoor umbrellas. Most residential umbrellas are constructed of treated acrylic fabrics (such as Sunbrella) that resist moisture, stains, and mildew.

Even the best materials are contaminated by airborne muck, touched by sunscreen-coated hands, and attacked by birds. When these particles become embedded in the fibers, they leave ugly stains that can mildew if exposed to moisture.

Cleaning your umbrella on a regular basis throughout the sunny season, and especially before slipping on the cover or storing it away for the off-season, is the key to keeping it looking its best.

 

Method #1. Basic cleaning

Follow these procedures to restore the appearance of your outdoor umbrella if it is covered in grime or has unattractive mildew stains.

Step #1. Remove any loose dirt and debris, such as leaves, with a soft bristle brush.

Step #2. Wash the fabric of the umbrella canvas with a gentle detergent diluted in warm water and a soft bristle brush, scrub in sections in circular motions.

Step #3. Allow the umbrella to sit for 15 minutes after cleaning the entire surface area to release the dirt and grime.

Step #4. Rinse the surface with a hose to ensure that any soap residue is removed.

Step #5. Allow the fabric to dry completely in the sun before storing it.

 

Method #2. Deep cleaning

Outdoor umbrellas are susceptible to mildew and mould growth, especially if left outside all year or stored moist. Start by following these methods to remove mildew from an outdoor umbrella:

Step #1. Remove any loose dirt with a soft bristle brush and scrub the areas with mould or mildew thoroughly.

Step #2. Combine equal amounts white vinegar and warm water in a bucket. 

Step #3. Dip the brush into the solution and work in small areas on the canvas in a circular motion.

Step #4. Repeat until the mildew and mold are no longer visible.

Step #5. Allow to dry in the sun after rinsing the surface with a hose.

Step #6. For a general clean, repeat the steps above if necessary.

 

Method #3. Cleaning with solution

Step #1. Make your way to a shady spot. Move an umbrella with an unibody design cloth top to a shady spot away from direct sunshine to clean it.

Step #2. Remove any loose dirt using a brush or vacuum. To avoid forcing the soil deeper into the cloth, use a soft-bristled brush.

Step #3. Make a cleaning mixture by mixing 1/4 cup of detergent and a gallon of lukewarm water. Dishwashing liquid should be avoided in favor of laundry detergent. 

You’ll have less bubbles to rinse away, and a top grade enzyme-based detergent like Tide or Persil will break up stains the best.

Step #4. Scrub the dirt away and work the solution into the cloth in circular motions with a soft-bristled brush. Apply some extra elbow grease and focus on the discoloured areas. 

Some stains, such as sunscreen, may necessitate additional treatment steps. This article on how to get mildew smell out of carpet padding will give you effective steps on deodorizing your umbrella.

Step #5. Allow the solution to take effect. Allow the concentration to seep into the fabric and perform its work of loosening the soil for 15 to 20 minutes. 

Step #6. Remove the umbrella and rinse the fabric well with a hose sprayer to eliminate all soap residue. It will actually draw more soil if you leave it soapy.

Step #7. Return the umbrella to a sunny location and air dry the cloth. Close the umbrella after it has completely dried.

 

How Often Should Outdoor Umbrellas Be Cleaned?

When in use, all outdoor/patio umbrellas should be cleaned at least once a month.  If your patio umbrella is near trees or tall shrubs, you may need to clean it more frequently.

 

Conclusion

It’s necessary to clean your patio umbrella on a regular basis because it’s exposed to sun, rain, dirt, trash, and pollutants such as bird droppings and tree sap. Umbrellas should be stored underneath and sheltered from the rain while not in use, such as during the offseason. 

If you’re going to store your umbrella after it’s been used, make sure it’s totally dry to avoid mildew growth. Brush off dirt, debris, and cobwebs on a regular basis to maintain your outdoor umbrella looking beautiful and extending its longevity. 

If your umbrella is near tree foliage, you should do this at least once a month, if not more. Allow mildew, sunscreen, or greasy leaves to sit for long periods of time to avoid discoloration. 

Instead, follow the care instructions and methods listed above. That would be all on how to remove green mildew from patio umbrella.
