How to Clean and Maintain Your House Awnings

Table of Contents

Your awnings on your home are a beautiful addition that gives you so many benefits of extra outdoor living space, cooling temperatures, energy efficiency, and they also keep both your indoor and outdoor furniture in pristine shape by protecting them from the sun’s UV rays that cause damage. Since your awning works so hard for you and your household, it just makes sense to keep it clean so it looks beautiful and performs for you for many years. Read on to find out exactly how to clean awnings and keep them in top shape, depending on the type you have.

How Often to Clean Your Awning

Anything that is kept clean just lasts longer, no matter what the item is, so it just makes sense that you should do a bit of maintenance on your outdoor awning too. Clean awnings are an essential part of maintaining your home’s exteriors.  Areas that have higher pollution rates in the city and areas in more rural areas with tree debris designate that you may need to clean awnings a bit more often. The process is simple and easy, though.

For the most part, awnings require very little care and should be cleaned at the beginning or end of the season when you use them most. This is usually during the warm months of the summer. A quick spray-off with a garden hose every so often makes the annual cleaning process quicker and easier. Retractable awnings require less care because when not in use, they roll up into a protective cassette where they mount above your porch, patio, or deck. This helps to keep the awning fabric cleaner all year round and resist wear and tear. Fixed awnings, however, may need to be cleaned a bit more often.

How To Clean Awnings - 4 Steps

Cleaning an awning requires special tools and techniques to avoid damaging its fabric or material, so let’s explore how we can effectively clean awnings. The basic steps are pretty much the same, effortless and quick to do.

  • Step 1: Fill a bucket with warm water and a bit of mild dish soap. Avoid using chemicals.
  • Step 2: Gently wipe down the frame and the fabric with a clean cloth or a soft, bristled brush. Let the dish soap do all the hard work for you and don’t get too industrious, or you can damage the canvas top.
  • Step 3: Let the awning dry naturally after rinsing it off with a garden hose. Never roll up a retractable awning while it’s wet, or it can damage it, lead to mold and mildew and a smelly situation.
  • Step 4: You can treat your awning with a waterproofing spray to freshen that layer up annually. It helps it to repel water and prevent mold and rotting to last for many years.

How To Clean Your Awnings According to Materials

Different materials require slightly different care to keep them in great shape, so it’s important to know how to clean awnings according to the material to avoid causing any damage.

Clean Awnings

How to Clean a Canvas Awning

Combine lukewarm water and 3 ounces of mild dish soap or laundry detergent. It doesn’t have to be measured precisely, but this equates to 6 tablespoons. Sweep off the canvas top with a broom to remove loose debris, twigs, pollen, or dirt. Wet the awning with a garden hose to dampen it. Dip a brush into the cleaning solution and scrub the awning using a circular motion with a soft bristle brush.

Work in small areas so the soapy solution doesn’t dry as you clean awnings. Use a garden hose to thoroughly rinse all the soapy mixture until the water running off is clear. Let your top canvas air dry completely. Repeat this process to clean the bottom side of the awning.

How to Clean A Vinyl Awning

To clean a vinyl awning, the preferred method is using a commercial awning cleaner approved for vinyl. First, use a broom to sweep any loose debris off, and then spray the cleaner in a mist from the spray bottle over the awning by starting from the bottom and working upward. Let the cleaner sit for a few minutes for it to work it’s magic, and then scrub it gently with a brush or sponge. Rinse it off thoroughly with a garden hose and allow it to thoroughly air dry. Repeat this process for the bottom side of the awning.

How to Clean an Acrylic Awning

Combine your mild soap for dishes or laundry soap with water in a bucket. Sweep off the loose dirt and debris with a broom, using a ladder if necessary. Wet the awning with a garden hose and then clean the top of the awning with a soft bristle brush or use a commercial cleaner that it approved for acrylic awnings. Rinse the soapy mixture off with a garden hose and allow it to air dry completely, then repeat the steps for the underside of the awning.

How to Clean an Aluminum Awning

Choose a solvent that is especially formulated for cleaning aluminum awnings. You can get this from a hardware store or from an awning supply store. Wet the awning very well with a garden hose and dip a brush into the solution of water mixture with cleaner mixed to the manufacturer’s instructions on the bottle and scrub the entire awning with it. Instead, you may use a spray bottle to apply the mixture.

Rinse the solution off with a garden hose and make sure it’s rinsed thoroughly until the water coming off is clear, so it doesn’t leave a soapy film on the aluminum. If the cleaner comes into contact with any other surfaces in the cleaning process, clean it off immediately with water. Clean the underside in the same manner and allow it to dry completely.

How to Clean an RV Awning

Open and extend your RV awning fully. Mix water and a mild detergent together, or use a commercial awning cleaner for fabric awnings. Sweep the top of the awning off with a broom, and then wet the awning with water from a hose on both the top and bottom sides.

Use a long-handled brush or a hand-held soft-bristled brush while standing on a ladder to scrub the awning on both sides, top and bottom with the cleaning solution. Roll the awning back up onto the protective cassette and let it soak for about 5 minutes. Open and extend the awning fully again, and use a clean sponge to wipe the top and bottom sides. Rinse the cleaner off with a hose and allow the RV awning to fully air dry before rolling it back up into the storage space.

Best Awning Cleaner for Every Type of Pollutant

Pollution and stains just happen, it’s a part of life. From bird droppings to odd ball things that get on your awning, it’s best to know what type of cleaner to use that works best based on the chemical compound of the pollutant.

Latext Paint
Oil based paint
Mold Stain
Rust Stains

Other Types of Stains

Clean automotive grease off with acetone or dish soap and water, and use dish soap for vinyl awnings. For all types of awnings, clean bird droppings off with dish soap and water. For stains caused by leaves, use water and ammonia and for tree pitch such as pine tree pitch, use dish soap and turpentine for all types except use a grease remover for aluminum.

Is Pressure Washing an Awning Recommended?

Your awning looks particularly dirty, or you don’t have a lot of time to clean it manually. So, you’re wondering if you can simply break out the pressure washer and be done with the task. This isn’t a recommended method of cleaning your awning, no matter what material it’s made of, and especially not a fabric awning. Professional awning cleaning services can adjust the pressure of the water on a power washer so as not to cause harm to your awning and use special cleaners as well.
