Awnings are a great way to add shade and style to your outdoor space, but they can quickly accumulate mold and mildew if not properly maintained. Mold thrives in humid and damp environments, making awnings the perfect spot for it to grow. Fortunately, cleaning your awning and removing mold doesn’t have to be complicated. This guide will take you through the process step-by-step to help restore your awning and keep it looking fresh for longer.
Tools You’ll Need

Before you get started, make sure you have everything you need for the job:
- Step Ladder : For safely reaching high awnings.
- Soft Bristle Brush : To scrub without damaging the fabric.
- Bucket : For mixing your cleaning solutions.
- Garden Hose : To rinse everything off after cleaning.
- Mild Soap or Detergent : A gentle solution for cleaning.
- Mold Remover : For tough mold stains.
- Rubber Gloves : To protect your hands from cleaning solutions.
- Protective Sheet/Tarp : To catch any cleaning solution spills and protect surrounding items.
Step-by-Step Process for Cleaning Mold from Your Awning
Step 1: Get Your Area Ready
Preparing the area around your awning is the first important step. You’ll want to make sure everything is set up for safe and effective cleaning.
How to prepare:
- Move any items under the awning: Remove furniture, plants, or anything that could get wet or be damaged during cleaning.
- Lay down a protective tarp or plastic sheet: Place a plastic sheet or tarp on the ground beneath the awning to catch any cleaning solution drips. This will protect the surface and surrounding items.
- Set up a stable ladder: Ensure your ladder is securely positioned for safe access to the entire awning.
Tip: If you have a retractable awning, especially a motorized one, make sure you understand whether your awning is manual or motorized and how an awning operates before starting the cleaning process.
Step 2: Brush Off Loose Dirt and Debris

Before applying any cleaning solution, it’s essential to remove loose dirt and debris from the awning’s surface. This step helps prevent dirt from mixing into your solution and ensures better results.
What to do:
- Use a soft-bristle brush or broom: Gently sweep off leaves, twigs, dirt, and cobwebs.
- Work from top to bottom: Start at the top of the awning and brush down to avoid pushing dirt further into the fabric.
- Focus on the edges and corners: These areas often collect more debris and need extra attention.
Tip: A vacuum with a soft brush attachment is perfect for removing deeper dust and debris, especially if you have a large awning or hard-to-reach spots.
Step 3: Hose Down the Awning

Now that the surface is free of debris, it’s time to wet the fabric. Hosing it down will help loosen dirt, mold, and grime, making it easier to apply the cleaning solution.
What to do:
- Spray the entire awning: Focus on areas that are moldy or heavily soiled.
- Ensure the fabric is thoroughly wet: This will help the cleaning solution spread evenly and work more effectively.
Tip: If you don’t have a hose, you can use a large sponge or cleaning cloth soaked in water. However, using a hose is quicker and more effective for large areas.
Step 4: Prepare Your Cleaning Solution

With the awning damp, it’s time to prepare your cleaning solution. Depending on the level of mold, you’ll need a mild soap solution for general cleaning, or a bleach solution for stubborn mold.
What to mix:
- For general cleaning: Mix 1 gallon of water with ¼ cup of mild soap or detergent.
- For mold: Mix ½ cup of bleach with 1 gallon of water.
Tip: Always test your solution on a small, hidden area of the awning to ensure it doesn’t cause discoloration or damage to the fabric.
Step 5: Apply the Cleaning Solution

Now that your cleaning solution is ready, it’s time to apply it to the moldy areas. Make sure to cover the entire affected area and allow the solution to break down the mold and grime.
- Dip your soft-bristle brush or sponge into the cleaning solution and gently scrub the moldy areas.
- Work the solution into the fabric, focusing on spots where mold or mildew are visible.
- Allow the solution to sit for 15–20 minutes so it can loosen the mold.
Tip: Don’t rush this step. Letting the cleaning solution soak in allows it to break down the mold more effectively and makes scrubbing easier.
Step 6: Scrub the Mold Stains

After the solution has soaked in, it’s time to scrub away the mold. This is where the cleaning solution will work its magic and lift the stains from the fabric.
- Use a soft-bristle brush to scrub the affected areas, applying gentle pressure to avoid damaging the fabric.
- Scrub in circular motions to help lift the mold and grime from the surface.
- Focus on the mold stains, but be sure to scrub the entire surface for an even clean.
Tip: If the mold is persistent, apply more cleaning solution to the area and scrub again. Some stains may require multiple cleanings.
Step 7: Rinse Thoroughly

Once you’ve scrubbed the awning, it’s important to rinse away any soap, bleach, or mold remover residue to ensure it doesn’t attract dirt or cause further damage.
- Use your garden hose to rinse the entire awning thoroughly, ensuring all cleaner is washed away.
- Continue rinsing until the water runs clear, indicating that all cleaning residue has been removed.
Tip: Rinse the awning well, as any leftover cleaner could cause discoloration or mold regrowth.
Step 8: Dry the Awning Completely

The final step is drying the awning completely. Storing or rolling up a wet awning can lead to mold regrowth, so make sure it is fully dry before retraction.
- Leave the awning fully extended to air dry. Sunlight will help speed up the process.
- Ensure the awning is completely dry before you retract it, as moisture can lead to more mold.
Tip: Try to dry the awning in direct sunlight. UV rays not only help with drying but also kill any remaining mold spores.
Maintenance Tips to Prevent Future Mold Growth
To keep your awning clean and mold-free, follow these easy maintenance tips:
- Routine cleaning: Hose down your awning once a month to remove dirt and debris before it has a chance to build up.
- Apply fabric protectant: After cleaning, use a fabric protectant spray to keep water from soaking in and preventing mold.
- Proper storage: Always ensure the awning is dry before retracting or storing it.
- Regular inspections: Check your awning for mold, especially after rainy or humid weather.
