awning maintenance

Awnings are a fantastic addition to any home or business, adding style, functional shade, and protection from the elements. But without proper maintenance, they can quickly lose their appeal and lifespan. Cleaning awnings might seem like a daunting task, but with the right tools, techniques, and tips, you can keep your awnings looking as fresh as the day they were installed. 

This guide will walk you through the proper steps for cleaning fabric awnings and provide valuable awning maintenance tips. We’ll break down the process into simple steps, helping you keep your awning in top condition. At M&M Sign & Awning, we install beautiful awnings and believe in helping you care for them properly.

Why Regular Awning Maintenance is Important 

Awnings are exposed to all kinds of weather, from bright sunshine to heavy rain. They can easily accumulate dirt, mold, mildew, bird droppings, and debris. Without regular maintenance, such buildup can lead to irreversible damage and even affect the material’s functionality. 

Here’s why cleaning your awnings should be a regular part of your upkeep routine:

  • Extend Lifespan: Regular cleaning prevents deterioration caused by dirt, stains, and mildew. 
  • Enhance Curb Appeal: Clean awnings keep your home or business looking polished and inviting. 
  • Preserve Material Quality: Over time, grime and debris can weaken the material, leading to tears or discoloration. 
  • Prevent Mold and Mildew: Mold and mildew not only damage materials but can also create health issues if left untreated.

Gather the Right Tools and Supplies 

Before you begin cleaning fabric awnings, gather your supplies. Whether you are cleaning a shade over a Haven Room, a sail shade in your backyard, or a large country club terrace awning, you’ll need:

  • Soft-bristle brush: Avoid anything too stiff that could damage the fabric.
  • Hose with a spray nozzle: for rinsing. A garden hose is usually sufficient.
  • Bucket(s): For mixing cleaning solutions.
  • Mild soap: Dish soap (like Dawn) or a specialized awning cleaner. Always choose non-detergent, biodegradable options. Avoid harsh household cleaners, bleach, or ammonia.
  • White vinegar (optional): For stubborn mildew stains.
  • Ladder or extension pole: To reach high areas safely.
  • Safety glasses and gloves: for your protection.
  • Microfiber cloths or sponges: for applying cleaner and wiping.
  • Leaf blower or broom (optional): To remove loose debris first.

Determine Your Awning Material 

Not all awnings are created equal, and the cleaning process can vary based on the type of material. Knowing your awning type is crucial. 

Fabric Awnings 

Fabric awnings (commonly made from polyester, canvas, or acrylic) require gentle cleaning to avoid damaging fibers. 

Metal Awnings 

Metal awnings, often made of aluminum or steel, can handle more robust cleaning techniques but still need care to prevent scratches or rust. 

Retractable Awnings 

Retractable awnings need occasional deep cleaning and care to avoid mechanisms from jamming due to dirt buildup.

Step-by-Step Guide to Cleaning Your Awnings 

Follow these detailed steps for a spotless finish.

  • Step 1: Gather Your Cleaning Supplies 

To ensure an effective cleaning process, you’ll need the following items: a soft-bristled brush, mild soap or specialized awning cleaner, a bucket of warm water, a garden hose with a spray nozzle, and a clean microfiber cloth or sponge. For metal awnings, you might also have a non-abrasive cleaner and a rust remover on hand if necessary.

  • Step 2: Remove Loose Debris 

Begin by removing any loose dirt, leaves, or other debris from the surface of the awning. For fabric awnings, use a soft-bristled brush to gently sweep away particles, being cautious not to damage the fabric. For metal awnings, a soft cloth or brush will suffice to dislodge dirt without leaving scratches.

  • Step 3: Prepare the Cleaning Solution 

Mix a solution of warm water and mild soap in a bucket. Avoid using harsh chemicals or bleach, as these can damage the material or strip away protective coatings. If you have a specialized cleaner designed for your awning type, follow the manufacturer’s instructions for best results.

  • Step 4: Scrub the Awning 

Dip your brush or sponge into the cleaning solution and start scrubbing the awning in small sections. For fabric, work in gentle circular motions to avoid tearing the material. On metal awnings, address any stubborn grime carefully, and be sure to clean around hinges and joints if it’s a retractable awning.

  • Step 5: Rinse Thoroughly 

After scrubbing, use a garden hose with a spray nozzle to thoroughly rinse the awning. Ensure all soap residue is removed, as leftover cleaner can degrade materials or attract more dirt over time. Be systematic and avoid missing any areas.

  • Step 6: Allow the awning to dry. 

Allow the awning to air dry completely before retracting or using it again. For fabric awnings, this prevents mold and mildew formation, and for metal awnings, it helps avoid water spots or rust.

  • Step 7: Inspect and finish. 

Once the awning is clean and dry, inspect it for any remaining dirt, stains, or damage. For metal awnings, apply a rust preventive if necessary. Retractable awnings may also benefit from a quick check of their mechanisms to ensure smooth operation.

These steps will keep your awnings looking good and working well for longer.

Pro Tips for Awning Maintenance 

Keeping your awnings clean in the long term means going beyond occasional scrubbing. 

  • Schedule Regular Cleanings: Clean your awnings at least twice a year for optimal results or more frequently if exposed to high pollution or harsh weather.
  • Use Protective Coatings: Consider using a UV-protectant spray to prevent discoloration and fading on fabric awnings.
  • Roll Up During Bad Weather: When possible, retract your awnings during storms, heavy rain, or snowfall to prevent undue strain or damage.
  • Retract During Bad Weather: Always retract your awning (if it’s retractable) during strong winds, heavy rain, hail, or snow. This is the single most important rule for preventing damage.
  • Clean Spills Immediately: Just like indoors, spills on your awning should be cleaned as soon as possible to prevent permanent staining.
  • Clear Debris Regularly: Even between deep cleans, quickly brush off leaves, dust, and pollen to prevent buildup.
  • Avoid Harsh Chemicals: Stick to mild, non-detergent soaps. Bleach and abrasive cleaners can strip protective coatings and weaken fabric.
  • Store Properly (if removable): If you have a removable awning, ensure it is completely clean and dry before storing it in a cool, dry place for the off-season.

By following these simple steps for how to clean awnings and integrating them into your routine awning maintenance, you’ll keep your outdoor living space beautiful and protected for many seasons to come.
