Fabric vs. Metal Awnings: How Cleaning Methods Differ and Why It Matters
Awnings shield entryways from rain and sun, but they also collect dirt, mildew, and bird droppings. Choosing the wrong cleaning method can shorten their lifespan or void a warranty. Below, we compare best practices for fabric and metal awning cleaning so you can protect your investment and keep your storefront or patio looking sharp.
1. Fabric Awnings: Gentle Chemistry Over High Pressure
Common Materials
Most residential awnings are woven acrylic, polyester, or canvas. These porous fibers can fray when blasted with water at more than 500 PSI.
Cleaning Process
- Dry brush loose debris to prevent stains from embedding during rinsing.
- Mix a mild soap (like dish detergent) with lukewarm water and apply using a soft brush in circular motions.
- Let the solution dwell for 10 minutes, then rinse at garden-hose pressure.
- Air-dry fully before retracting to prevent mold.
Why It Matters
High-pressure washing forces water into seams, weakening stitching and promoting mildew inside the roll. A gentle approach extends fabric colorfastness and safeguards manufacturer warranties.
2. Metal Awnings: Controlled Pressure With Alkaline Degreasers
Common Materials
Aluminum and galvanized steel are popular for commercial awnings because they resist rot but can oxidize or chalk over time.
Cleaning Process
- Apply an alkaline degreaser diluted per label—this lifts greasy deposits without etching paint.
- Agitate stubborn spots with a nylon pad.
- Rinse at 1,500-2,000 PSI, keeping the nozzle 12 inches from the surface to avoid denting thin panels.
- Finish with a wax or polymer sealant to slow future oxidation.
Why It Matters
Too low pressure leaves grime; too high pressure can warp metal or strip powder-coat finishes. Controlled pressure restores shine while protecting structural integrity.
3. Shared Pitfalls to Avoid
- Bleach on Fabric: Can yellow acrylic threads and weaken UV coatings.
- Wire Brushes on Metal: Scratch protective paint, speeding corrosion.
- Ignoring Runoff: Dirty rinse water can stain the siding below unless captured or redirected.
When to DIY—and When to Call the Pros
DIY soap-and-hose kits are fine for light pollen on a porch awning, but grease-stained canopies above busy patios usually need commercial hot-water rigs and pro-grade detergents. A trained crew secures ladders, reclaims wastewater, and spots early fabric tears or loose brackets before they become costly repairs—advantages no store-bought kit can match.
