The Ultimate Guide to Cleaning a Rectangle Awning
A clean rectangle awning not only enhances your home’s curb appeal but also extends the fabric’s life, protecting your investment. Whether it’s canvas, vinyl, or polyester, this step-by-step guide will show you how to clean a rectangle awning effectively and safely, ensuring it looks great for years to come.
Why Regular Awning Cleaning is Essential
Before diving into the “how,” understand the “why.” Neglecting your awning leads to mold, mildew, and stain accumulation, which can degrade fabrics, cause permanent discoloration, and weaken the material. Regular cleaning prevents costly replacements and maintains the awning’s UV and water-resistant properties.
Step-by-Step Guide to Cleaning Your Rectangle Awning
Step 1: Safety First & Preparation
- Secure the Area: Ensure the area below is clear.
- Check the Weather: Pick a cloudy, mild day. Direct sun causes cleaners to dry too fast, leaving streaks.
- Gear Up: Wear gloves and eye protection.
- Dry Brush: Use a soft-bristle broom to remove loose dirt, leaves, and cobwebs from the top and underside.
Step 2: The Cleaning Solution
For most fabrics (canvas, polyester, acrylic): Mix a mild cleaner. Avoid harsh detergents, bleach, or abrasive cleaners unless the manufacturer specifies them.
- Eco-Friendly Option: ¼ cup mild dish soap (like Dawn) per gallon of warm water.
- For Mildew Stains: Add 1 cup white vinegar to the soapy mixture. For persistent mildew, a dedicated mold/mildew remover may be needed.
For Vinyl Awnings: Use the same soap mixture or a dedicated vinyl cleaner. Avoid solvents.
Step 3: Application & Scrubbing
- Pre-soak: Rinse the awning thoroughly with a garden hose on a gentle setting.
- Apply Solution: Using a soft brush (long-handled for reach) or a sponge, apply the cleaning solution. Work in manageable rectangle sections (e.g., 4×4 ft areas) to ensure even cleaning.
- Gentle Scrubbing: Scrub with gentle, linear motions. Never use a pressure washer on high setting, as it can damage fabric fibers and seams. If using one, keep it on the lowest, widest spray setting and maintain a safe distance.
Step 4: Rinsing & Drying
- Rinse Thoroughly: Rinse from the top down until all soap suds are gone. Soap residue attracts more dirt.
- Air Dry Completely: Allow the awning to dry fully before retracting. This is the most critical step to prevent mildew growth. Ensure it’s stretched taut to avoid water pockets.
Awning Material Cleaning Comparison Table
| Feature | Canvas/Acrylic | Vinyl/PVC | Polyester (Laminated) |
|---|---|---|---|
| Best Cleaning Agent | Mild soap, dedicated acrylic cleaner | Mild soap, dedicated vinyl cleaner | Mild soap, ammonia-free cleaner |
| What to Avoid | Bleach, harsh detergents, acid-based cleaners | Solvents, abrasive pads, acetone | Abrasive cleaners, bleach |
| Mildew Treatment | Vinegar/water solution; commercial mildewcide | Vinegar/water; stronger mildew removers | Vinegar/water; test cleaner in hidden area first |
| Key Consideration | Requires thorough rinsing; must dry completely | Easier to scrub; can handle slightly stronger cleaners | Often has a protective coating—gentle cleaning preserves it |
| Pressure Washer Safe? | Not Recommended (can fray fibers) | Caution (Low pressure only, from a distance) | Not Recommended |
Maintenance Schedule & Product Comparison Table
| Task | Frequency | Recommended Products/Notes |
|---|---|---|
| Dry Brushing | Weekly / Bi-Weekly | Soft-bristle broom or brush |
| Light Cleaning | Monthly | Garden hose rinse to remove surface dust and pollen |
| Deep Clean | 1-2 Times per Season (Spring & Fall) | Mild soap mix or products like 303 Fabric Cleaner, Star Brite Awning Cleaner |
| Mildew Treatment | As Needed | RMR-86 Instant Mold & Mildew Stain Remover, Concrobium Mold Control |
| Protective Treatment | After Deep Cleaning (Annually) | 303 Fabric Guard (for fabrics), 303 UV Protectant Spray (for vinyl) – re-establishes water repellency. |
Pro Tips for Stubborn Stains
- Grease/Rust: Use a paste of baking soda and water. Apply, let sit, then gently scrub and rinse.
- Bird Droppings: Remove immediately to prevent staining. Soak with cleaner, then gently wipe away.
- Tannin Stains (Leaves/Berries): A mix of oxygen-based bleach (like OxiClean) and warm water can be effective. Always spot-test first.
Common Mistakes to Avoid
- Retracting While Wet: This is the #1 cause of mildew.
- Using Abrasive Tools: Steel wool or hard-bristle brushes damage the fabric’s surface.
- Ignoring the Underside: It collects condensation and grime—clean it too.
- Skipping Rinsing: Soap residue is a dirt magnet.
- Forgetting the Frame: Wipe down metal or aluminum frame parts with a damp cloth to prevent corrosion.
When to Call a Professional
Consider professional awning cleaning services if:
- The awning is very large or high.
