Awning Maintenance and Annual Cleaning | A BC Owner's Guide
A retractable awning that's cleaned and maintained annually typically outlasts one that isn't by years. This guide walks through the simple seasonal routine that keeps fabric, arms, and motor performing like new in BC's climate.

Why maintenance matters (a lot)
An awning is an outdoor system exposed to UV, moisture, pollution, pollen, and bird activity 365 days a year. Without maintenance, dirt accumulates on the fabric and becomes growing substrate for mildew. Arms and joints slowly accumulate grit. A motor that never gets checked eventually fails in ways it wouldn't have with inspection.
The good news: the maintenance routine is simple and takes about an hour per awning per year for most systems.
Seasonal routine
The pattern that works best in BC's climate:
- Spring (April/May): open the awning, inspect fabric, arms, and hardware; test motor operation; clean accumulated winter debris
- Mid-summer: check that sensors (wind/sun/rain) are clean and functioning; confirm automation is behaving as expected
- Fall (October): deep clean the fabric, lubricate moving joints, winterize per manufacturer instructions
- Winter: keep the awning retracted; if exposed to snow accumulation on top of a box cassette, gently brush off occasionally
How to clean solution-dyed acrylic fabric
For light cleaning (annual or after a dusty day), work through the steps below.
For stubborn stains or mildew on solution-dyed acrylic (Sunbrella-type fabrics), manufacturers typically approve a diluted bleach solution; follow the current manufacturer cleaning guide for exact ratios, as they change occasionally. Rinse thoroughly after. Avoid pressure washing; it can damage the weave.
- Brush off loose dirt with a soft brush
- Hose down with cool water
- Mix mild soap (dish soap works) in cool water
- Apply with a soft brush, gently scrub
- Rinse thoroughly until no soap remains
- Let fabric fully air-dry before retracting; trapping moisture is what starts mildew
Hardware maintenance
The mechanical side of the routine:
- Inspect lateral arm joints and articulations for grit; wipe clean
- Apply a small amount of appropriate lubricant at joints (confirm lubricant type with manufacturer; some recommend against petroleum-based products near fabric)
- Check all mounting hardware for tightness
- Inspect fabric hemlines, seams, and any visible stitching for wear
- Test motor operation at multiple speeds; listen for unusual noise
- Test sensors: if wind sensor paddle is stuck or sun sensor lens is dirty, automation won't work
Winterizing in BC
Coastal BC rarely requires removing an awning for winter; the mild climate and frequent light rain are within the design envelope. Key winter steps:
- Keep the awning retracted when not in active use
- Box cassette awnings: the housing protects the fabric; nothing further needed for most installations
- Open/unhoused awnings: consider a fabric cover or full retraction for extended wet periods
- If your area has significant snow accumulation, do not extend the awning under snow load
- Disable sun-sensor auto-extension if your property gets occasional bright winter sun that could trigger extension when you'd rather the awning stay retracted
When to call for service
Signs you should bring in your installer rather than DIY:
- Motor stutters, hums without moving, or runs unevenly
- Fabric shows tears, loose stitching, or concerning fading
- Arms extend unevenly or crookedly
- Sensor automation behaves erratically
- Water ingress into the cassette housing
- Any unusual noise: bearings, gears, or drive tubes are serviceable but catch issues early
Frequently Asked Questions
How often should I clean my awning fabric?
For most BC residential installations: a thorough cleaning once or twice a year, supplemented by occasional light rinsing after notably dusty periods or pollen-heavy spring. Restaurant and hospitality awnings typically need more frequent cleaning due to cooking-related soil.
Can I pressure-wash my awning?
No, pressure washing can damage the weave of solution-dyed acrylic fabric and force water into the cassette and motor housing. Always use a standard garden hose with a soft brush.
Should I take my awning down for winter?
Not typically in coastal BC. Most awnings are designed to stay installed year-round with the fabric retracted (protected inside the cassette if applicable). Ensure the mechanism is in good condition before winter; if you see issues, address them before weather gets bad.
