Winter Grill Cover Sizing Guide
Proper fit is crucial for effective winter protection. An ill-fitting cover can be worse than no cover at all. Here’s how to measure correctly:
Measuring Your Grill
- Width: Measure the widest point, including side tables and handles
- Depth: Measure from front to back, including any protruding elements
- Height: Measure to the highest point, typically the lid handle or chimney
- Special features: Note any unique elements like side burners or rotisserie attachments
Size Selection Tips
- When between sizes, always choose the larger option
- Account for thermal expansion in extreme temperature swings
- Consider future accessories you might add
- Check manufacturer sizing charts carefully – they vary between brands
Winter Grill Cover Maintenance
Proper maintenance extends your cover’s lifespan and ensures maximum protection:
Seasonal Preparation
- Pre-winter inspection: Check for tears, worn seams, or damaged closures
- Clean thoroughly: Remove all debris, grease, and stains before winter storage
- Apply protective treatments: Use fabric protector sprays on polyester covers
- Test all closures: Ensure straps, zippers, and buckles function properly
Winter Care
- Remove snow buildup promptly to prevent excessive weight
- Check securing straps after major storms
- Clear ice buildup from drainage areas
- Inspect for wind damage after severe weather
Spring Maintenance
- Remove cover and inspect for winter damage
- Clean thoroughly with mild soap and water
- Allow complete drying before storage
- Store in a cool, dry place away from rodents
- Apply UV protector spray before next season
Common Winter Cover Mistakes to Avoid
- Choosing the wrong size: Too small won’t protect; too large creates wind problems
- Ignoring ventilation: Sealed covers trap moisture and cause rust
- Cheap materials: Budget covers often fail in the first winter
- Poor installation: Loose covers can damage both the cover and grill
- Neglecting maintenance: Small problems become major failures
- Allowing moisture buildup: Even with a quality cover, moisture can accumulate and lead to mold growth. If you discover mold on your grill after winter storage, check out our comprehensive guide on how to clean mold off a BBQ grill for safe and effective removal techniques.
Frequently Asked Questions
Should I cover my grill in winter?
Absolutely. Winter weather is the most damaging to outdoor grills. Snow, ice, and freezing rain can cause rust, corrosion, and permanent damage. A quality cover can extend your grill’s lifespan by 5-10 years and prevent costly repairs.
Can I use my grill cover in snow?
Yes, but remove heavy snow accumulation promptly. Most quality covers can handle normal snowfall, but excessive weight can damage both the cover and grill. Brush off snow regularly and ensure proper drainage.
How do I prevent condensation under my grill cover?
Choose a breathable cover material, ensure proper ventilation, and make sure your grill is completely cool and dry before covering. Avoid plastic covers that trap moisture. Quality covers with fabric backing or built-in vents prevent condensation issues.
What’s the difference between a summer and winter grill cover?
Winter covers use heavier materials that remain flexible in freezing temperatures, have enhanced waterproofing, stronger attachment systems for high winds, and better ventilation to prevent condensation. Summer covers focus more on UV protection and breathability.
How long should a winter grill cover last?
A quality winter grill cover should last 3-5 years with proper care. Premium covers with lifetime warranties can last much longer. Factors affecting lifespan include material quality, climate severity, maintenance, and proper sizing.
