Outdoor Cover Care Handbook: Extend the Life of Every Cover
TL;DR: Clean quarterly, dry before storing, never machine-wash PVC, treat mold immediately, and match storage to climate — a maintained cover lasts 2x longer across car, boat, grill, and outdoor furniture covers.
Why Covers Need Care Too
Covers sit outside 365 days — sun, rain, snow, salt, bird droppings. Without maintenance, even the best fabric degrades 2x faster. This handbook covers care for all cover types: car, boat, motorcycle, grill, furniture, and more.
Universal Care Schedule

Every Quarter (20 min)
| Task | How |
|---|---|
| Rinse & spot clean | Hose + mild soap for stains |

Cleaning by Material
Oxford / Polyester Covers (most common)
- ✅ Mild soap + soft brush + hose

Non-Woven / Fleece Covers (indoor)
- ✅ Vacuum or shake
- ✅ Spot clean with damp cloth
- ❌ No machine wash (material breaks down)
Mold & Mildew: The #1 Killer
Mold weakens fabric fibers and stains permanently. Prevention beats treatment:
Prevent:
- Always dry cover completely before storing
- Use vented covers for long-term outdoor
- Don't cover a wet car/boat/grill
Treat (early):
- Brush off dry mold
- Mix 1 part white vinegar + 3 parts water
- Apply, wait 10 min, scrub gently
- Rinse, dry in shade completely
Seasonal Checklist
Spring
- Deep clean after winter
- Inspect for winter damage
- Refresh waterproofing
Summer
- Watch UV exposure (harshest season)
- Brush debris after storms
- Check straps weekly if windy
Fall
- Deep clean before winter storage
- Dry completely before covering long-term
- Add support poles for snow areas
Winter
- Clear snow accumulation regularly
- Check weekly for ice damage
- Never pull frozen covers off (wait to thaw)
When to Replace
| Sign | Action |
|---|---|
| Fabric cracks/peels | Replace — integrity gone |
| Coating washes off | Replace (or heavy re-treatment) |
| Seams separating | Repair or replace |
| Mold beyond cleaning | Replace — fibers weakened |
| Cover age 5-7 years | Evaluate replacement |
FAQ
Q: Can I machine wash any cover? A: Only Oxford/fabric covers labeled machine-washable (cold, gentle). Never machine-wash PVC, vinyl, or non-woven — they degrade in the machine.
Q: How do I remove bird droppings? A: Soften with water, then gentle scrub with mild soap. Don't scrape dry — it scratches the coating.
Q: Do covers need waterproofing treatment? A: Quality covers are pre-coated (PU/laminated). Re-apply treatment annually if water stops beading.
Q: Should I store covers inside in winter? A: Only indoor covers (non-woven, fleece). Outdoor covers are built for winter — store them on the vehicle with proper support.
Q: Do you sell replacement parts (straps, grommets)? A: For OEM customers, yes — replacement hardware available. Contact us for bulk parts.
