Frequently Asked Questions
Should I remove my shade sail for winter?
In most climates, removing the sail is the safest option. Taking it down, cleaning, fully drying and storing it reduces UV fading, mildew and tear risk from winter storms and ice. If you must leave it up, tension it properly, clear debris after storms and use anchor covers to protect hardware.
How should I store a shade sail to prevent mildew?
Clean the sail with mild soap and water, rinse, and let it dry completely in sun before folding or rolling. Store in a breathable bag or container in a cool, dry place—avoid airtight plastic that traps moisture. Check the sail mid-winter if stored in damp basements or garages.
How do I winterize anchors and hardware?
Loosen tension slightly to reduce constant load, or remove turnbuckles and other exposed metal and store them indoors. If you leave hardware in place, cover stainless or coated metal with weather sleeves and apply a light corrosion inhibitor. Replace any rusted or bent fittings before reinstalling in spring.
