Spring has finally arrived in Minnesota. The ice is melting, the lakes are calling, and you are likely eager to get your boat back on the water. But before you launch, you have one important task left: dealing with your winter boat cover. Uncovering your vessel is an exciting milestone, but how you treat your cover now determines how well it protects your boat when the cold returns.

Before putting your boat cover away for the season, it's important to consider how your actions impact both its longevity and your wallet. Smoothly transitioning into a sustainable mindset, let's look at why reusable marine canvas covers are a better choice than plastic alternatives.

The Sustainable Choice: Ditching the Plastic Wrap

When it comes to winterizing boats, many owners still rely on disposable plastic shrink wrap. While this method offers temporary protection, it creates a massive environmental problem. Every spring, boatyards fill dumpsters with single-use plastic wrap that takes centuries to decompose in landfills.

A reusable, custom-fit marine fabric cover from Canvasworks is a more eco-friendly alternative. By choosing a high-quality cover, you avoid mountains of plastic waste and eliminate yearly shrink-wrap costs. A durable marine canvas cover pays for itself over time while keeping our lakes and lands cleaner.

General Cleaning & Care for Marine Fabric

After months of enduring Minnesota snow, wind, and dirt, your boat cover needs a good wash. Regular cleaning prevents dirt from embedding deep into the fabric fibers, which can cause premature wear.

Follow these simple steps for general cleaning (they’re very similar to the care and maintenance steps for all our boat covers):

  1. Brush it off: Lay the cover flat on a clean driveway or lawn. Use a soft-bristle brush to sweep away loose dirt, leaves, and debris.

  2. Prepare a mild soap solution: Mix 1/4 cup mild dish soap (like Dawn) or a specialized marine canvas cleaner with 1 gallon of lukewarm water.

  3. Wash gently: Use a soft brush or sponge to work the soapy water into the fabric. Avoid using stiff brushes or pressure washers, as these can strip the water-repellent coating and damage the seams.

  4. Rinse thoroughly: Use a garden hose to rinse the cover completely. Ensure no soap residue remains, as leftover soap can attract new dirt and compromise water repellency.

Tackling Tough Stains on Your Cover

Sometimes, general cleaning is not enough. Winter storage can leave your cover battling stubborn stains from bird droppings, tree sap, or lingering moisture. Here is how to handle the tough spots safely.

Bird Droppings & Tree Sap

Bird droppings are highly acidic and can eat away at the fabric if left untreated. Tree sap can harden and become incredibly difficult to remove. For these stains, apply a targeted marine canvas cleaner directly to the spot. Let it soak for 10 to 15 minutes to soften the residue. Gently scrub the area with a soft brush, then rinse heavily with clean water.

Mold & Mildew

Marine canvas is naturally resistant to mold and mildew, but those can still develop — especially on dirt or organic matter clinging to the cover. In most cases, scrubbing alone won’t remove mold or mildew; a soak is needed for best results. Be careful when using bleach to remove mold & mildew, as it can quickly degrade stitching. It is better to spot soak areas with a diluted bleach solution than to soak the entire cover.

Proper Storage & Precautions

Once your cover is clean, proper storage is critical. The most common mistake boat owners make is storing a cover before it is completely dry.

The Importance of Drying

Never fold or store a damp boat cover. Even a small amount of trapped moisture will breed mold and mildew over the summer, ruining the fabric and leaving you with a foul smell in the fall. Hang the cover over a sturdy clothesline, a fence, or even over your boat on a sunny, breezy day. Allow it to air dry completely.

Folding & Storing

Once bone dry, fold the cover neatly to prevent deep creases. Store it in a breathable canvas storage bag. Avoid putting your cover in a sealed plastic bag or an airtight container, as changing temperatures can cause condensation to form inside.

Keep the storage bag in a cool, dry place, such as a garage shelf or a dry basement. To protect your cover from mice and other rodents seeking nesting materials, hang it from the rafters rather than directly on the floor. Otherwise, you can store it in a metal garbage bin with a tightly fitting lid. You can also place cedar blocks nearby to deter pests naturally.
