Importance of Cleaning and Winterizing

Boating, for many, isn’t just a pastime—it’s a passion. And like any valuable possession, proper maintenance ensures that the passion doesn’t wane due to avoidable damages or performance issues. When it comes to boat care, especially in preparation for storage, two vital steps stand out: cleaning and winterizing.

Understanding Winterization: At its core, winterizing is the process of preparing your boat to withstand the colder months, even in regions with milder winters like Fort Myers. It’s not solely about the cold, but about ensuring that all components of your boat are safeguarded from potential damages that can arise from prolonged periods of inactivity.

Benefits of Cleaning and Winterizing:

  • Protection from Elements: Regular cleaning prevents the accumulation of salt, grime, and other residues that can cause corrosion or damage to the boat’s finish. Winterizing, on the other hand, prevents system failures due to freezing or dormant fuel.
  • Economic Savings: Proactive care reduces the chances of costly repairs or replacements in the future. A clean and well-maintained boat also holds its value better over time.
  • Optimized Performance: Come the new season, a thoroughly cleaned and winterized boat will be ready to deliver optimal performance, ensuring you can set sail without hitches or delays.

By emphasizing the cleaning and winterization processes, you’re not just maintaining a boat—you’re preserving a lifestyle. Elite RV & Boat Storage recognizes this significance, and our goal is to help our Fort Myers community enjoy every boating season to its fullest.

Cleaning Your Boat for Storage

As the old saying goes, “Cleanliness is next to godliness.” This adage rings especially true when it comes to boat maintenance. Ensuring your boat is spick-and-span before storage can significantly extend its lifespan, maintain its aesthetic appeal, and even optimize its performance in the long run.

Exterior Cleaning:

  • Washing: Start by giving your boat a thorough wash using freshwater to remove any salt deposits, especially if you’ve been out in the ocean. Salt is corrosive and can significantly damage the boat’s exterior over time.
  • Waxing: After washing, a quality marine wax should be applied to protect the boat’s finish from UV rays and environmental pollutants. A waxed surface also makes future cleanings easier.
  • Damage Inspection: Check for any signs of damage or barnacles and address them immediately. BoatUS offers a comprehensive guide on tackling common exterior issues that may arise.

Interior Cleaning:

  • Vacuum and Dust: Ensure all interior spaces, including compartments, are free of debris. This prevents mold growth and unpleasant smells.
  • Mildew Check: Due to the humid environment boats often endure, mildew can be a recurrent issue. Using a mildew cleaner or a homemade solution of white vinegar and water can help combat this problem.
  • Dry Thoroughly: Ensure the interior is completely dry. Moist environments can lead to mold growth, which can damage surfaces and degrade air quality.

Engine and Propeller:

  • Basic Clean: Using a mild detergent, clean the engine and surrounding areas to remove oil, grime, and other residues.
  • Propeller Check: Inspect the propeller for signs of wear, dents, or distortion. A damaged propeller can lead to imbalanced and inefficient performance.

Cleaning is not just about aesthetics. It’s about preserving the boat’s functionality and ensuring a hassle-free experience when the boating season resumes. By dedicating time to a meticulous clean-up, you’re laying the foundation for many more memorable voyages.

Winterizing Procedures

Winterizing, while often associated with freezing conditions, is paramount for any boat that’s destined to remain inactive for extended periods. Even in milder climates like Fort Myers, FL, winterizing ensures that your boat’s systems remain in optimal condition, ready to roar back to life when the season beckons.

Draining Water Systems:

  • Why It’s Essential: Any water left in the boat can lead to corrosion or provide a breeding ground for harmful bacteria.
  • Procedure: Ensure that you drain all water systems, including the engine, freshwater system, and bilge. It prevents any water damage and preempts the risk of freezing in colder conditions.

Fuel System Care:

  • Stabilize: Over time, unused fuel can degrade, leading to the formation of harmful deposits. Adding a fuel stabilizer prevents this degradation.
  • Run the Engine: Once the stabilizer is added, run the engine for about 10 minutes. This circulates the stabilized fuel through the engine, ensuring that every part is protected.
  • Top Off the Tank: Fill the fuel tank to prevent moisture accumulation, which can lead to internal rust.

Battery Maintenance:

  • Charging: Before storage, ensure that the battery is fully charged. A depleted battery can freeze or suffer irreversible damage.
  • Disconnection: Disconnect the battery to prevent any slow discharge.
  • Storage: Store the battery in a cool, dry place. Regularly check and recharge as necessary throughout the storage period.

Antifreeze Application:

  • Why It Matters: Antifreeze prevents water in the boat’s systems from freezing and cracking the system’s components.
  • Application: Use non-toxic antifreeze in the boat’s water systems. The Discover Boating website offers an in-depth guide on the correct application procedures and the types of antifreeze to use.

Winterizing might seem like a meticulous task, but its benefits are manifold. By taking these steps, you’re not just preparing for the winter—you’re gearing up for a hassle-free, enjoyable boating experience come the next season.

Final Checks Before Storage

With cleaning and winterizing out of the way, there’s a final checklist to run through before your boat is ready for its hibernation. These last-minute checks ensure that no stone is left unturned, setting you up for a smooth transition when it’s time to bring your boat back into action.

Covering the Boat:

  • Why It Matters: A proper cover protects your boat from dust, debris, moisture, and UV rays, all of which can cause wear and tear over time.
  • Types of Covers: While tarpaulins can be a quick fix, a fitted boat cover or shrink-wrapping provides comprehensive protection. Ensure proper ventilation to prevent mold and mildew formation.

Documentation and Items Check:

  • Essential Documents: Make sure all essential documents like registration, insurance, and user manuals are safely stored. It’s a good idea to keep a digital backup.
  • Personal Items: Remove any personal items or valuables from the boat. Over time, items like electronics or life vests can get damaged if left on the boat, especially in humid conditions.


  • Importance: Proper ventilation prevents the growth of mold and mildew, which can be damaging and present health risks.
  • Tips: Open some hatches or invest in vented boat covers. For those storing indoors, ensure the storage area itself is well-ventilated.

Quick Inspection:

  • Last Look: Before saying goodbye, take one final walk around and inside your boat. Look for any signs of damage or things you might have missed. Check all seals, hatches, and covers to ensure they’re secured.

Your boat is now prepared for its rest, shielded against the challenges of time and environment. When the skies beckon again, with these measures in place, you’ll find your vessel ready to sail smoothly, just as you left it.
