How to Maintain and Clean a Floating Plastic Dock

Installing a floating dock is a great investment that lets you fully enjoy your waterfront property, whether it’s at the cottage, in a marina, or at a fishing lodge. But one question always comes up: how do you maintain and clean a floating plastic dock?

If you’ve chosen a Candock dock, the answer is simple: you can almost forget about maintenance. Thanks to its innovative design, ultra-resistant materials, and proven durability, Candock offers a truly maintenance-free dock system. Below, we’ll cover everything you need to know to keep your dock safe, clean, and long-lasting.

Do Plastic Floating Docks Require Maintenance?

The short answer: no structural maintenance is required with Candock.

Unlike wooden docks that need sanding, staining, or repainting, or aluminum docks that can oxidize or require welding, Candock’s HDPE (high-density polyethylene) cubes are UV-resistant and designed for zero upkeep.

Your dock doesn’t need to be painted, sealed, or repaired regularly. This means you spend less time maintaining and more time enjoying your waterfront.

Occasional Accessory Checkups

While the dock cubes themselves require no maintenance, the bolted accessories—like cleats, ladders, or benches—deserve a quick seasonal check. Here’s what you should do:

  • Check solidity once per season.
  • Tighten bolts if needed, especially after storms or heavy use.
  • Replace damaged parts to ensure comfort and safety.

This inspection takes just a few minutes but helps keep your dock safe and reliable.

Preventing the Dock from Touching the Bottom

Candock cubes are designed to float thanks to the air inside them. However, it’s important to make sure they never rest on the lake or riverbed.

Why? Because prolonged contact and regular friction with rocks, branches, or abrasive bottoms could damage the cubes or reduce their performance.

Pro tip: Place your dock in a sufficiently deep area or adjust its layout to ensure it stays afloat even during seasonal water level changes. 

How to Clean a Floating Dock

Even though Candock cubes don’t rot, warp, or absorb moisture, a seasonal cleaning is recommended.

Once a season, take a few minutes to:

  • Spray the dock with fresh water using a hose or a pressure washer on low.
  • Remove algae, sediment, and debris that may accumulate on the surface.
  • Clean corners and accessories to maintain a clean and safe dock.

This light cleaning keeps your dock looking great and prevents buildup over time.

Winter Storage: A Few Simple Precautions

This is one of the most common questions we get. The answer is: it depends on your conditions.

  • In regions with harsh winters and ice movement, it’s best to remove the dock and store it on a flat outdoor surface.
  • In areas where there is no ice movement, you can leave your Candock in place all winter long.

Leaving it in the water can save you time and reduce costs related to winter storage and spring reinstallation.

One of the greatest advantages of Candock is modularity: the cubes disassemble quickly, move easily, and store compactly if removal is necessary.

Safety: Maintenance Equals Peace of Mind

Maintaining your Candock dock isn’t only about aesthetics—it’s mostly about safety. Best practices include:

  • Inspecting cube connections to ensure they’re securely locked.
  • Checking accessories regularly so they remain reliable and safe.

These simple actions guarantee structural integrity and prevent accidents.

Key Benefits of Choosing a Candock Floating Dock

To summarize, if you’re looking for a dock that combines durability, simplicity, and peace of mind, Candock is your best choice:

  • No structural maintenance required thanks to UV-resistant HDPE cubes.
  • Quick seasonal cleaning keeps the dock in top shape.
  • Light accessory checkups maintain user safety.
  • Easy winter storage (or the option to leave it in the water, depending on conditions).

With Candock, dock maintenance comes down to just a few quick checks—leaving you more time to enjoy your waterfront.

Conclusion: More Time on the Water, Less Time on Maintenance

With a Candock floating dock, you can stop worrying about maintenance and focus on what really matters: relaxing, entertaining, and making memories on the water. Whether you’re a homeowner, a marina operator, or a lodge manager, you’ll enjoy a product that is durable, reliable, and virtually maintenance-free.
