Should You DIY Barnacle Removal? When to Do It Yourself and When to Call the Pros

Barnacles are one of the biggest headaches for boat owners, latching onto hulls, propellers, and even water intake systems. If you’ve noticed barnacle buildup on your boat, you might be wondering: Should I remove them myself, or should I hire a professional?

While DIY barnacle removal can save money, it’s not always the best option—especially if the infestation is severe or your boat has delicate coatings. In this post, we’ll break down when DIY barnacle removal is a smart choice and when it’s better to call in the experts.

DIY Barnacle Removal: What You Need to Know

If your boat has a light barnacle buildup, you can often handle the cleaning yourself with the right tools and precautions.

Tools for DIY Barnacle Removal:

• Plastic or metal scraper – to dislodge barnacles without damaging hull coatings

• Soft-bristled brush or sponge – for cleaning leftover residue

• Power washer – for stubborn growth (if your hull can handle it)

• Gloves and protective eyewear – to avoid cuts from sharp barnacle shells

• Eco-friendly hull cleaner – to remove biofouling without harming marine life

Best Practices for DIY Removal:

• Work slowly and carefully to avoid damaging antifouling coatings.

• Remove barnacles as soon as you notice them—the longer they sit, the harder they are to remove.

• If cleaning your boat in the water, check local regulations—some areas prohibit underwater scraping due to environmental concerns.

When DIY Removal Might Not Be Enough

DIY barnacle removal works well for minor cases, but it isn’t ideal in the following situations:

• Heavy barnacle infestations – If your boat is covered in thick layers, manual scraping will take hours (or even days).

• Hull damage or peeling coatings – Scraping off barnacles can worsen the problem if your protective coating is already compromised.

• Clogged propellers or engine intakes – Barnacle growth in these areas can reduce engine efficiency and lead to overheating.

When to Call the Pros

Sometimes, professional cleaning is the safest and most efficient option. A trained marine service provider can:

• Remove barnacles quickly and safely using specialized tools.

• Reapply antifouling coatings if barnacle growth has stripped them away.

• Inspect for hidden damage caused by biofouling.

• Clean hard-to-reach areas, like propellers, rudders, and cooling systems, without causing harm.

If your boat hasn’t been cleaned in a long time or you notice performance issues like sluggish speed or higher fuel consumption, a professional cleaning might be the best investment.

Preventing Barnacle Growth: The Best Long-Term Strategy

The easiest way to avoid costly and time-consuming barnacle removal is to prevent growth before it starts. Here’s how:

1. Use a High-Quality Antifouling Coating

Eco-friendly antifouling solutions, like Barnacide’s advanced coatings, create a protective surface that prevents barnacles from attaching in the first place—without harming marine ecosystems.

2. Clean Your Hull Regularly

Frequent cleaning prevents barnacle buildup from reaching a critical level. A quick clean every few weeks is far easier than dealing with a full infestation.

3. Keep Your Boat Moving

Barnacles attach more easily to stationary boats. If possible, take your boat out frequently to discourage biofouling.

The Bottom Line

DIY barnacle removal is a great option for minor fouling, but for heavy infestations, hull damage, or hard-to-reach areas, professional cleaning is often the better choice. The best strategy? Prevent barnacle growth altogether with an effective antifouling solution.
