How to Treat Rust on Boats and Ships

Unfortunately, rust is something that every boat or ship-owner has to deal with at some point but it doesn’t mean you have to accept it. Like with any prized possession, you definitely want to do everything in your power to protect your boat or ship’s longevity. This includes protecting it from rust corrosion and treating it when it inevitably occurs.

Treating Rust on Boats and Ships with Neutrarust

As the adage says, “prevention is better than cure”, and this is especially true of rust. Rust has even been described as “boat cancer”. Luckily for you and your boat or ship, it doesn’t have to be terminal.

With a few preventative measures and some great treatment options available, your boat or ship will be rust-free and protected against corrosion in no time!

Preventative Care

An important thing to consider is the type of water that your boat or ship is predominantly in or exposed to. This is because it may influence which preventative measures you need to use. Saltwater speeds up the corrosion of metals due to its electrolytic nature. Freshwater has far less salt and so rust is less likely to develop as fast.

One important preventative measure is to do regular checks for rust. If you find small areas beginning to rust, it is usually far easier to treat before it progresses. In some cases, you can remove the piece that has rusted and replace it. Alternatively, you can use a rust treatment. We’ll look at a very good rust treatment option in the next section.

Lastly, you can use a preventative that will protect your boat or ship against rust. Quality wax preventatives like the Neutrarust Wax Rust Preventative can provide protection from rust between 2 and 5 years as a minimum. Our wax’s resistance to water and cost-effectiveness make it an excellent choice for exterior and interior use.

How to Neutralise Corrosion Using the Neutrarust 661® Rust Converter Treatment

Fortunately, Neutrarust’s global reputation to solve rust and corrosion problems within the marine industry is second to none. While it’s important to work on preventing rust, unfortunately, it is possible that you will still have to deal with your fair share of it. Luckily, Neutrarust developed the ideal solution. Two to three coats of the Neutrarust 661® Rust Converter simply need to be painted onto a washed, rusted surface.

Once applied, the solution converts the rust and forms a hard ready to paint, impermeable layer over the metal. This prevents water and oxygen from reacting with the metal underneath and causing further corrosion. Not only this, but the solution actually forms a chemical bond with the metal to neutralise the rust and leaves a primer finish.

Then, you can paint over it with a paint colour of your choice and give your boat or ship a fresh look.


Rust is an inevitable problem for any boat or ship-owner. Prevention is always better than cure and so it’s important that you know how to care for your assets. However, sometimes prevention can only do so much. Luckily, Neutrarust 661 can help to treat rust and also prevent further corrosion.
