What To Look For: Best Salt Remover For Marine Boats

When shopping for a salt terminator for our boat, we will want to consider several criteria. The most important factor is that it effectively removes salts from surfaces like fiberglass and metal without damaging them.

It should also be easy to apply and remove to get back onto the water quickly. Let’s review each of these factors in more detail.

Application Method

The application method is the first factor most buyers should consider. It typically indicates how long the process takes and how effective the product is when removing salt and providing future boat protection.

This wash gives a deeper clean and removes heavy-duty salt stains. It is typically sold as liquid soap or bottle spray. The spray application is fast and easy but won’t work as well.


The most effective salt removers contain strong alkaline cleaners like sodium hydroxide or potassium hydroxide to break down tough deposits on boats. These products work better than traditional household cleaners and are specially formulated for marine use.

They should also include corrosion inhibitors to protect surfaces from further damage due to oxidation or rusting. The key is to find something safe to use that won’t strip the boat’s paint, polish, or wax.


Price point factors heavily into the decision when purchasing a boat cleaner. Look at different brands' price offerings as well as sizes available.

However, most options range between $20-$50. Typically, the spray bottle solutions will be the cheapest because they provide the weakest coating. More expensive options add a PTEF coating for better boat protection.

Is Salt Remover Safe To Use On Boats?

It’s important to note that some salt removers contain harsh chemicals that can damage paint and surfaces on your boat if not used with caution. This means we should always read all labels carefully before using any cleaning product or chemical on our boat.

However, when used properly, most salt removers are usually safe for removing unwanted deposits from boats without causing any damage. It’s safe but best to avoid excessive exposure.

Most products also indicate they are non-hazardous and safe to use on all metals. This means they are safe for the person using the salt remover and the boat itself.

Does Salt Remover Also Work On Marine Engines?

The short answer to this question is yes. It can be effective for removing salt from boat engines. This product does not just remove the visible white residue from surfaces. It also helps to reduce corrosion by neutralizing acids left behind.

These products are engine friendly. Be sure to check the product details first, but all options listed above will work on outboard and inboard engines. This is a recommended maintenance step for any boats with excessive salt exposure.

This is known as motor or engine flushing. It’s a common step when winterizing a boat and a highly effective way to keep a boat free of rust and corrosion while protecting it for the long term. It can also be used to clean and protect the boat’s cooling system.

How To Apply Salt Remover On A Boat

Salt is one of the toughest elements to remove from a boat. For those owners living in coastal regions, salt deposits on the hull and parts can cause major damage that requires expensive repairs over time.

In order to prevent this problem, it’s important to regularly give your boat a proper cleaning with salt remover. Here’s how anybody can apply salt remover on a boat easily.

Use A Hose Attachment

This is probably the easiest way of applying salt remover. Simply attach an adjustable garden hose spray nozzle to the solution bottle before spraying it over surface areas. Many of the best options will even include a hose attachment.

This will spread the solution across the hull fast. Be sure to cover all areas. Depending on the strength of the hose, a simple scrub or wash is also required.

Spray Bottle Option

Another option is to buy a simple spray solution This product can spray directly on the boat’s surface with no scrubbing or application needed. But these tend to be the least reliable products.

They also aren't ideal to use for an outboard engine flush. If the objective is to clean and prepare the engine for the upcoming season, other options will provide longer-lasting results.

Mix-In With Traditional Cleaner Method

Another option is to buy a salt remover wash. These products will mix with traditional soap to provide a high-strength cleaning that better targets salt deposits, salt residue, and other stains.

This solution would be added to the soap and water and scrubbed on the surface. The solution works like a convenient mixing unit. This is a smart way to remove salt and do a good boat cleaning all at once.

How Often Do You Need To Use A Salt Remover For Boats?

One of the most important aspects of regularly maintaining a boat is using salt remover. It helps protect and preserve the boat's paint, metal parts, and other surfaces. It can even prevent damage caused by saltwater exposure to the engine. But how often should it be done?

Ultimately, it depends on the boat's frequency and weather conditions. Ideally, it would be best to do it after every boating trip in saltwater conditions. But this is not always possible.

Instead, aim to use it once or twice per month, assuming you use the boat at least once weekly. It can be done even less frequently if we are only boating in freshwater lakes because the salt buildup is less common.
