About the products in this kit
5L Exterior Salt Wash Detergent
This high-performance detergent is built to break down salt deposits and mineral buildup before they cause long-term corrosion. Infused with anti-rust inhibitors and a powerful degreasing formula, it’s tough on grime but safe on paintwork, plastics, glass, gel coat, and metals.
Use it through The Captain’s Musket or your foam cannon to get a thick, even lather that clings and cuts through the muck. It is ideal for boats, jetskis, trailers, 4WDs, RVs, and any gear exposed to salt or the elements.
Dilution: 100ml per wash (1:10 ratio)—a single drum can provide up to 50 washes.
5L Engine Flush Solution
Salt doesn’t just sit on the surface — it gets inside your cooling system where you can’t see it. That’s where this solution comes in. Designed to flow through your outboard, jet ski, or PWC cooling system, it breaks down internal salt build-up and leaves behind a protective barrier to reduce corrosion.
Use it with a flush port adapter or run it through The Captain’s Musket with the flush setting for quick, no-fuss maintenance.
Perfect for both saltwater and brackish conditions, this is your engine's best mate after every mission.
FAQ
Q: What’s the pH level of the Salt Wash Detergent?
A: The Salt Wash Detergent is pH neutral (~7), making it safe for frequent use on a wide range of materials without causing degradation. It’s effective at removing salt residue and grime while being gentle on paint, gelcoat, rubber, metals, and plastics.
Q: Will the Engine Flush affect rubber seals or gaskets in my outboard/PWC?
A: No — the Engine Flush Solution is formulated to be non-aggressive and is safe on rubber seals, O-rings, gaskets, and internal cooling components. It won’t dry out or degrade sensitive parts.
Q: How long should the Engine Flush be run for?
A: We recommend running the flush for 2–3 minutes through your outboard or PWC cooling system. This allows enough time to dissolve salt build-up and circulate corrosion inhibitors throughout the internal pathways. Always follow with a clean water rinse.
Q: Does the Salt Wash leave any residue?
A: No. The Salt Wash is designed to rinse clean, leaving behind no sticky or soapy residue. It does, however, leave a light protective film that helps inhibit corrosion and slow down salt crystallisation between washes.
Q: Is it safe on aluminium, stainless, and coated surfaces?
A: Yes — being pH neutral, it’s 100% safe on polished and anodised aluminium, stainless steel, powder-coated parts, and painted surfaces. It’s perfect for boats, trailers, bullbars, and other marine or 4WD components.
Q: How many washes can I get from the 5L Salt Wash?
A: Each wash typically uses about 70ml of product, which means you can get up to 70 washes from the 5L bottle. Usage may vary depending on how heavy the salt build-up is and your foam gun settings.
Q: Is the Engine Flush suitable for all engine brands?
A: Yes. The solution is compatible with all major outboard and PWC brands including Yamaha, Mercury, Honda, Suzuki, Sea-Doo, and more – as long as they use a raw water cooling system with a standard flush port or earmuff adapter.

After spending a week by the beach, my car was covered in salt spray. Following the user instructions, I applied the detergent using the Salty Gun and found it to be a brilliant product. It washed off all the salt crystals and after using it as well as the other products my car shone like it was brand new.

Living in northwest Ohio can take a toll on vehicles, especially personal vehicles that you do your best to take care of while still working with it. I snow plow with my personal vehicle so it gets very dirty and very salty. After the first wash I was highly impressed. I put Salty Captain soap in a foam cannon on a pressure washer and soaked my truck and let it sit accordingly. The soap foamed very well and provided a great coat on my truck. I feel as though it got rid of the salt and road grime very well. I’m excited to use it further and hope it makes the truck I take a lot of pride in last longer!
