Salt-Away Salt Remover for Boats, Engines & Marine Equipment
Salt-Away is a marine salt remover and corrosion-control solution designed for boaters, anglers, marina operators, and marine maintenance crews who need to remove salt buildup from engines, hulls, trailers, hardware, and exterior surfaces. Fisheries Supply carries Salt-Away sprays, concentrates, applicator kits, and engine-flush options for routine saltwater washdowns and long-term corrosion prevention.
What Is Salt-Away?
Salt-Away is a water-based marine cleaning solution formulated to dissolve salt deposits, break down sodium crystals, and loosen corrosion-forming residue on marine equipment. It is used after saltwater exposure to help protect boats, engines, trailers, fishing equipment, dock hardware, and onboard systems from salt accumulation.
Because the formula is non-hazardous and biodegradable, Salt-Away can be used on a wide range of common marine materials, including painted surfaces, metal, plastic, gelcoat, vinyl, rubber components, and engine cooling passages.
Salt-Away Benefits for Marine Maintenance
Saltwater is one of the most aggressive sources of corrosion in boating. A consistent Salt-Away rinse helps reduce salt deposits before they harm surfaces or remain trapped inside cooling passages and metal components. When allowed to air-dry on internal passages or engine blocks, it leaves a micro-thin, non-residual protective barrier that inhibits atmospheric rust and oxidation without stripping boat wax or ceramic coatings.
- Removes crystallized salt: Helps dissolve visible and hidden salt deposits from exterior marine surfaces.
- Supports corrosion prevention: Leaves a temporary protective film on surfaces that reduces salt residue contributing to rust, oxidation, staining, and premature wear.
- Protects engine cooling passages: Helps clear salt buildup from outboard, inboard, stern drive, I/O, and personal watercraft cooling systems when flushed through the cooling jackets.
- Works on common marine materials: Suitable for painted surfaces, metals, plastics, gelcoat, vinyl, and rubber when used as directed.
- Fits routine washdown workflows: Useful after saltwater trips, trailering, docking, fishing, or seasonal maintenance.
Salt Removal Product Selection Guide

| Salt-Away Engine Flush | Flushing salt from engine cooling passages | Outboard engines, inboard engines, stern drives, I/O systems, and personal watercraft | Helps dissolve salt residue inside cooling systems before buildup accelerates corrosion |
| Salt-Away Concentrate Kit | Routine full-boat washdowns and larger maintenance jobs | Hulls, decks, hardware, trailers, exterior machinery, painted surfaces, and marine components | Efficient dilution for frequent saltwater cleaning and corrosion-prevention routines |
| Salt Off & Applicator | Alternative or supplemental marine salt-removal workflow | Hull washdowns, deck hardware, trailering equipment, and salt-exposed exterior surfaces | Additional product flexibility for complete salt-control maintenance |
How to Use Salt-Away on Boats and Engines
- Rinse loose debris first: Remove abrasive sand, grime, and heavy surface mud with fresh water before applying the salt-removal solution to protect gelcoat and paint from scratching.
- Apply Salt-Away to the target area: Use a spray bottle, concentrate mixer, or inline engine applicator depending on whether you are treating exterior gear or running an engine flush.
- Allow the solution to build foam and dissolve deposits: Run or spray the solution until it begins to exit or coat the target area, giving the formula time to break down sodium crystals.
- Flush engines wet; lightly rinse exterior surfaces: For engine cooling systems, turn off the engine and water supply while the diluted Salt-Away solution is still present to trap it inside the cooling jackets. For hulls, trailers, marine glass, and deck hardware, follow application with a light, fresh-water rinse (using the water-only setting on your mixing unit) before drying to prevent surface spotting or streaking. The active corrosion-inhibiting barrier bonds immediately and will remain on the substrate.
- Repeat after every saltwater exposure: Integrate this step into your standard post-trip maintenance routine after boating, fishing, trailering, or operating in marine environments.
Frequently Asked Questions
What is Salt-Away used for on a boat?
Salt-Away is used to dissolve salt deposits and reduce corrosion risk on boats, marine engines, trailers, fishing gear, deck fittings, and metal hardware. Boaters apply Salt-Away after saltwater exposure to help clear crystallized sodium residue from exterior surfaces and protect cooling passages, gelcoat, stainless steel, aluminum, vinyl, and rubber components.
Can I use Salt-Away to flush an outboard engine?
Yes, Salt-Away can be used to flush salt buildup from outboard engines, inboard engines, stern drives, I/O systems, and personal watercraft cooling passages. Use Salt-Away concentrate with an engine-flush mixer or applicator, follow the engine manufacturer’s flushing procedure, and leave the final diluted Salt-Away mixture inside without a fresh-water rinse.
Do you rinse Salt-Away off after applying it?
For engine flushing, the diluted solution is left inside the cooling system to protect internal corridors. However, for exterior surfaces like hulls, trailers, marine glass, and deck hardware, you should lightly rinse the treated areas with fresh water after application to prevent soap spots or streaking. The active corrosion-inhibiting barrier bonds immediately to the substrate and will not wash away with a light rinse.
Is Salt-Away safe on gelcoat, paint, metal, vinyl, and rubber?
Yes, Salt-Away is a water-based, non-hazardous, biodegradable salt remover made without petroleum solvents or harsh acids. When used as directed, Salt-Away is suitable for marine gelcoat, painted surfaces, stainless steel, aluminum, plastics, vinyl, rubber, acrylics, deck equipment, trailer parts, and other salt-exposed boat components.
How often should I use Salt-Away after boating in saltwater?
Salt-Away should be used after every saltwater outing for the strongest corrosion-control routine. Regular use helps remove hidden salt crystals from hulls, trailers, railings, fishing equipment, raw-water cooling passages, and metal hardware before salt residue contributes to rust, oxidation, staining, scale buildup, or premature wear.
Which Salt-Away product should I choose for boat maintenance?
Choose Salt-Away spray for quick surface treatment, Salt-Away concentrate kits for full-boat washdowns, and Salt-Away engine-flush mixers for cooling system maintenance. Sprays fit deck fittings, railings, trailers, and fishing gear, while concentrates and hose mixing units work better for hulls, machinery, larger surfaces, and frequent saltwater cleaning.
