STAR BRITE Salt Off Concentrate 128 OZ

Best for: boat owners with large salt exposure and need a robust cleaning and engine flush option. The formula removes salt deposits from multiple surfaces, including fiberglass, vinyl, painted surfaces, metal, plastic, wood, and glass. It also functions as an engine flush to improve cooling system performance and service life. The protective polymer layer helps resist future salt buildup, extending equipment life. Limitation: as a highly concentrated product, follow dilution guidance to avoid over-application on delicate surfaces.
STAR BRITE Salt Off Kit with Applicator 32 OZ

This complete kit includes an applicator for easy use, ideal for applying Salt Off Concentrate via a garden hose. It’s best for boat owners who want a ready-to-use flushing and cleaning solution in one package. The kit’s design supports quick treats for engines and salt build-up on hulls or gear. Caution: ensure correct hose pressure and rinse thoroughly after use to prevent residue on surfaces.
Salt-Away Concentrate Gallon

Best for: users who prefer a biodegradable, water-based formula with corrosion inhibitors. Salt-Away Concentrate is designed to remove salt from all surfaces, including engines, boats, jetskis, and vehicles. It’s non-hazardous and leaves behind protective inhibitors. Bees caution: do not rinse with fresh water after application, as the product’s corrosion inhibitors are intended to stay on surfaces. It’s versatile for inboard and outboard flushing as well as general salt removal.
Escentile [1 Gallon] Concentrated Salt Remover

Best for: boat owners seeking high-efficiency salt removal with an economical gallon size. This concentrate claims double the active ingredients of many competitors and forms a protective shield that bonds to surfaces to deter future salt buildup. It’s suitable for boats, engines, and trailers. Limitation: effectiveness depends on proper dilution and contact time. Use with hose applicator or engine flush kit for best results.
Durabasics 1 Gallon Salt Remover Concentrate

Best for: versatile use around boats, motors, and vehicles exposed to salt. The concentrate is designed for easy mixing with a garden hose or engine flush kit (sold separately) and works well for washing salt deposits away from hulls and engines. It’s advantageous for routine maintenance, though users should confirm dilution rates to achieve the desired surface treatment without oversoaking sensitive finishes.
