Barnacle Buster Concentrate is a professional-grade marine descaler formulated to dissolve barnacle and zebra mussel deposits, calcium, lime scale, rust, and mineral buildup from seawater-cooled equipment — with minimal dismantling required.
One gallon of concentrate mixes at a 1:4 ratio (1 part concentrate to 4 parts water), producing approximately 5 gallons of ready-to-use solution — making it the economical choice for larger cooling-system flushes.

Directions for Use
Dilute concentrate before use — do not apply full strength. Circulate diluted solution through the system and allow adequate dwell time (typically up to 4 hours). Rinse thoroughly with fresh water after treatment. Remove zinc anodes before treatment. Use additional caution with aluminum, copper alloys, and systems containing dissimilar metals.
Parts Desk Insights
Best use case: The concentrated gallon is the economical choice for larger cooling-system flushes. One gallon of concentrate yields five gallons of working solution — substantially more usable descaler than a premixed one-gallon container. Ideal for seasonal raw-water cooling system maintenance, heat exchanger service, and pre-lay-up engine flushes on inboard and sterndrive engines. Particularly effective when scale buildup is reducing cooling efficiency.
