TRAC Ecological Barnacle Buster Concentrate 1 Quart

Barnacle Buster Concentrate is a marine-grade descaler formulated to dissolve barnacle deposits, zebra mussel buildup, calcium, lime scale, rust, and other mineral accumulation from seawater-cooled equipment with minimal dismantling required.

This 1-quart concentrate mixes at a 1:4 ratio (1 part concentrate to 4 parts water), yielding approximately 1.25 gallons of ready-to-use solution. Most standard cooling-system flushes can be completed within approximately 4 hours. For larger jobs requiring more working solution, see the Barnacle Buster Concentrate 1 Gallon.

Parts Desk Insights

The 1-quart size is the right choice for single-system spot treatments and smaller cooling loops ideal for outboard engines, compact heat exchangers, or a single A/C circuit. When you need to flush a full inboard engine cooling system or multiple circuits in one session, the 1-Gallon Concentrate delivers substantially more working solution at a lower cost per gallon of mixed product.
