Why you'll want it

• Meant for seals, gaskets and hoses. Its formula is meant for hoses, impellers, seals and gaskets, so you can clean without worrying about those parts.
• One gallon makes several gallons of cleaner. Mix it 1 part to 4 parts fresh water. One gallon can make several gallons of cleaner.
• Clean the cooling system before winter storage. Haul-out season is a good time to clean the cooling system before winter storage. It is intended for regular maintenance.

What it is

Star brite Marine Descaling Fluid Concentrate is a 1-gallon descaling product made by Star brite. It is made for raw water-cooled systems, including outboard and inboard motors. It suits the cooling jackets and tubes, the heat exchangers, plus AC systems.

How to use it

1. Mix one part concentrate with four parts fresh water, a 1:4 ratio.
2. Fill the system with the mixed solution in the amount the directions require.
3. Run a pump in a loop, with the inlet and outlet each going to or from a bucket or container.
4. With no pump, let the mixture soak in the system for 4 to 8 hours.
5. Keep the system open to air, because gassing during descaling needs ventilation.

What else the job needs

Good to have on hand: a pump and a container or bucket for the loop setup in the directions.
