Scale build up is a common occurrence in marine equipment.  It's just a fact of life.

Removing that scale helps prevent overheating, reduce fuel costs, and reduce the chances of unexpected failures and expensive repairs.

Hammerhead Marine Descaler can be used to clean anything that has a scale problem - raw water coolers, heat exchangers, boilers, outboard engines, piping, water heaters, marine A/C coils

Traditionally, harsh acids are used to remove that scale which is effective, but ....

there is risk of damaging the equipment due to corrosion.  Hammerhead is made without harsh acid and has one of the widest compatibilities on the market including:

Aluminum

Copper/Copper-Ni

Gaskets & soft materials

Which means... it's MUCH EASIER TO USE, REDUCES RISK OF SERIOUS INJURY, and DOESN'T CREATE A HAZARDOUS INCIDENT IF SPILLED.
