How to use

  1. Isolate

    Isolate and drain system to be descaled, making sure no raw water can be introduced during the process. Disable compressor or chiller to prevent operation during descaling. Flush system with fresh water to remove any remaining sea water prior to beginning.

  2. Fill & Circulate

    Fill system with the required amount of ready-to-use Descaling Fluid. Set up a recirculating system with a suitable pump in which both inputs and outputs feed/drain solution from a container or bucket. If unable to use a pump, you may also allow product to soak within the system for 4-8 hours. DO NOT seal the system off, as gassing will occur during the process and excess pressure may cause damage.

  3. Drain & Flush

    Drain solution from system and dispose in accordance with local, state and federal laws.

    Flush system with fresh water to remove any remaining descaling fluid, and then reassemble properly. It is recommended to replace all sacrificial anodes at this time.

    For Soaking: Fully submerge equipment in solution for 4-8 hours, or until scale has dissolved. Rinse with fresh water.

    In addition to inboard engines, outboard motors can also benefit from descaling. Mix Marine Descaling Fluid with water according to instructions. Use a flushing attachment to circulate the solution through the outboard motor's cooling system. Run the engine briefly to break down scale deposits, ensuring smooth operation and preventing overheating.
