Recommended by mechanical experts for outboard and inboard engines.
● Removes scale deposits in cooling systems, heat exchangers, mechanisms, pumps, propellers and engine’s tail.
● Suitable for aluminum and bronze.
● Does not damage rubber, gaskets, or seals.
● Neutral odor.
Applications:
● Immersion: For small components, soak them directly in a container with DE-20. It can also be used by filling completely the cooling system and letting it work.
Recirculation:
● Outboard: Mix in bucket, DE-20 with fresh water and place it under the propeller. Start the engine and let it absorb the mixture through the water inlet and circulate for about 15 minutes.
● Inboard: A pumping system is needed to inject DE-20 and recover it for recirculation. Depending on the extent of scaling, use a solution of 25-50% with fresh water and don't exceed 45 minutes of applitacion. The solution has a red colour which disappear when it is neutralised.
