When the engine overheating is the least of your problems

What you need to know

Marine engines use seawater in their cooling system.
As a result, the system is exposed to calcium, rust, barnacles and other mineral deposits that cause cooling tubes to clog. Exposing your engine to more load, increased fuel consumption and decreasing the motor life expectancy.
As the above build up can damage expansive parts of your engine, it is recommended to use RYDLYME MARINE on a regular basis.
Simply circulate RYDLYME MARINE through the cooling system to dissolve all marine growth.

Why Rydlyme Marine?

Saves Time & Money

RYDLYME MARINE has saved companies millions of dollars in operational costs and downtime for over 78 years.


RYDLYME MARINE is 100% biodegradable making it the safest and most environmentally friendly descaler on the market.

Simple and Effective

Just dilute RYDLYME MARINE with water and it is ready to go. You will start to see results within minutes.

Water scale, lime and rust deposits are a serious problem for virtually all Marine industries where equipment is exposed to either fresh or sea water.

Once systems and equipment become fouled with scale, efficiency decreases, energy costs increase and the useful life of equipment is diminished. Failure to address water scale problems in a timely manner runs the serious risk of costly equipment or system shutdowns, repairs, or even replacement.

RYDLYME MARINE is the safest, most simple and economical solution to your scale, rust or lime problem, keeping your equipment operating with maximum efficiency.

How Rydlyme works

RYDLYME’s unique formula, created in 1942 is a mixture of 100% biodegradable wetting and penetrating agents that quickly dissolve scale from pipes and equipment within minutes. The solution can be diluted with water to the preferred concentration needed for best results and simply flushed with water after cleaning. This is why RYDLYME MARINE is the “World’s leading biodegradable descaler!”
