Belgium and the Netherlands approve Hydrex for propeller cleaning method
Hydrex has obtained permits to clean propeller blades in Belgium and the Netherlands

Hydrex has been granted approval by Belgium and the Netherlands for its underwater propeller cleaning method, which uses a light tool to buff the propeller.

The traditional approach to propeller cleaning is to polish the blades with a grinding disk, which can damage the propeller. Using a grinding disk can remove substantial amounts of metal from the blades. This makes polishing a source of marine pollution, which is a problem in ports.

The buffing method removes material build up carefully without damaging the propeller. This ensures the propeller is kept as smooth as possible, which reduces friction through water and improves fuel consumption.

According to Hydrex, its propeller buffing method complies with the strict environmental regulations in both countries.

A large number of ports, including those in Belgium and the Netherlands, have banned the underwater cleaning on propeller blades. Exceptions are only made for those companies that can pass the very stringent tests carried out by the concerning authorities.
