The Hercules Sludgehammer system restorer and noise reducer provides system cleaning and reduced kittling, while restoring heating system efficiency. Suitable for all metals, the restorer pairs well with Hercules Sludgehammer Universal Corrosion Inhibitor as part of an annual maintenance program. The restorer and noise reducer helps restore system efficiency, and can be used in older boiler systems or when a new boiler is fitted into an existing system with sludge and scale build-up.
