It is especially recommended to retain manoeuvrability for valves, shut-off taps, hose adapters, sealing rings and much more. The EHEIM maintenance spray is silicon-based, water neutral, CFC-free, does not contain solvents or oils and is free from environmentally toxic substances. Supplied with spray tube for reaching even inaccessible areas.
