Moving parts that are regularly subjected to aquarium water tend to get tight or seize up entirely after some time. Simply applying the spray to the parts concerned quickly rectifies this problem. The maintenance spray is especially recommended to maintain 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 a spray tube to reach even inaccessible areas.
