Our non-greasy special care spray PS88 for all locking cylinders – such as door cylinders, bicycle lock cylinders or padlock cylinders – ensures that a locking cylinder remains well maintained inside and that a key can be turned around smoothly. The PS88 spray protects the locking cylinder from dust, dirt and more, making it more durable and longer-lasting. Simply spray it into the locking cylinder and you’re done. Please note: If a locking cylinder is heavily soiled, the dirt will run out afterwards. Therefore, it may be useful to have a cloth ready to catch the dirt.
