Valma Slot Free prevents you from standing in front of a closed door. The Valma lock defroster defrosts and lubricates locks. The liquid not only thaws, but also prevents the lock from freezing again due to the addition of Glycol. The defroster is packaged in a handy squeeze bottle and can therefore easily be sprayed into the lock. After a few seconds, the key can be inserted in the lock to open the door.
TIP: Do not leave the defroster in the car, there is nothing so annoying that the lock is frozen and you cannot reach the lock defroster!
