When I first got my revomaze open it seemed like it was some sorts of light lubricant on the different parts in it.
I now have opened and closed it so many times that there is probably no lubricant left in the maze, i can tell since i can see the track i follow in the maze very easily.
Is there any recomenations for some kind of oil (or something else) to use in the revomaze so it reduses wear on the pins and the maze?
I really enjoid the puzzle and i want it to last many many years...
