Hi Jannisa

After reading this I realize that WD40 is not actually a lubricant:

And it made me think twice about using this petroleum-based products on rubber. It is said that WD40 will dry out the rubber as it displaces water, and also attract dust over time.

Any special reason you do not use silicon spray? I am asking because I just ran out of it, and now I only have some WD40 left.
