I have a can of electrical contact cleaner I use, forget the brand, but it is a white can with blue and red writing on it. I have used WD40 successfully also though.
As for the hose, yes it is an aftermarket item. I think I got mine from Chromeworld or something.

Berryman.
I think the name of the contact cleaner I use is Berryman.
And I was mistaken on the hose, also. I missed the model of the bike.
