I have been trying a new variation lately...ever since seeing an ad from Maxima (I think it was them...) in a dirt bike magazine for a "chain maintenance kit" consisting of 3 different cans/steps....
The first step was some kind of chain cleaner solvent type spray, which was to be sprayed on and wiped off and then followed with their multi-purpose penetrating spray lube (ala WD-40). The last step, after wiping chain again, is their synthetic chain lube.
I don't know about the 1st step, but I soak my chains with WD 40 after every bike wash, then wipe it off with a rag and finish with a chain lube...it just never occurred to me to do that process every
time I lubed the chain. In the ad, they claimed the 2nd step was the most often overlooked one and that it was very "important" because the coat of penetrating lube actually helped get (they implied "force") the chain lube in to where it needed to be to do it's job...I'm paraphrasing, but that was their basic point. Besides, it's not like they are trying to sell anything...
I have been doing "the process" for about 1000 miles, or a few lubes, and have noticed no real difference--I kind of expected more "fling-off" on my rim and elsewhere, but it hasn't been so. It would be interesting to start with a brand new chain and sprockets and see if there is any long-term benefit to using both
WD 40 and
"regular" chain lube.
I don't think that would work for me because I can get too damn lazy...in the long run, I'd probably just skip straight to the lube about half the time anyway....(there's a metaphor in there somewhere!)
