I'm kind of curious how everyone applies their Boeshield chain lube. I've read suggestions on cleaning the chain squeaky clean before application... is that necessary? If so, what method have you found effective to clean the chain? What products have you used to clean the chain?

Thanks

I use the Park tool chain cleaner, and I usually just apply a small amount of lube in the process of gearing up before a ride at the trail head.
