I like WD-40 as a cleaner but I always spray it on a rag and wipe the chain down. I worry that spraying it liberally on the chain it might seep past the O rings and thin the grease in the rollers. Afterwards I spray on Dupont Chain Saver and wipe off the excess. This has proven to work very well on all my chain drive bikes. The Dupont product does not collect grit and does not fling off on the rear wheel. When I used conventional chain lubes years ago, my chains often were binding and needing replacement in as little as 6000 miles.
