I've never cleaned a new chain, in almost 60 years of buying a couple of dozen new racing bikes. In fact, I never clean chains, period. I wipe the outside of the chain with a cloth with some light oil on it after the first couple of rides and then again a few times, periodically, until the chain just begins squeaking, which usually happens after 1,000 miles or so.
Then I drip as little as possible of a good lubricant on the chain (currently Muc-Off Hydro-Dynamic), spin the cranks for 20 or 30 revolutions, wipe off the excess, and repeat as described above. Chains stay clean enough and last long enough. Works for me.
