Whatever floats your boat. Some even alternate chains...have one clean in waiting and rotate them. Most like myself opt for a simple cleaning on the bike as they have learned there is little benefit in being more meticulous. I would be if value were realized. White lightening is supposed to exfoliate dirt and contamination and it does a relatively good job of doing so. Of course soaking a chain will liberate internal contamination better than a topical wiping. At the end of the day I think you will find as we learn anecdotally from fellow riders...if you performed a controlled experiment with meticulous cleaning by removing the chain versus running a chain always on the bike and not even cleaning the chain with mineral spirits which does little to purge internal contamination...that the net result would be virtually no difference in driveline wear between either technique. I go big miles with keeping the chain on my bikes and BTW my rear cassettes stay very clean and front chain rings stay relatively clean as well.
Personal preference more than discernible benefit except for time lost to remove a chain and clean it.
