Chris James has it about right....
Theres good reason for keeping your chain 'clean'...whatever that may be...and lubed. But dont lose sight of the fact its just a chain thats relatively cheap to replace.
But theres also other reasons for the obsession with chains...making it look as nice as the rest of the bike. I dont HAVE to remove the chain, blast it with WD, blast it with an airline, wipe, oil, wipe, oil, wipe...you get the picture.........but i WANT to. I want to do it, cos i put a reasonable effort into keeping the bike nice looking...so i WANT to do the same for the chain. And its worth every 15 minutes or so of work i put into it. Ive done it both ways, and i know the chains cleaner when i do it my way.
Mickles way is as good as it gets for minimum effort.
But a little more effort will bring better results....if its important to you, or you can be bothered.
I lube my chain quite regularly...yet the last time i did it, i was horrified at the 'grinding' sound from it AFTER i'd wiped.
I'd only lubed it maybe two weeks previous, and i dont really do that much mileage !!! Another dose of oil, wipe, oil, wipe is not going to magically shift all the debris that was causing the noise. Its quicker to take the chain off and do it my way.
