Maybe I'm just doing it really badly but my regime takes about 1 minute and I have the same chain and sprockets from new with 13,000 miles so far and little rust on the plates:
Upon returning from a ride I put the rear on the paddock stand and select neutral.
I get some workshop paper towelling and lay it on top of the rear section of the Carbon belly pan to catch excess fluids, making sure it does not catch the rear tyre.
I then spin the wheel gently whilst spraying wurth brake and chain cleaner into the chain, inside to out, directed towards where the paper towel is.
Might give the chain a wipe although generally the force of the spray does the job.
Wait 30 seconds (shaking the wurth dry lube can), then apply dry lube exactly the same way, reversing the chain direction once to ensure a good coating.
Done.
