i use a bucket of hot water, and walmart spray lube to displace the water on the chain, otherwise the next day you will find rust on the chain. that was before fenders and with a particularly nasty collection of sand a salt. unfortunately winter riding requires close and frequent attention to chain maintenance, which makes wd40 or a similar product very useful. i have not searched for a long term solution to lube the chain during the winter since it collects sand and salt so quickly. even running a dry chain with the dupont teflon dry lube doesn't work well in winter conditions.
