when you properly degrease your chain and see the amount of grit that comes out of it ,imo,you realise that it is worth doing.once clean i then submerse it in oil in a small container ie.washed out chinese takeaway container. once it has been submersed for a few hours i then dry it off with rag as much as possible so its not too wet when it goes back on the bike. this should replace some of the oil back into the rollers.
you can also keep the oil in the container and reuse it next time.
