Arch said:Rust off the bike, or off the chain? If the chain is really rusty, splash out on a new one (you'll need to note how many sprockets you have, to get one the right width)
No sure what to advise about cleaning, I think everyone has their best methods. You're probably not going to hurt it much with washing up liquid, or cream cleaner, esp if, as you say, you rinse it well. Just beware of using anything too abrasive, so that you scratch the piant and potentially let more rust get hold. I use Muck-off spray on my bikes (mainly to shift the really greasy crud that builds up around the sprockets), but I know some people hate it. Mind you, I only really clean my bikes once a year.
For lube, I use Finish Line (or the Halfords own brand equivalent), comes in bottles like this. Finer than oil, less sticky - comes in 'wet' (green top) and 'dry' (red top) types, I find the dry is adequate for my day to day riding. Again, others will have a favourite to recommend.
Rust on the bike and the chain! I think it might be okay if I give it a clean. Will pop down to Halfords and get some of that Finish Line stuff. Do I need anything else for the other parts, like oil or grease? It's 3 for 2 and I'd rather get them all at once.
I know what you mean about reaching out and explaining. I do appreciate all your help though! It just is incredibly useful to see it properly, and being able to see it on my bikes helps too.
