de-rusting bike chains & sprockets?

What do people here do w/ bikes for other people to help them salvage
their bikes that may have been sitting outside just a little bit too
long and they don't want to spend the money on new sprockets & chains?

What types of chemicals will remove rust?

I'll start, try spraying everything with something like WD-40 to
clean, then use a good oil/lube of your choice. You may get alot of
different responses as to what type of oil/lube to use, i.e.,
everything from 3M oil to motorcycle/car oil to fancy bike lubes like
Boeshield T-9, Tri-flow, Pedros, Prolink (I like this stuff), or
Dumonde (expensive stuff) to name a few. Its basically a *religious
war,* so find something you like or cheap and get out and RIDE!!! Good
Luck!

Steel wool soap pads clean up cogs pretty nicely. I don't mess with
rusty chains, as they're cheap enough to replace. The chains from
*mart work well enough on 7 speed bikes and cost $10. You can get KMC
chains or rebranded KMC chains online from Nashbar for 8 speed that
are excellent, also for $10, often sold two to a box as "tandem"
chains--you can use them for 5/6/7 or eight speed clusters.

If you're removing rust from bare metal or chrome, a wire wheel on a
drill or bench grinder makes it a fast job. Rust under painted areas is
tricker because you don't want to take the paint off with the rust. Use
a "Brillo" type pad and gently remove the loose rust. If the
paint is discolored a little rubbing compound on a soft cloth
can often help. Apply wax over the painted parts to prevent new rust
from forming.

Depending on how rusty the chain is you may just want to bite the
bullet and replace it. If it's just a little surface rust on the side
plates a wire brush should remove it. If the links are frozen, replace
it.

Remember to put some value on your time. Spending 3 hours on a part that
could be replaced for a few bucks doesn't make sense unless it is
something rare or otherwise unobtainable.

Most of these bikes do not need new sprockets and chains, because they
are seldom ridden. The hardware has plenty of miles left in ti. Rust
on the outside of a chain is not necessarily a bad thing. Just like
people, it's what's on the inside that counts. If some of the links
are locked in place with rust, it's often more trouble than it's worth
to loosen them up. Otherwise do it the good way -- remove the chain
with a chain breaker, soak in solvent, brush clean, dry, apply lube,
or do it the quick bad way -- put lots of lube on it ( like motor oil
or my personal favorite, chain saw ) spin the cranks, wipe excess lube
off. While you are at it, remove the seat post and squirt some lube
down the seat post -- if the bottom bracket is one of the old cup and
ball bearing jobs. If so, it will quickly relube the bottom bracket.
Then, you can remove the rear wheel and wipe the gunk off the
sprockets.

It's a good idea to first measure the chain with ruler. the 0 and
the12 inch mark should each be close to the center of one of the pins
of the chain. If your chain is too rusty, rust-welded together, or
too worn, do yourself a favor and get a cheap new one.

3. Quick-glo (a personal favorite).

Oil the chain enough to loosen any stiff links and just ignore the rust.

there are a number of chemicals that will do it, but unfortunately,
there are a sub-set of them which will give you a risk of hydrogen
cracking. best to just oil and ride. or replace. not much point
spending $6 on chemicals and 1 hour of time [not to mention container
clean-up and chemical disposal] on something that can be replaced for $8
and 10 minutes.

If you're not concerned with cosmetics, just add oil to the chain and
ride. The rust doesn't do much harm.
