How to deal with rusty chain

[Painkiller]

The best thing is not to let your chain get rusty in the first place. Chains for most 6,7,8 speed bikes can be had for $15 to $20 all day long. For me my first choice is to just replace it and the reason is simple. If finished it does not meet the level of 95%+ perfect it will get replaced. If the chain you are trying to save does not have a quik link then that is an extra cost to figure in the time and labor to remove the rust. It would be a different ball game if it was an antique chain being restored and then there would be even more steps taken to restore that chain. This post is only about users.
Step1. Remove chain and place in ultrasonic machine w/heat setting. This machine will be the difference between a couple days or a half an hour.
Step 2. Remove chain from machine and wash in pot til water runs clean, blow dry, lube, then install. I hang on a nail to lube, let soak in and wipe with a lint free rag that is moistened with my lube.
Following are some before and after pics and the product I use to remove rust. If the chain is stretched, replace it, if it is still good and want to move on with the bike, replace it. they are cheap, faster to replace and finished product is as good as it gets. For bikes that are users why bother, but thats just me.
Time is money for me, what I am showing you here took an hour to do, 5min of my time to put on a new chain and better end result.

Nice to see Evaporust being put to good use.

Note that Evaporust can cause some metal parts to seize. I've soaked chains in and had them come out like this. I would suggest trying to use an Ultrasonic Cleaner to loosen up any fine particle—then oil the chain with your favorite lube—or maybe try dipping it in full synthetic motor oil.

Otherwise, your best bet is to throw the chain away and don't waste your Evaporust.

Try using wax or you may need Rust Inhibitor oil spray to help prevent the chain from flash rusting or normally returning.

I do not think you are reading my post and understanding the jist of it. I totally would not recondition a user chain with a value of !5 to 20 bucks worth of chain. and I use ultrasonic cleaners for restoration purposes for rust and degreasing as step 1. I have zero experiences that you have described with evapo-rust and ultrasonic cleaners and I probably think That I deal with this these things more than the average bike guy does. in any scense of imagination.
