Observations of EvapoRust or "No Blue For You"

[Andrew Gorman]

I used molasses- 10% solution in water, soak for a few weeks on a chain and it worked great. Just sealed it up in a plastic shoebox on the back porch so no mess. Here's an after picture:

I guess I am primitive.I use a drill press with wire wheel then use "White Lightning"

No before photo because I was not anticipating the result but it looked just like the one in the photo. No doubt it was a blue link chain and no doubt it took the blue off completely. Next time it's molasses for me on the blue diamond chain and a biscuit.

Some Diamond chains were not blued originally. Do you have a picture of the chain before evaporust?

Bummer. I left a nice one in Zep purple degreaser overnight by accident, cooked all the bluing off that one too.

It hasn't been determined if molasses would offset the problem. It doesn't sound like it, based on Duck's post in this thread.

Ive have used Evaporust before and it worked ok. But when i do my chains i use Vinegar works just as good if not better!!

A few weeks! I guess what they say about molasses is true ,very slow.

When do you need to get this bike on the road? besides, the hydrangeas like the iron.

No surprise there- "bluing" is, technically, a controlled rusting process. Google "rust bluing"; I've done several firearms with beautiful results, using the process.

Exactly- bluing and plum browning are both forms of controlled corrosion using different chemicals. Oxalic Acid likewise will lift most forms of bluing and plum browning. I have had luck using long soaks in detergent motor or gear oil combined with a stiff bristle, plastic brush for removing rust and gunk from chains without removing bluing.

If you don't want to soak, try gun oil or, better yet, Balistol with brush. When you're working with bluing, gun care products are your best bet because they have largely been formulated not to remove bluing.

Has anyone tried molasses yet on a blue chain?
Also, has anyone figured out what's in Evaporust? I haven't been able to find any info on its ingredients. It's not acidic and it seems to be water-based. It sure looks like the 10% molasses solution but it works a lot slower.
