First Oa Bath Question

[SirMike1983]

Warmer water will tend to work faster, but if you get it too warm, it can give off fumes. I like water that is warm to the touch, but not boiling hot. A warmer, stronger solution will require you to adjust the time you leave the part in to soak. Never leave painted parts unattended until you are sure of the effect of the solution on your particular paint finish.

I've got a question. Newbie in restoring a bike. If it's a completely rusted bike is this the method? But what if it's say 50-50 on rust to still having paint? Will the OA bath eliminate the paint too?? Thanks for insight to this!!

Try some marvels mystery oil. See if that doesn't work for you.

If your bike is badly rusted, OX, or lime juice is the way to go... more than enough info here on it. However, the Oxalic Acid is water based. Once you start wiping any kind of oil on your parts, the dried out paint and rust absorbs it and the Oxalic acid will not work. Ox usually fades , and sometimes turns red paint pink. Not the best to use on chrome. The yellow residue is hard to get off, there are much safer products available from your hardware store.

The “yellow” referred to in previous posts suggests to me that the OA is eating into the chrome on the parts enough to release chromatic acid which is used in the original chrome plating process...proceed with caution, that stuff is dangerous...do not breath it. If you’ve ever taken a 50 cent tour of your local plating shop,that’s why the chrome bath looks, for lack of a better term,golden or deep yellow. Also... lead was used in a lot of old paint...be aware of what you are dealing with. Chrome reflects blue,nickel,underneath the chrome,reflects yellow. You may be removing chrome down to nickel. If you see copper,you’ve removed both chrome and nickel...hope this helps.
