Hi,

I have an old beater that has some rust on the frame. I hear that coke can be used to dissolve the rust. Just wondering, is a better way?

My plan:
Put some coke on the rust - leave for a few minutes
Rub off with a cloth and maybe some steel wool
Paint with a clear coat

Does this sound ok?

Thanks

Daven

brass wheel on my rotary tool worked great for me. Handlebars, fenders, wheels on multiple bikes this winter. Some chrome polisher after that. Worked on painted surfaces too. Key is to keep the speed at the lowest you can, and wear safety goggles. The wheel comes apart as it is used.

Thanks will give it a go this weekend if I can find a brass wheel.

Oxalic Acid bath? https://en.wikipedia.org/wiki/Oxalic_acid

This seems to be pretty popular for rust removal.

The "active" ingredient in Coke is Phosphoric acid, which is what does the rust removal. You can buy Phosphoric Acid at the hardware or marine supply store and not have to deal with cleaning off sticky sugar residue. Also you can mix with water in a higher concentration than found in coke for faster and better rust removal.

Caution though, it is after all, acid. Wear gloves, safety glasses, etc. Phosphoric acid seems to work faster when exposed to sunlight as a side note. Also be careful what you get it on. Plastic and rubber components may not fare well, depending on their formulation.

It is used on ships extensively with great success.

Let us know how it goes, and maybe some before and after pics.

Oven cleaner, some fine grit sandpaper, some very fine grit sandpaper, and some metal polish....

Also a good way to get nasty scrapes out of parts.

Just dont leave it on there to long or it may eat more than you want to....

a brass brush has worked very well for me to get rid of surface rust... safe on paint too! wear a mask when using it though unless you like to inhale rust dust (bad)

steel wool would also probably work without the coke

and of course always apply elbow grease liberally

If the part can be submerged (small parts in a bucket, frame with parts removed in a kiddie pool) then oxalic acid does a truly wonderful job. Search the forum and take a look at some of the before and after pictures. I have used it and think it is the least effort way to remove all the rust and leave things looking as good as they can.
