A bit of scrubbing & oil to help, & don't forget to neutralize the acid to stop the coke dissolving it to a relic perhaps?

Salaams spiral.. Well I reckon a week... however the simple thing to do is drop it in for a few hours and have a look... if it isn't working try it again for another 2 hours ... I find coke pretty safe to use but add the safety precaution above. Coke is not so aggressive as to eat the shield in a few days ... maybe our coke is less powerful than yours?... I don't drink coke ... if it does this to rust what about the intestines!

A lot of other stuff is good including tomato paste. I have good results from pineapple juice also. I suspect that much of the entire front is decorated in some sort of scroll work and the shield may benefit from partial cleaning say... the central disc to see how it goes.

I would avoid vinegar especially the hot technique and stick with the soft options as above~ hot soapy water gentle cleaning in coke for a test period of a few hours and so on... repeat as required and don't leave the coke or other mixes where cat/dog or children can have a mouthful.

Recently I've had very surprising success with undiluted windex. When you buy the "industrial strength" stuff in a big bottle you're supposed to dilute it with water before using, but if you use it straight it seems to work quite well at removing rust. I assume it's the ammonia or some other cleaning agent doing the work. Also of note, when you wipe the windex off the rust on the paper towel is brown whereas if you use something acidic like coke the rust on the towel is black.
