OK this will sound weird, I need to find what type of metal some parts are made from

1> The front foot-pegs brackets are made from?
2> Carby Intakes tubes

Reason:
My are terrible, and was going to use a etching type acid cleaner or similar to clean them but need to get the correct type of acid for the metal type.

thanks

Etching compounds with hydrofluoric acid should work. Don't let them sit for more than 30 seconds, flush liberally with water after those 30 seconds, and then brush/scrub without letting the part dry. Reason for the scrub is that a layer of oxide forms and needs to be cleaned off. If let to dry, the part will take on a dark grey weathered finish.

Great post!
I’ll give this one a try. The bike is in urgent need of some serious maintenance and cleaning.
