I know HCL can be used to get rust off a nail, i was just wondering about if it was possible to use hf to get rid of the gunk that is resultant, its a solution of water and iron chloride.

I'm not a chemist so could you explain that to me? What difference would be made if i added hcl aswell?

I know Hf etches alot of materials, but I can't seem to find any information on how it reacts to Fe.
