lol somebody is really surfing this forums as lately right steve?
remember the red copper type looking that i mention on the ek topic well thats what he ended with lol
theres not...... i will expend all this money on this machine and it will do all the job for me type of deal..
cheapo way to do that with same effects boil your copper piece on water with vinegar you will end with similar results but faster and way cheaper...
you still need some elbow grease to polish the copper.
i do not recommend using mothers inside where the fin area is... if you dont know how to get the residue off that the mother cream leave without reverting to boiling it again lol "red looking copper piece again"... but it will clean it spotless and shiny copper like it aint nothing lol
as you dont want that residue mothers cream leave inside your loop.. alot of bare cleaning with alcohol/water after to remove the protective layer and residues from the fins..
thats why i prefer copper easiest metal to clean in this circunstances... now nickel... well dont use mothers IN ANY PLATED metal surfaces.. XD
also, if the nickel is bad ((cough EK cough)) when you using cleaning methods like toothpaste and brush etc you are eating away the plating little by little and all it takes is a little "microscopic" / "imperfection" entrance to the bare copper/brass and it will mess it up just like that eventually..
you can also clean the stuff with electrolysis but now thats more complicated ""maybe dangerous process"" lol
now if you really love your block that much you can plate this yourself.. this is a summary on howto..
you can also remove the plating if is messed up XD
