Cross-posted (DIY tribe)
I'm restoring a '79 CB750K and last week I ended up following a bad suggestion to clean the carburetors.
I've boiled the bodies (4) for three hours in a large aluminum pot filled with water and vinegar/CLR.
The carbs are clean now BUT they turned black (reading more I found that the issue was the use of an aluminum pot instead of a steel one).
I am not a fan of shiny bikes, but now I have carburetors with aluminum colored top and bottom and a black body. Not good.
Any suggestion on how to remove the black stain?
The cleaning must be chemical or electrolytic since due to the intricate structure I don't have access with a rug or a brush to all the surface.
I've already tried the carb cleaner spray and the carb dip (2 nights soaking) and they didn't do much.
