Thx! I've been wet sanding & using polishing compound on significantly oxidized stems . The manicure block should be much more user friendly.
Keep up with the sanding method when it comes to really deep greening. The finer grades of the manicure block is good for finishing the pipe afterwards. Otherwise you could just purchase micromesh, it’s not too expensive in the long run in comparison to the nail block - actually it’s the same stuff.
Not to mention the acidic acid method… but that’s only for the wicked. And someone told me it’s to “messy” to fuss around.
