If you don't mind me asking, what do you use to clean the insides of blocks? Nearly every thread says to use vinegar solution/ketchup/lemon juice. All of them are acidic - just different acids. Other threads say to not use Brasso inside the block (which smelled like ammonia).
Thanks just a nickname. I am not sure if I am going to go any further than where I am at. The scratches are minor and I would think paste will mask it. I am switching from am3 to an 1150 so I don't know if the scratches will be in more of a nuisance area now though.
