| I am new to the cube world and would like some advice on how best to maintain a cube. I have seen differing opinions on You Tube about how to lube the inner parts of the cube. I was attempting to clean up an older cube and used WD40. After about 30 minutes of it not getting any better, I took it apart and used alcohol to clean all the parts. I re-lubed everything with silicon but when I was putting it back together, the core just fell apart. The plastic core just crumbled away. So I have two questions: 1) what should be used to lube a cube and 2) where can I purchase a 3x3 Rubik's core? I saw one core for sale on Cubes4You.com but I don't know if it is the correct type. It doesn't look like the one that fell apart on me. Thanks for your help/advice! |
