BUMP!
This is a widely used method for breaking in Rubik's Storebought cubes. Pop an edge and smear the inside with Petroleum Jelly. Play with it 30-60 minutes a day for about 3-5 weeks. After that, Use boiling water to melt out the Petroleum Jelly and spray it with ProStaff D39, Jig-A-Loo or 50k Diff oil. I usually spray Jig-A-loo since it's widely available in Canada and I follow up with 50k diff oil on the core "arms". Reason for Petroleum Jelly; Makes it feel smooth so that you are more likely to play with the cube and it collects the cube dust Edited post! Yeah!.
