Heyy i got a rubiks cube and watched youtube tutorials they do so fast. So i came to know that to make your Cube faster insert some lubricant. My friend Add some Vaseline in it and it broke. People online is saying dont put Vaseline, put Lubricants such as Silicone Spray or some spray named Jiga-aloo..... I was thinking that wD-40 is also a Lubricant why not spray into the cube. Will it be fine. Or it'll be breaked like Vaseline .. ?
