i recently purchased a cube4you brand pre-assembled white cube, and right out of the box it turned amazingly and had this clicking sound after each individual turn that was helpful. I dont know how or why, but i ended up lubricating the cube and changing the tensions, my silicone spray has petroleum distillate, so today i sprayed some silicone into a container and waited an hour so that the petroleum distillate would evaporate, then i took a clean new paintbrush and brushed the petroleum-free silicone onto each piece. after working it on for approximately one hour, it turns much worse than the silicone spray that i didnt spray into a container first...any explanation? does anyone know how i can get my cube to how it was when i first baught it?
