Storeboughts can't be adjusted the way DIY cubes can to solve that problem. I'd recommend a squirt of silicone spray, but if your cube is that tight, silicone acts more like a glue than a lubricant because of the way it behaves under pressure when wet. Silicone is best when your cube is loose to start with and helps it get faster. If it's tight, you're kinda stuffed!
