I have oiled my Powerball...

Reason: The oil has instantly destroyed the internal friction in your Powerball and friction between the rotor support band and the internal sphere surface is that one vital characteristic which helps to convert your wrist action into rotor speed!

Solution: Open the Powerball and clean ALL component surface areas with a pure isopropyl alcohol solution.

Detailed Explanation: The principle of operation on your Powerball is based on the resistance that occurs between the rotor support band and the surface of the inner sphere in which it resides - if this resistance is minimised by even a tiny application of oil then the ball will no longer respond to your wrist movements and rotor will spin lifelessly inside the sphere (generally going nowhere and making you very frustrated indeed!)

If something like this has occurred then you've got to open the ball up (as indicated here) and take it apart to base component level; get some pure alcohol and start cleaning each and every component surface but paying particular attention to the entire rotor support ring and the actual surface areas on the inner sphere on which the rotor support band sits. Make sure you use a pure, non solvent solution (preferably alcohol based to ensure that it evaporates after the process and leaves no residues behind) otherwise you will melt the surface areas.

So I repeat...no oil...ever!
