The best way is the only way - if you want to keep the "Million Mile" Warranty and get the best out of your filter.

Rather than describe, here it is from the manufacturer:

It goes without saying that you're best off using the K&N cleaner and their filter oil.

Basically:

• lightly brush off any loose dirt
  
• Soak the filter medium with cleaner, allow it to stand for 10 minutes (but don't allow it to dry)
  
• Rinse "backwards" (from carb side to outside) with a gentle stream of water.
  
• Allow to dry
  
• Recoat with filter oil
