I just got mine two or three months ago....there's noo way im cleaning mine for a while....in fact i may just order a whole new filter because i really dont like the idea of oil getting all over my MAF...of course the oil is onlya problem if you over oil.
I have had mine on for about 3500 miles, and it was discustingly dirty so I got the cleaner and went to town. It doesn't really say when to do it so I think your good. I have had no problems as of yet, keeping my fingers crossed.
Look at a light source from inside your filter. If the light is easily visible, you don't need to clean, no matter what color your filter looks. If it is not, then time to clean and oil has come...
