Learn how to correctly clean K&N filter, and how to correctly lube them, hence not how to over lube them to end up with oil on the Maf sensor isntead.
As for cleaning them, can get the recharge kit, but simple green works very well to clean them instead. As for lube, want to use the correct sticky lube, since it's really the lube that is collecting most of the dust with the K&N filters.
Myself, since you can over lube the K&n's and end up having to pull the Maf to clean it as well (get use to cleaning the Maf sensor every time you clean the filters) I just run the Wix/Napa gold dry filters isntead. They do a better job at pulling dust before it makes it to the motor, and since they are white'ish, can see when it time to change then isntead. Also to point out, the K&N's actually filter better being a little dirty, then freshly cleaned and oil instead.
Note, both the wix. OEM and K&N filter flow more air that the engine needs, so it just a matter of which ones do the best of filtering. The OEM do a great job as well like the Wix/Naps golds (they are the same filter), but since the OEM's are dark, harder to see when they are dirty from a glace instead.
And no, I don't hate the K&N filters. I have one on my Harley, since the Harley motor will dump a touch of oil through the breather into the air filter. So if you use a dry filter, it end up getting oil on it take it out semi quickly, while with the oiled K&N, the motor oil vapors that make it to filter, don't harm it in the least.

Either run the K&N filter as is until it's very dirty, or switch to a dry filter.
The K&N filters for the C6 can go 50,000 to 70,000 miles between cleanings. They need to be really dirty before they need cleaning. People (especially Corvette people ) tend to overclean K&N filters. That can seriously shorten the life of the filters, leading to various issues with the media and fsilures. Also, K&N filters actually do better filtration when they are moderately dirty.
If the dirt on a K&N filter isn't caked on to the point where the screen isn't visible, it doesn't need to be cleaned, and there's no benefit to cleaning it.
