Also, cotton gauze filter recharge kits sold by K&N and Green all have 2 bottles, a bottle with cleaning agent, and a bottle to re-oil the filters. The sticky oil is what traps the dirt.

An ultrasonic parts cleaner works without doubt since it is mechanically vibrating the debris out. They use ultrasonic cleaners to clean everything from jewelry to shaver blades. Regarding, effervescent soda pop, I'm still not sold on the idea since no one else has posted their results or findings. The club soda way is ONE way, not necessarily the BEST way to clean your filters. I showed my filters to other people and they thought it was brand new.

Also, After I put the filters into the airbox and seal it, I have the fan blowing air thru the baffles to make sure no oil is stuck anywhere.

tried this first...didn't work, didn't do anything...

so i went back and used the green filter cleaner, then the oxy clean and club soda mix, then the filter cleaner, then the oxy clean and club soda, and you get the picture...

after doing this back and forth 5 times and finally scrubbing out the remaining dirt with a tooth brush, my filters were finally clean...

next time, this is what i am going to do...

filter cleaner, scrub it, oxy clean-club soda, repeat as necessary...just my .02
