AFE Filter won't come clean!!

[Challenger-II]

I have an AFE drop in filter that I am having a problem getting clean. I have cleaned it 4-5 times and used up 2/3 of the bottle of cleaner. There still is chunks of embedded grime in the screening. Is it normal to see a large stained circle area on the filter even after cleaning? Maybe with a filter of this size, it should be soaked instead of sprayed with that rinky dink little spray bottle? Any help would be appreciated.

Maybe use a garden hose? Spray into the clean side.

Could be you're expecting it to be cleaner than it really needs to be. Oil type filters filter better when dirtier up to the point that they start restricting airflow. Over cleaning reduces their life.

I had the same problem with my AFE. I tried and tried to clean it completely and finally just gave up. I feel your frustration. I think it says to soak the filter if necessary. Good luck.
