Steps

Clogged Air Filter
This works for fiber material filters, not paper filters. Several air filters can be cleaned with one batch of Cobra Clean.

Get a Plastic Drum large enough for the filter.

Get 2 bricks or 2 inch square tubing to place on the bottom of drum to set the filter on. A steel rack can also be used.

Place filter on top of rack and fill with Cobra Clean. You want enough Cobra Clean to completely submerge it.

Let soak over night.

The next day, remove filter and place in wash area. Flush with low pressure water hose (no nozzle) until clean. Make sure to flush from all sides.

Let air dry in the sun or shop. Heating the filter with hot air can destroy it. Oil the filter if required.

Reinstall and go for steak dinner with shop crew.
