K&N Air Filter Cleaner & Degreaser — Power Kleen 32 oz Trigger Spray, Safe for Oiled Cotton Filters, Restores Airflow

K&N Power Kleen 32 oz Trigger Spray is a purpose-made degreaser that safely dissolves oil and grime from oiled K&N cotton air filters to restore airflow and performance.

Designed specifically for K&N oiled cotton-media filters, Power Kleen removes built-up dirt, old filter oil, road grime, and grease so the filter can be rinsed and re-oiled. Using the manufacturer-recommended cleaning solution preserves filter life and avoids damage that can occur with solvents like gasoline or household cleaners. This trigger-spray bottle gives targeted application for motorcycles, cars, trucks, and off-road filters, and is not intended for polished or anodized aluminum surfaces.

How does Power Kleen remove old oil and grime without harming the filter?

Power Kleen is formulated to dissolve and lift oil-embedded particles from the cotton media so contaminants can be rinsed away. Its degreasing action separates trapped oil and particulates without weakening the filter fibers when used as directed.

• Breaks down old filter oil and road grime for effective rinsing
• Safe for K&N oiled cotton media when used according to instructions
• Spray trigger lets you control application and limit overspray

Will using Power Kleen help my engine breathe like new again?

Cleaning with Power Kleen removes clogging debris so airflow through the filter improves, helping the filter perform closer to its original specification. Restored airflow supports the designed filtration efficiency and helps maintain engine performance when the filter is re-oiled correctly.

• Eliminates trapped dust and oil that reduce airflow
• Helps restore filter efficiency when followed by K&N re-oiling
• Recommended by K&N to keep warranty intact

How do I use the 32 oz trigger spray safely and effectively?

Spray generously over both sides of the filter and let dwell so the cleaner dissolves oils and deposits; then rinse with low-pressure water until the runoff is clear. Allow the filter to dry fully before applying K&N oil and reinstalling—never use gasoline or abrasive solvents.

• Spray, soak briefly, then rinse thoroughly with water
• Air-dry completely before re-oiling and reinstalling
• Avoid use on polished or anodized aluminum parts

What precautions keep my warranty and filter intact?

Only use K&N Power Kleen on oiled K&N cotton filters to maintain the manufacturer’s recommendation and protect the warranty. Do not substitute household degreasers or petrol-based cleaners, and avoid contact with certain metal finishes.

• Use only on K&N oiled cotton media filters to preserve warranty
• Do not clean with gasoline or harsh solvents that degrade media
• Keep product off polished or anodized aluminum surfaces
