Gently shake off and brush away excess dirt. Spray on AIRAID Cleaning Solution so that the filter is fully saturated, and let soak for 10 minutes. Rinse filter from the inside out until the water comes through clear. Use only low pressure from a tap or garden hose.
Allow filter to air dry. A fan may be used to speed up the process. DO NOT use heated air blowers, compressed air or open flame.
3. Apply Oil
* Not necessary with SynthaMax® Filter.
Make one careful application of AIRAID Performance Oil to each filter pleat on the outside of the filter only. Allow oil to seep into the filter for 20 minutes. Lightly re-oil any areas that still appear dry.
