To clean an oiled air filter, you'll need to knock out loose debris, then liberally saturate the filter, inside and out, with filter cleaner.
Here's a breakdown of the process:
-
Remove Loose Debris: Gently knock the filter against a clean surface to dislodge any large particles of dirt or debris. Be careful not to damage the filter material.
-
Apply Filter Cleaner: Use a dedicated air filter cleaner. These cleaners are specifically formulated to dissolve the filter oil and trapped dirt without harming the filter material. Spray the cleaner liberally, both on the inside and outside of the filter, ensuring complete saturation.
-
Allow the Cleaner to Soak: Let the cleaner soak into the filter for the time recommended on the cleaner's instructions. This allows the cleaner to effectively dissolve the oil and dirt.
-
Rinse the Filter: Rinse the filter with cool water from the inside out. Avoid using high-pressure water, as this can damage the filter media. Continue rinsing until the water runs clear.
-
Dry the Filter: Allow the filter to air dry completely. Do not use compressed air or a heat source, as this can also damage the filter. This can take several hours, or even overnight.
-
Re-oil the Filter: Once the filter is completely dry, re-oil it with a dedicated air filter oil. Apply the oil evenly across the entire filter surface, following the oil manufacturer's instructions. Allow the oil to soak in for about 20 minutes, then blot off any excess.
Important Considerations:
- Use dedicated products: Always use air filter cleaner and air filter oil specifically designed for oiled air filters.
- Avoid harsh chemicals: Do not use gasoline, solvents, or other harsh chemicals to clean the filter, as they can damage the filter material.
- Proper drying: Ensure the filter is completely dry before re-oiling to prevent mold or mildew growth.
- Follow manufacturer's instructions: Always refer to the specific instructions provided by the filter and cleaning/oiling product manufacturers.
