Tip 2: Coat the air box: We recommend WD-40 or penetrating fluid, this makes it easy to wipe out as well as leaves a film to catch dust before it gets to the filter. Think, every bit of dust that doesn't make it to the filter means a cleaner filter…
You can use any oil, but sticky filter oil would probably do the best job. WD-40 is a poor product for airfilter elements. (Unless you're trying to displace water out of the element.) And then the aromatics used in the aerosolization process would attack the foam itself, causing fracturing of foam. That would be bad.
Apply WD-40 degreaser generously on the filter. Alternately, use warm soap water. Scrub it, generally with your hand or a plastic bristle brush is alright. Wash it with plenty water - About 3 minutes of free flowing water under tap in opposite direction of functional air flow.
You shouldn't spray anything into the inlet manifold for that matter. WD40 is mostly solvent, it's actual oil content is VERY low.
You should avoid using solvents or kerosene for this reason. Simple Green All-Purpose Cleaner is aggressive on grease and heavy soils but is gentle enough to clean air filters without harming the filter material or causing damage to surfaces found on automotive equipment.
However, you might already have a simple tool you can use to clean your K&N cabin air filter: Dawn dish detergent. If it's safe enough to bathe ducklings, it's certainly suitable for your air filters. Its concentrated formula removes grease, dirt, and grime, and it rinses clean away — unlike some detergents.
We find brake clean works really well to remove the old air filter oil, grease and dirt from the air box. A good trick is to stuff a clean rag inside the air boot so if some dirt does fall in there it will be caught and not end up in your engine later.
Seriously, use the proper cleaner and oil. WD-40 partially evaporates and the lubricant is not a match for filter oil.
Inhalation: High concentrations may cause nasal and respiratory irritation and central nervous system effects such as headache, dizziness and nausea. Intentional abuse may be harmful or fatal. Skin Contact: Prolonged and/or repeated contact may produce mild irritation and defatting with possible dermatitis.
Whether cruising down a clean street or bombing through a silty desert, air filters keep dust and other contaminants from being sucked through the intake and into the cylinders, leading to oil contamination, damage to the turbine wheels and bearings in forced-induction applications, or gouges in cylinder walls.
Vacuum Clean – A few passes of a vacuum cleaner will remove accumulated dust and dirt in seconds. Blow with Compressed Air – Point compressed air nozzle in opposite direction of operating air flow (blow from exhaust side toward intake side).
Not every filter can be reused; HEPA filters and soft, pleated filters usually cannot be reused based on their design. If the material is made with something like fiberglass, it is pointless to reuse the filter, because of how it traps particles. The truth is, the more powerful air filters are usually disposable ones.
Plant-based oils make cleaning filters easier. (3) Motor oil. If you are in a real pinch, you could use regular motor oil on your air filter. It is better than nothing.
If you need a deeper clean, fill your sink with one part vinegar and one part warm water, then let your filter soak for an hour. If your HVAC filter is only mildly dirty, place the filter in a sink or bathtub and rinse thoroughly with warm running water.
Look for oils that are high-quality, easy to apply, combat rust, resist blowout, dissolve gunk and won't harm your rubber seals. And never, ever use WD-40, compressor oil, 3 in-1 oil or those lubricants not specifically designed for pneumatic tools.
Cut down on snow shoveling time with this neat trick: Spray the original WD-40 formula on both sides of your shovel before you start. Watch snow, ice and slush slide off the surface. No more stopping every few steps to dislodge built-up snow from your shovel.
Yes it is! If you spray a roach directly with WD-40, you can instantly kill it! Moreover, you can spray it on frames, windowsills, doors and screens to keep bugs out of the house. Do be careful not to breathe in the fumes of the spray and it is better not to attempt this while there are children in the house.
WD-40 doesn't have the same viscosity as traditional grease or oil, and it can erode certain finishes, and it can cause problems when used as a substitute.
Tip 2: Coat the air box: We recommend WD-40 or penetrating fluid, this makes it easy to wipe out as well as leaves a film to catch dust before it gets to the filter. Think, every bit of dust that doesn't make it to the filter means a cleaner filter…
Use only K&N oil, and never saturate the filter. If oil drips from the filter, allow the filter to sit for several minutes until it stops dripping, and then wipe any excess oil from the filter frame.
The easiest way to clean a car air filter is with a vacuum cleaner. Connect the hose attachment to your standard household vacuum, and you've got the perfect tool for getting into the ridges of the filter itself.
You should avoid using solvents or kerosene for this reason. Extreme Simple Green Motorsports Cleaner and Degreaser is aggressive on grease and heavy soils, but is gentle enough to clean air filters without harming the filter material or causing damage to the high-performance surfaces found on motorsports equipment.
You can use a gentle brush and mild detergent to wash off sticky particles. Once that's done, shake the excess water so it drains out of the drain holes in the frame, and reinstall the air filter back into the system. The airflow from the system will dry the clean filter completely.
