K&N air filter cleaner comes in liquid or spray-on form. You should apply the liquid K and N air filter cleaner onto the dirty side of the filter and let it soak for 10 minutes before removing it. The large round element must be rotated in the filter cleaner to ensure it gets a complete coat of the product. To clean it, you can either place the air filter in the pan or turn it upside down.
The K&N air filter cleaner is meant to clean a cotton filter element. Do not apply oil to the paper element, as this will weaken the filter’s cotton material. Also, do not use the hairdryer too much, as this will damage the cotton gauze material. Once the K & N air filter cleaner is completely dry, you should oil it before installing it. To ensure the best results, apply it to the dirty side before installing the new one.
After soaking the filter, rinse it thoroughly. For the most thorough cleaning, use K&N air filter cleaner with a soft brush and mild water pressure. The cleaner will be effective in cleaning both synthetic and cotton fiber filters. If you’re using the synthetic filter, you need to check it more frequently. Otherwise, you’ll be voiding your warranty! If the dirty filter is made of cotton, you should wipe it clean more often than if the filter is made of cotton.
How to Use K and N Air Filter Cleaner Spray?
The first thing to do when cleaning a K N air filter is to apply the cleaner. Depending on the type of filter, you might have to apply it in a spray bottle, a jar, or a pan. You need to soak the large round element in the K&N cleaner spray for at least 10 minutes, and then remove it from the intake pipe, OE air box, or custom assembly. Now, you can use the cleaner spray liberally.
If your air filter is reusable, you should remove it from the housing. To do this, you can pull the outer pleats of the filter out, and spray the spray cleaner on them. Make sure to use liberal amounts, and spray both sides. Do not allow the K N air filter cleaner to dry on the filter, and let the filtered air dry completely before reinstalling it.
After you’ve removed the filter, you should rinse it thoroughly with warm water. Be sure to thoroughly rinse the filter after applying the cleaner, and to tap out any heavy dirt. Next, spray liberally with K&N air filter cleaner and filter oil spray, and let it sit for 10 minutes. This way, the K&N cleaner will soak in the filter and prevent it from drying. You can repeat the process as many times as necessary.
