You can either buy filter cleaner or use gas, either way they will both clean the filter. You will need a 5 gallon bucket or a large plastic bag. It is best to clean several filters at once, because it is a dirty job. Fill the bucket with a little bit of gas or cleaner and place the filters in. Soak the filter in the cleaner for about five mins. Then carefully squeeze the excess liquid and dirt from the filter. Be careful not to tear the filter. Repeat if necessary. Allow the filter(s) to dry then soak them with filter oil. A good air filter should last through several cleanings.
