What do you all use to clean your air filters? Can I use the same stuff I clean my hot tub filters with? It is some type of cleaner degreaser that I soak them in. My filter is starting to look dirty and I know they can be cleaned but I have never heard just how to do this.
i just spray from the inside out with the garden hose, allow to dry and spray k&n oil on them. ehh...instruction call for soaking filter in cleaner(detergent soap) for 10 min and spray inside out with garden hose, air dry and oil.
