Your suppose to do it every 15k miles. Remove the filter and brush off any excess dirt off of the filter. If you used compressed air to blow it off, do not blow directly on it. Blow from the inside out so you don't force dirt into the filter. Generously spray the cleaner over the filter. let sit. Rinse off with water from inside out. Naturally dry filter, do not leave in the sun.
The actually cleaning takes is pretty short, just waiting for the filter to dry. I found the best time to do it is in the evening if im not planning on going out. That way i let the filter dry over night.
Depending on how dirty your filter is, you should notice an improvement on sound and power.
