Have used your air filters for over 30 years. I even installed one on my 2006 Southwind RV. As I don't put a lot of miles on my cars, I clean the filter about every 5 to 10 thousand miles. This time I bought both of your products for cleaning the filter. Originally, you only had one cleaner. Maybe one of these is oil that you apply after you clean. I seem to remember I used to spray water, then apply oil.
