The cleaner really only needs to be used a couple of times a year, maybe more in a roadster with the top down a lot (like mine ). The conditioner should be used once a month, and a light treatment is all that's needed. Don't get in the mindset that so many do - if some is good more is better. That's just not the case with care car products. Maybe if you're talking about cash in my pocket, but not car care products.
