How often should I be waxing and cleansing?
If the wax you are using is of a high quality (like our wax), and the car is garaged most of the time, then you could get away with maybe two to three times per year. Some of our cars NEVER see the elements and are garaged out of direct sunlight in a cool dry area, they only need to be waxed once a year max. On the other end of the spectrum, our work van, ute and regular race cars need waxing every other month. More frequently in the hotter and usually wetter summer months as the environment and heat does a good job at breaking it down.
The trick is to be honest with yourself and assess how much you use your car. If it cops all of the elements, lives outside and is driven every day, then you will only keep it looking its absolute best if it's waxed every month. You could get away with every second month, but then it wouldn't be looking too sharp after a few years. Another plus for waxing the car regularly is that you don't have to cleanse every single time. I do the bonnet every time with both cleanser then wax, as it cops the most heat, bugs and grime on the car. But the rest of my cars gets by with a good wash and loving wax. If you let the wax deteriorate away you will need to re-cleanse.
