I'll throw my support for claying in here too.Used one for the first time last month, love it, will do it every time I wax now.

I'm not trying to turn this into a flame war over what wax is better though. Myself I use Meguiars NXT, I like it but I know everyone has their prefferences.

as for you living off a dusty gravel road I can sympathyze with you there. I too live of a dirt road and have a dirt driveway, and travel down many other dirt roads as well. Get yourself a California duster.They are great for quickly taking dust and pollen of the surface of your car.

if the wax is under the dirt you remove with the clay bar it will NOT remove wax. Which is why they were suggesting dish soap. Which is not the proper way to remove wax.

If things are that dirty, then claying twice in a spot will remove everything for sure.

but dish soap has abrasives in it. I was told to always use a car wash detergent for that reason.

Dish soap is really good at removing oils and a lot of waxes have oils in them. There is nothing bad about oil in the wax used on cars. Makes the wax go on easier and protect longer.
