Professional Car Washes: Effect on Wax Longevity?
These days it's a lot more convenient for me to take my car to a car wash, rather than washing it myself. Doing that saves my back, so that I can still wax the car by hand, which I enjoy.
Here in California, we have a lot of "hand" car washes, that is, the cars are put on a traditional car wash conveyor, with soap and water showering down on the car, but typically two men then wash the car using soapy hand mitts.
I typically wash my car (dark colored metallic German paint) about every ten days to two weeks, using Instant Detailer and FX Spray Wax in between washes. The wax on my car is two coats of Carnauba wax. My car is garaged at night and in shade much of the day.
My question is: does the wax used in professional car washes tend to strip wax faster than a Mother's or Mequiar's type car wash shampoo? How many weeks or car washes should my wax job be able to sustain before it is time to wax again?
Any suggestions for making the wax job last longer? I would be willing to try the Reflections Wax, assuming it has some of the soft look of caranuaba.
Oh yes, one more thing. Does getting the "Polish Foam Wax" at the car wash aid in adding any temporary protection? While not a substitute for hand applied wax, it certainly does a lot to add shine!
Thanks in advance.
