A car should be washed every week or every other week. At most, you should have it washed every month. Any longer than that and you might have to deal with detailing and maintenance nightmares such as bonded dirt unto the finish, scratches, hardened bug splatter, and so forth.
Other than that, it's pointless to wash a car that's merely dusty. The more sensible approach is to put down that garden hose and do some thorough detailing work on your vehicle instead. Otherwise, let the water freely flow and your KevianClean Car Wash Shampoo do the rest.
The Dangers of Excessive Car Bathing and Other Reminders
- Washing Every Day Is Not Ideal: Although it'd seem that washing your car every day is ideal, it actually isn't. There's a danger to be had when bathing your vehicle with tap water too often. Unless your washing water is drinking water or Perrier, mineral build-up can happen wherever hand-drying can't reach. Engine and solar heat can make these tap water minerals cling unto painted, plastic, and rubber surfaces. Trace salts can also corrode your car in areas you're unaware of.
- Save the Filthiest for Last: The car's lower body should be scrubbed and cleaned the last. The first thing you should wash is the upper body where the roof and glass windows are. Let the water stream down to the lower parts of your vehicle like falls. The dirty soap water should clean these parts initially before you go down and scrub them clean altogether. It's okay for a little dirt to go on them because these are the dirtiest, grittiest part of your vehicle with its constant contact with the ground.
- How to Clean Your Car's Lower Parts: Cleaning the legs and feet of your vehicle typically entails using a separate sponge or wash mitt to avoid cross-contamination, like brake dust ending up on your finish. Meanwhile, you should clean the sidewalls of your car with a firm plastic brush. Dealing with your gritty tires requires you to scrub deep with a brush because a wash mitt or a sponge won't cut it anymore.
- Stiff Bristles on the Lower Parts of Your Car: Unlike the upper portion of your car that has a smooth finish you don't want to scratch or mar, you can get away with using a plastic brush with stiff bristles in order to clean the dirt from places like your tires and tire sidewalls. The scratches produced on those areas won't be as noticeable as the scratches on your roof, fender, or doors for sure. Use a tire and wheel cleaner for good measure.
