I am Brian Sandall and I am an enthusiastic car enthusiast. My cars tend to be kept as clean as possible. I use only the latest techniques I find on the Internet. In fact, I rarely drive while it is raining!
Here is a fundamental car care procedure you can follow. It's simple and affordable, but will require about thirty minutes weekly. It's important to clean your car 2 times every 7 days. if you must clean your car or truck in the rain, function it. There's nothing wrong with using a community, tunnel-style carwash. What ever it requires to maintain your vehicle consistently clean, just do it.
Next, clean down your dash and vacuum your interior on every other carwash. Like the dirt on your paint, frequent wipe downs of your dash, console, grills, car seats, etc., prevent the long-term build up of soil.
Every fourth carwash, that is every 2 weeks, perform a spot wash of your floor coverings and floor mats. It's really simple to do if you undertake this frequently. Purchase carpet shampoo and rigid carpet brushes from an automotive retailer. Brand isn't crucial. Now brush your carpets and floormats, next vacuum carefully. Then vacuum. Apply the shampoo fluid on mats and carpets. Don't use too much, as it will leave a smell and be hard to remove. Scrub into a froth. Extract the foam. Now grab a small number of bath towels. Scrub the freshly shampooed carpets with your rags.
Once every two weeks, clean your windows. Use a clean microfiber towel and a glass cleaner specific for automotive windows. Look at your windows from multiple angles as you work, preferably in direct sun. But be diligent and consisten about cleaning your windows. Don't assume that your interior windows will stay clean for long. The glues used to assemble your car evaporate over time and fog up your windows perpetually. The more frequently you clean your windows, the better visibility you will have in every direction.
Finally, use a concentrated acid-based wheel cleaner from Meguiars called Wheel Brightener. The right wheel cleaner applied as often as twice a week prevents the long term discoloration of your wheels. If you are consistent about washing your car twice weekly, you will have so little dirt and brake dust on your wheels that you can simply wet your wheels, then spray Wheel Brightener, then wet them again to get them fully clean again.
