How to clean car interior

A clean car interior not only looks great, it is also better for your health and health of your passengers.
This 8-year old Acura in the photo belongs to a friend of mine; it has more than 140,000 miles on the odometer; yet with proper care its interior still looks very good, as you can see. It takes about an hour to clean the entire interior thoroughly. Be careful with water inside the car; if water gets into electrical components, it may cause problems. Similarly, don't soak the seats too much and don't let water to get under the carpet; it could cause corrosion, stains and damp mouldy smell. Make sure to dry the interior well after you done.

Remove the floor mats. Vacuum the seats and the carpet. Using the proper attachment, reach under the seats, around the pedals and the area between the front seats and the center console. Vacuum floor mats separately.

Use a soft brush attachment to vacuum the dashboard, center console and the doors. Be careful not to damage knobs, vents and sticking parts. Use the same attachment vacuuming the seats. Leather seats are very easy to damage, be careful no to scratch them with the vacuum hose.

Let's see how we can clean this dirty spot on the rear seat.

There are number of upholstery cleaning agents available. Here I used the Turtle Wax upholstery cleaner, but other products can work as well.
The first step, spray the cleaner evenly on the upholstery.

Rub vigorously. Once the dirty spot is gone, wipe it thoroughly with a dry soft cloth.

The dirty spot is gone. You can clean all the seats and door upholstery the same way, working one area at the time. If you don't have a special upholstery cleaner, a regular laundry detergent will work as well: Mix a small amount of the detergent with warm water. Dip a clean cloth into it. Squeeze out well - you want a barely moist cloth. Work harder on dirty areas. When finished, wipe out well with a clean, soft dry cloth.

Be careful with the leather-wrapped steering wheel and shifter knob as some of the leather care products can make them slippery or sticky. I personally don't use any products on my steering wheel and a shifter knob, I just clean them with clean and barely moist cotton towel. If you use any leather care products on your steering wheel, make sure that it is not slippery before you drive.

Vacuum leather seat crevices with the soft brush attachment - be careful, as the vacuum hose can easily scratch the leather.

Spray some leather cleaner agent on the soft clean cotton towel.

Wipe the seat gently, reaching into crevices and around the edges.
Here I used a two-in-one leather cleaner/conditioner. If you have just a cleaner, apply a conditioner later to protect the leather.
