RC Cars: Do-It-Yourself Help (Part 1)
Sometimes your car may act fancy. Like if you turn on your car, it keeps steering to one side. This may happen even if you keep the wheels straight.

A lot of dirt gets accumulated under the chassis and the most to get affected are the screw heads. To get clean and sparkling screw heads under the chassis, spray denatured alcohol on screw heads and then pick the dirt with the help of paper clip.

It is recommended to use denatured alcohol as it seems to work better than the simple green or motor cleaner.
