#1 WD40 300134 Specialist Carb/Throttle Body and Parts Cleaner

To add to this, the cleaner comes in an aerosol can, which delivers the formula under high pressure.

As a result, the unwanted deposits will be blown off, thus leaving the surface clean. Moreover, this cleaning product can help you eliminate stubborn stains on different metal surfaces. Nonetheless, you have to ensure that the surface is not painted since the solvents in this formula are likely to react with the paint. In a nutshell, this formula can clean a wide range of mechanical parts as long as it is applied according to the manufacturer’s instructions.

Pros
  • Does not affect catalytic converters and O2 sensors
  • Will provide you with fast start-ups
