Oranj Peelz and Pro J are designed for drivetrains specifically. However, they can be used on other portions of the bike for stubborn grease and grime, but need to be rinsed well with water within 5-10 minutes of application to prevent damage. Pedro’s recently introduced two new solvent-free degreasers, Degreaser 13 and Pig Juice, which can safely be used on any material or finish and are better choice of degreasers for use on non-drivetrain parts. Green Fizz bike wash is also a great option for risk-free cleaning on any material. If Pro J or Oranj Peelz or Pro J comes into contact with non-drivetrain parts unintentionally, rinse well with water as soon as possible.
