You should buy one that has the following features:

  • Compound quality: The chemical composition of a cleaning agent is the most important factor. Cleaning agents are a mixture of different chemicals that thoroughly clean surfaces. It may be difficult to determine the exact chemical composition of a catalytic cleaner. However, you can rely on the feedback provided by previous users to make an informed decision.
