Catalyst Maintenance Services

GCS offers catalyst replacement and chemical washing for all makes and models of catalysts and substrates. Maintenance service must be performed at regular intervals to keep your catalyst elements in compliance with emissions regulations.

Catalyst Washing

Catalyst washing is the chemical process for removing accumulated ash from the surface of the catalyst. This process significantly extends service life. Typically chemical wash is performed when CO (carbon monoxide) reduction efficiency is reduced from 80% to 65%. Generally, 2 stroke engines require more frequent washing than 4 stroke. High speed 4 stroke engines should be clean no more than twice; 2 stroke or slow speed, clean maximum four (4) times. If a catalyst has been previously cleaned, it will not return to its full capabilities. As a rule, catalysts should only be cleaned three (3) times before needing to be replaced; each cleaning removes some of the precious materials required for the catalytic process.
