A vibration method of in situation cleaning of SCR catalyst units is disclosed. The system may include a hood that is designed to be manually positioned above the catalyst and pneumatic vibrators to be manually positioned under the catalyst layers to be used in concert with each other to manually clear the catalyst of built-up particle ash. The hood configuration blows and vacuums the ash from the top of the catalyst while the vibrators shake to ash loose from within the catalyst from the bottom of the catalyst modules.
