Nothing is more frustrating than having completed a stain removal procedure on a garment only to find a fresh grease stain from a dirty stain removal board.
Setting up a daily cleaning schedule can prevent such unpleasant surprises. Make it a habit at the end of the day to wipe down all the stain removal bottles with a damp cloth. Since dust, dirt, and grease tend to build up on the under side of the board and pipe work, also wipe the surface of the board, the under side of the board, and all pipe work and hoses. Remove the screen located at the nose of the board and wipe it down with a damp cloth or flush it with the steam gun. Clean the stain removal brushes by flushing them with steam, drying them with the air gun, and placing them bristle-side down on the hard surface of the stain removal board.
Once a week, give the stain removal board a good general cleaning. This includes removing the fabric tray cover and washing it. Remove all screens and the hard surface and wipe any debris away from the drain holes. Pour approximately one cup of warm, soapy water into the vacuum ring while holding down the vacuum pedal. Release the vacuum pedal and the water will run into the drain receptacle.
This will flush out any obstructions in the vacuum line. Repeat this procedure for the smaller, sleeve stain removal board. Empty the water that has collected in the drain receptacle into a hazardous waste container.
