Step 4 · Steam Clean Stair Treads
Start at the top of the stairs. Hold the steam cleaner nozzle a few inches above the carpet and press the trigger to release steam. Slowly move the nozzle backward along the tread, allowing the steam to penetrate the fibers. Release the trigger and pull the nozzle back towards you to suction up the loosened dirt and moisture. Work in small, manageable sections, ensuring each section receives adequate steam and suction. Overlap your strokes to ensure complete coverage.
