Wash your mouth with water. Place the centre of the tongue cleaner at the rear end of the tongue and scrape outwards. Scrape the tongue gently at least 3-5 times for complete removal of coats. Rinse your mouth and wash the tongue cleaner with warm water and let it dry.
Rub the tongue scraper with the lemon/lime, until tarnished areas are clean. Rinse and polish up with a clean, soft, dry cloth.
