Do not swallow. Do not place powder in mouth. Keep solution away from metal surfaces. 1. Stir 1/4 capful of Steradent Powder into water as hot as the finger can bear (40-50°C), using just enough water to cover the dentures. Do not use boiling water. Brush & rinse dentures with water to remove any large food debris. Place denture in solution. 2. For the removal of light stains leave for up to 10 minutes. Ensure dentures with metal parts are not soaked for longer than 10 mins. Heavier stains may need up to 20 minutes. For more stubborn stains, try regular overnight soaking. Do not use in conjunction with any other denture cleaner. 3. Brush lightly and rinse thoroughly before replacing in mouth.
