Mr. Muscle is determined to free the world from dirt. That's why he developed Mr. Muscle Cera-fix specifically to clean, protect, and shine glass-ceramic cooktops. The special formulation creates a protective film on the surface that maintains the natural shine of your cooktop. With special burn-in protection, it prevents the hard burning of overcooked foods, makes daily cleaning easier, and protects against damage caused by the overflow of heavily sugary foods.
