Cleaning an oven is a chore many put off, but Nana’s simple trick makes it easy and low-effort using three common items: a dishwashing pod, a heatproof casserole dish, and water.

Start by preheating the oven to 200°F (93°C). Fill the casserole dish with water, add a dishwashing pod, and place it on the middle rack. Leave the oven on for about an hour, allowing steam to form as the pod releases enzymes that loosen grease and baked-on residue.Once cooled slightly, wipe down the walls, door, and racks with a damp cloth—most grime should lift with minimal effort. For stubborn spots, repeat the steaming process or gently scrub with a soft brush, avoiding abrasive tools on glass or coated surfaces.This method reduces harsh chemical smells, making it ideal for homes with kids or pets, and it’s cost-effective since the items are already common in most kitchens.Using this trick monthly helps prevent grease buildup, supporting better oven performance. Nana’s method proves that letting heat and steam do the work saves time and keeps your kitchen fresh with ease.
