Cleaning an oven is one of those chores most people dread. Grease splatters, baked-on spills, and lingering odors can make it feel like a battle before you even begin. Many store-bought cleaners promise quick results but come with harsh chemicals, strong fumes, and endless scrubbing. Thankfully, there’s a simpler, gentler solution—often called “Nana’s trick”—that turns oven cleaning into an easy, low-stress task using items already in your kitchen.

This method requires just three things: a heatproof casserole dish, water, and a regular dishwashing pod. Start by preheating your oven to a low temperature, about 200°F (93°C). While it warms, fill the dish with water and drop in the pod. Once the oven is ready, place the dish on the middle rack, close the door, and let it heat for about an hour.

As the water warms, steam fills the oven while the pod slowly releases its cleaning agents. Together, they loosen grease and stubborn residue stuck to the walls, racks, and door—without harsh sprays or elbow grease. After an hour, turn off the oven and allow it to cool until safe to handle.

When you open the door, most of the grime will have softened. A damp cloth or sponge is usually enough to wipe everything clean. Tough spots may need a gentle scrub or a second steaming session. Always use oven-safe cookware and handle hot surfaces carefully.

What makes this trick so appealing is its simplicity and affordability. It saves time, avoids strong fumes, and keeps your oven cleaner with less effort. Sometimes, the easiest solutions really are the best.
