How to Clean Oven Inside: Step-by-Step Guide for a Spotless Oven

A dirty oven isn't just an eyesore — it can affect the taste of your food and even become a fire hazard. Whether you're dealing with baked-on grease or stubborn burnt residue, cleaning the inside of your oven is easier than you think. This guide walks you through the most effective methods, from natural DIY solutions to commercial cleaners.

Why Cleaning Your Oven Inside Matters

Over time, food spills and grease accumulate on oven walls, the bottom, and the door. When heated, these residues burn and produce smoke, unpleasant odors, and can even affect cooking performance. Regular cleaning — ideally every 3 months — keeps your oven running efficiently and your food tasting its best.

What You'll Need

• Baking soda
• White vinegar
• Dish soap
• Rubber gloves
• A non-scratch scrub sponge
• Microfiber cloths
• A spray bottle
• Optional: commercial oven cleaner or degreaser

Method 1: Baking Soda and Vinegar (Natural, Chemical-Free)

This is the most popular DIY method — safe, effective, and uses ingredients you already have at home.

Step 1: Remove the oven racks

Take out all racks and set them aside to clean separately.

Step 2: Make a baking soda paste

Mix ½ cup of baking soda with a few tablespoons of water until you get a spreadable paste. For best results, use a quality baking soda like Nutricost Baking Soda (2 LBS) — it's food-grade and works great for cleaning too.

Step 3: Coat the oven interior

Spread the paste over all interior surfaces, avoiding the heating elements. Pay extra attention to heavily soiled areas. Let it sit for at least 12 hours or overnight.

Step 4: Wipe it down

Use a damp non-scratch scrub sponge to scrub away the paste and loosened grime. Wipe clean with a damp microfiber cloth.

Step 5: Spray with vinegar

Fill a spray bottle with white vinegar and spritz any remaining baking soda residue — it will foam up and help lift the last bits of grime. Wipe clean.

Method 2: Commercial Degreaser (Faster Results)

For heavily soiled ovens, a commercial kitchen degreaser cuts through grease much faster. Lysol Pro Kitchen Spray Cleaner and Degreaser is an antibacterial formula that works on ovens and appliances — just spray, wait 5 minutes, and wipe clean with a microfiber cloth.

Always ensure the oven is completely cool before applying any cleaner, and ventilate the kitchen well.

Method 3: Steam Cleaning

A handheld steam cleaner is a powerful, chemical-free option. The pressurized steam loosens baked-on grease and food without scrubbing. Simply direct the steam nozzle at soiled areas, then wipe away with a microfiber cloth.

Tips for Maintaining a Clean Oven

• Place a silicone oven liner or baking sheet on the bottom rack to catch drips.
• Wipe up spills as soon as the oven cools after each use.
• Clean your oven every 3 months, or more often if you cook frequently.
• Run the self-cleaning cycle (if available) only 2-3 times per year to protect the oven's enamel.
