Ensure the oven is turned off and completely cool.

Remove the oven racks and any other removable parts to clean separately.

In a bowl or container, mix Branch Basics All-Purpose Cleaner with warm water according to the product instructions.

Place the old rags in the mixture and ensure they are fully saturated. Let them soak for a few minutes to absorb the cleaner thoroughly.

Wring out excess liquid from the rags so they are damp but not dripping.

Lay the soaked rags over the grimy areas of the oven interior and door, making sure to cover all dirty spots. Use multiple rags if necessary to cover the entire surface.

Leave the rags on the oven surfaces for at least 30 minutes to an hour. This allows the cleaner to penetrate and loosen the grime.

After the soaking time, remove the rags. The grime should be softened and easier to remove.

Use a sponge or scrubber to wipe away the loosened grime. For tough spots, gently use the razor blade or scraper at a low angle to scrape off the stubborn grime without damaging the oven surface.

For any remaining stubborn stains, dampen the pumice stone and gently scrub the affected areas in a circular motion. Be careful to avoid scratching the glass or damaging the oven surface.

If needed, spray the interior of the oven with Branch Basics All-Purpose Cleaner to tackle any remaining residue. Let it sit for a few minutes before wiping clean with a damp cloth.

Wipe down the entire oven interior with a clean, damp cloth to remove any remaining cleaner and grime. Repeat as necessary until the oven is clean.

For a final touch, use a dry cloth or paper towel to dry and polish the surfaces to prevent streaks.

Soak the oven racks in a mixture of warm water and Branch Basics All-Purpose Cleaner for several hours or overnight.

Scrub the racks with a sponge or brush, rinse, and dry thoroughly before replacing them in the oven.

Ensure all surfaces are clean and free of residue. Replace the oven racks and any other removable parts.
