Does a Fire Extinguisher Ruin an Oven? 2 Methods & Cleaning Tips

Does a Fire Extinguisher Ruin an Oven?

An oven fire is a common occurrence and a major worry for many homeowners, raising concerns about potential ruin to their appliances. It’s important to understand the role of fire extinguishers in such scenarios. Typically, a fire extinguisher is designed to put out a fire without causing damage to the oven, especially if it’s rated for home use. These extinguishers are effective against various types of fires, including those involving grease, oil, and combustible materials like fabric and paper.

When an oven fire is extinguished, it’s crucial to control and cool down the area. However, residues from dry chemical extinguishers or CO2 can be left behind, necessitating careful cleaning to avoid chemical exposure and potential damage. It’s essential to ensure that these residues are cleaned up promptly to prevent any long-term damage to the oven.

How Do You Clean a Gas Oven after a Fire Extinguisher?

After using a fire extinguisher on a gas oven, it’s imperative to clean up cooking grease, spilled food, and other remnants immediately. This not only helps in reviving the oven but also adheres to basic safety rules and prevents future fire situations. Cleaning and restoring the oven can seem daunting, but with the right methods, it’s quite manageable.

Method 1: Baking Soda & Vinegar Solution for Cleaning the Oven

A DIY method involving a baking soda and vinegar solution can be an effective and economical way to clean your oven after a fire. This method involves removing the racks and trays and using a brush or scraper to dust the interior of the oven. A solution of vinegar and water should be sprayed over the oven surface, followed by a baking soda paste applied to stained areas. This combination helps absorb grease and eliminates burnt smells. After applying the paste, it should be rinsed off with water, and the oven should be scrubbed clean. This method also includes cleaning the racks and trays separately, possibly in a dishwasher or with dishwashing soap and water.

Method 2: Using Commercial Oven Cleaners After a Fire

For those who prefer not to use a DIY solution, commercial oven cleaners are available in stores. These cleaners are often fume-free, which is important for health and safety. To use a commercial cleaner, first extinguish any fire and remove smoke, then let the oven cool. Remove the trays and racks and clean the surface of loose flakes. Apply the commercial cleaner to all sides and inside the oven, wipe it off after a short period, and repeat if necessary. This method also facilitates spot cleaning for caked-on spills and ensures that the racks and trays are cleaned effectively. After the cleaning process, the oven will be ready for use and restored to its original shine.
