The new oven smell, often described as a chemical or plastic-like odor, is primarily caused by a combination of factors related to the manufacturing and shipping processes of the oven. Here are the key reasons behind the new oven smell:

  1. Residual Chemicals from Manufacturing: During the manufacturing process, ovens and their components may come into contact with various chemicals, coatings, and adhesives. Some of these substances can emit odors when the oven is first heated.
  2. Protective Coatings and Packaging Materials: Manufacturers often apply protective coatings or use packaging materials to safeguard the oven’s surfaces during transportation and storage. These coatings and materials can release odorous compounds when exposed to high temperatures.
  3. Heat Elements and Insulation: Components like heating elements and insulation materials inside the oven can emit odors when they are heated for the first time. These odors may be a result of the materials used in their construction.
  4. Dust and Particles: Ovens can accumulate dust and particles during storage or shipping. When the oven is initially used and heated, these contaminants can burn off, leading to a noticeable odor.
  5. Natural Residue: In some cases, there may be natural residue or oils from the manufacturing process left behind on the oven’s interior surfaces. When the oven is heated for the first time, these residues can produce a distinct smell.
  6. Plastic Components: Certain plastic parts or components used in oven construction may release odors when subjected to high temperatures. This is especially true for ovens with plastic interiors.
  7. Adhesives and Sealants: Adhesives and sealants used in assembling the oven can emit volatile organic compounds (VOCs) when exposed to heat, contributing to the odor.

Why Does New Oven Smell Won’t Go Away?

When the new oven smell won’t go away, it can be frustrating, but there are several reasons why this may happen:

  1. Residual Chemicals: Some ovens are manufactured with coatings, adhesives, or insulation materials that can release chemicals or volatile organic compounds (VOCs) when exposed to heat for the first time. These chemicals can produce persistent odors.
  2. Inadequate Ventilation: Poor ventilation in the kitchen area can slow down the dissipation of odors. Without proper airflow, the smell may linger longer.
  3. Insufficient Use: If you haven’t used the oven much since you purchased it, the smell may persist because it hasn’t had the opportunity to burn off the initial residues and coatings from the manufacturing process.
  4. Residue Buildup: Over time, cooking spills and residues can accumulate inside the oven. These residues can mix with the new oven smell, making it more challenging to get rid of.
  5. Low-Quality Materials: In some cases, low-quality materials or poor manufacturing practices may lead to persistent odors that are difficult to eliminate.
  6. Hidden Residues: Odor-causing residues may be hiding in areas that are not easily accessible, such as between oven layers or behind panels.
  7. Underlying Issues: In rare cases, persistent odors may be a sign of a malfunction or problem with the oven’s components, like the heating element or insulation.

How To Get Rid Of New Oven Smells?

To get rid of the new oven smell, you can follow these steps:

  1. Ventilation: Ensure good ventilation in your kitchen by opening windows and doors, or by using exhaust fans. Proper airflow can help dissipate the odor more quickly.
  2. Burn-Off Cycle: Many ovens come with a burn-off cycle designed to remove the new oven smell. Consult your oven’s user manual for instructions on how to use this feature.
  3. Preheat and Ventilate: Preheat your oven to a low temperature (around 200°F or 93°C) and leave it on for an hour or two with the oven door open. This will help accelerate the process of getting rid of the smell. Make sure to monitor it during this time.
  4. Baking Soda: Place an open box of baking soda inside the oven. Baking soda is known for its odor-absorbing properties and can help neutralize the smell over time.
  5. Vinegar Cleaning: Wipe down the interior of the oven with a mixture of water and vinegar (equal parts) to help remove any residues left from the manufacturing process. Be sure to rinse thoroughly with water afterward.
  6. Activated Charcoal: Activated charcoal is excellent at absorbing odors. You can place a bowl of activated charcoal inside the oven and leave it there for a few days.
  7. Regular Cooking: Use the oven regularly for cooking. The more you use it, the faster the smell should dissipate. The heat from cooking can help eliminate residual odors.
  8. Cleaning: Keep the oven clean and free of food spills or residues. Regular cleaning will prevent odors from lingering.
  9. Patience: Sometimes, it just takes time for the new oven smell to completely disappear. Be patient and continue with the steps mentioned above.
  10. Contact the Manufacturer: If the smell persists despite trying these methods, and especially if it is accompanied by unusual odors or smoke, consider contacting the oven manufacturer’s customer service for further advice. There might be an issue with the appliance that needs attention.

Can You Cook Immediately After Getting a New Oven?

Cooking in a new oven immediately after getting it is generally safe, but there are a few precautions and considerations to keep in mind:

  1. Read the User Manual: Before using your new oven, it’s essential to read the user manual that comes with it. The manual will provide specific instructions and safety guidelines for your particular oven model. It may also include recommendations regarding initial use.
  2. Burn-Off Cycle: Some oven manuals recommend running a “burn-off” or “preheat” cycle before using it for cooking. This cycle is designed to burn off any residues from the manufacturing process and reduce the new oven smell. Follow the manufacturer’s instructions for this cycle if it’s recommended.
  3. Ventilation: Ensure that your kitchen is well-ventilated when using a new oven for the first time. Open windows and doors or use exhaust fans to help dissipate any odors or fumes that may be produced during the initial heating.
  4. Odor and Smoke: It’s normal to experience some unusual smells and perhaps even a little bit of smoke when using a new oven for the first time. This is often due to the burning off of residues or coatings from the manufacturing process. These odors and smoke should dissipate after the initial use or after running a burn-off cycle.
  5. Test Run: You can perform a test run by heating the oven to a moderate temperature (e.g., 350°F or 175°C) for a short period without any food inside. This can help further burn off any remaining residues and ensure that the oven is working correctly.
  6. Clean the Interior: Before cooking food, it’s a good practice to clean the oven’s interior to remove any dust or debris that may have accumulated during storage and shipping.
  7. Monitor Carefully: While using your new oven for the first few times, keep a close eye on it to ensure that it operates as expected and that there are no unusual odors, smoke, or issues.
  8. Patience: If you notice any lingering odors or unusual smells during the first few uses, don’t be alarmed. It’s normal for some ovens to have a “new oven smell” initially. This should gradually dissipate with regular use and proper ventilation.
