Firstly, oven cleaners are toxic, so even if you use them correctly, they can cause harm to you. If you’re pregnant or breastfeeding, don’t use them near your face or in your eyes. Use oven cleaner with gloves. After using the oven cleaner, wash your hands thoroughly if you didn’t wear gloves.
As a second step, you should not inhale the fumes from the oven cleaner. Instead, it would help if you splashed some on the surface, then scrub it with a stiff brush. Keep doing this until the liquid’s all gone.

What happens if you leave the oven cleaner on for too long
When leaving oven cleaner on a stove or range, you should remove it immediately. The residue can burn off and disappear if you do it right away. Secondly, make sure you don’t get any residue on the rest of your stove. If there’s residue on other parts of the stove, use an old toothbrush and brush it off.
Don’t use too much pressure when you brush the residue off your stove. You don’t want to scratch or damage the surface of your stove. Also, make sure that you don’t use a metal utensil to scrape off the residue. A wooden spoon or a plastic fork will be fine.
After that, just clean the area with a rag dipped in water. Put a paper towel on the rag to absorb the excess water. If you are ready to use your stove, let the area air dry before using it.

How to use an oven cleaner?
Using an oven cleaner can help you effectively clean the interior of your oven. Here’s a general guide on how to use an oven cleaner:
Steps to Use Oven Cleaner:
- Read the Instructions: Carefully read and follow the instructions provided on the oven cleaner product label. Different brands and types of oven cleaners may have specific usage guidelines.
- Preheat the Oven (Optional): Some oven cleaners work more effectively when the oven is slightly warm. Check the product instructions to see if preheating is recommended.
- Protect Surrounding Areas: Use old newspapers, paper towels, or aluminum foil to protect the floor and surrounding surfaces from any potential drips or spills.
- Apply the Cleaner: a. Shake the can or bottle of oven cleaner well before use. b. Spray or spread the oven cleaner evenly over the interior surfaces of the oven, focusing on areas with heavy grease and grime buildup. Avoid getting the cleaner on heating elements or other sensitive components. c. For stubborn stains or baked-on residue, you may need to apply a slightly thicker layer of cleaner.
- Let the Cleaner Sit: Close the oven door and allow the oven cleaner to sit for the recommended duration, typically around 15-30 minutes. This allows the cleaner to penetrate and loosen the grease and grime.
- Scrub and Wipe: a. After the recommended waiting time, use a non-abrasive scrubbing pad or a designated oven-cleaning brush to scrub away the loosened dirt and residue. Work gently to avoid scratching the oven surfaces. b. Wipe away the cleaner and loosened the grime using damp paper towels or a cloth. You may need to repeat the scrubbing and wiping process for heavily soiled areas.
- Rinse and Dry: Once the interior is clean, dampen a clean cloth with water and wipe down the oven interior to remove any remaining cleaner residue. Then, use a dry cloth to thoroughly dry the surfaces.
Is it safe to leave oven cleaner on overnight?
Many people are worried about leaving something like oven cleaner on their stove overnight. They are afraid that it will get away from them and damage the place where it was left. This is not true. At least, it is not true if you use the right amount of oven cleaner.
Oven cleaners contain a chemical known as “ammonia.” When this chemical comes in contact with an acidic substance such as sour milk, yogurt, or vinegar, it changes into a harmless gas called “hydrogen chloride.”
So, what happens is that when the hydrogen chloride comes in contact with the non-acidic substance of your stove, it turns it into a harmless gas that can then safely be vented out through your stove’s ventilation system. Therefore, it is perfectly safe to leave oven cleaner on your stove overnight.
