what acids and alkali are used to make an oven cleaner plz help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

To make an oven cleaner, various acids and alkalis can be used. The specific combination of chemicals may vary depending on the brand or recipe. However, two common ingredients used in oven cleaners are:

1. Acids:
- Sodium hydroxide (NaOH): Also known as caustic soda or lye, it is a strong base and an effective cleaning agent. Sodium hydroxide is commonly used to dissolve grease and other organic materials.
- Citric acid (C6H8O7): Derived from citrus fruits, citric acid is a weak organic acid. It helps to break down stubborn stains, soap scum, and mineral deposits.

2. Alkalis:
- Ammonia (NH3): A gaseous compound, ammonia dissolves grease, removes burnt-on food, and helps in loosening tough stains. It is commonly used in oven cleaners due to its strong cleaning properties.

When using any chemicals for cleaning, it is crucial to follow safety precautions. Wear protective gloves and eyewear, ensure proper ventilation, and carefully read and follow the instructions provided by the manufacturer.

Please note that combining different chemicals or using them inappropriately can lead to hazardous reactions or even produce toxic fumes. Therefore, it is recommended to purchase commercially available oven cleaners or consult expert resources for safe usage.
