Cooking oil is a staple ingredient in most households. It is used to fry, sauté, and even bake various dishes. But what happens to the oil after we are done using it? Is it safe to reuse it for cooking? These questions have sparked a debate among health-conscious individuals. On one hand, some say that reusing cooking oil can be harmful to one's health, while others claim that it can save money and reduce waste. In this article, we will delve deeper into the topic and explore the safety of reusing cooking oil and the different ways to clean it at home.

First and foremost, it is important to understand what happens to cooking oil when it is heated for prolonged periods. When oil reaches its smoke point, it starts to break down and release harmful compounds such as free radicals and acrolein. These compounds can have adverse effects on our health, including an increased risk of heart disease and cancer. Reusing cooking oil means exposing yourself to these harmful compounds repeatedly.

Moreover, when oil is heated multiple times, it becomes rancid due to the oxidation process. Rancid oil can cause digestive issues and lead to nutrient deficiencies. It also affects the taste and aroma of the food, making it less appetising.

Now that we know the potential health hazards of reusing cooking oil let's explore some effective ways to clean it at home.

Straining and Storing

The simplest way to clean cooking oil is to strain it before storing it. Once the oil has cooled down, pour it through a fine-mesh strainer or cheesecloth to remove any food particles or debris. This will prolong the shelf life of the oil and eliminate any burnt or unpleasant flavours.

Separating with an Egg

Another popular method for cleaning cooking oil is by using an egg. When an egg white is added to hot oil, it helps separate any impurities present in the oil. To use this method, whisk one egg white in a small bowl and slowly add it to the hot oil, stirring continuously. The egg white will bind with any food particles or impurities, making them easier to remove. Once the oil has cooled down, strain it through a fine-mesh strainer to remove the egg white and any impurities.


Refrigerating used cooking oil is another way to clean it and prolong its shelf life. When the oil is cooled, any impurities or food particles will solidify and can be easily removed by scooping them out with a spoon. This also helps to slow down the oxidation process and keep the oil from going rancid.


Similar to refrigerating, freezing used cooking oil can also help clean it. Pour the used oil into an ice cube tray and freeze it. Once the cubes are frozen, remove them from the tray and store them in a freezer-safe container. These oil cubes can be used for cooking in smaller quantities without the risk of exposing yourself to harmful compounds.

Filtering with Coffee Filters

If you want to completely remove any impurities from your used cooking oil, using coffee filters is an effective method. Take a clean coffee filter and place it over a jar or container. Slowly pour the used oil through the filter, allowing it to strain out any food particles or debris. This method may take some time, but it ensures that your oil is thoroughly cleaned.

Using a Fat Skimmer

A fat skimmer is a handy tool that can be used to remove excess fat or impurities from cooking oil. It works like a sieve and has a handle that can be extended and lowered into hot oil for easy removal of any debris or food particles. This method is quick and efficient, making it a popular choice among home cooks.
