Brilio.net – Bringing home-made chili sauce is always successful in increasing our appetite for lunch at work or school. The problem only emerged when the lunch box was washed, it turned out that the spicy smell was strong and the oil was still firmly attached even though it had been scrubbed with soap many times.

The residual smell of onion chili sauce or shrimp paste that remains will certainly make us uncomfortable if we want to use the container to store fruit or other food. Fortunately, we can use a few simple kitchen ingredients at home to restore the freshness of our favorite plastic lunch box without damaging the material.

Why does plastic absorb odors and chili oil so easily?

Plastic has a unique surface structure because it consists of microscopic pores or porous polymers. The basic nature of most plastic containers is lipophilic, which means they really like to bind to oil. When we add oily and warm chili sauce, the pores of the plastic will expand so that the spicy aroma molecules and capsaicin from the chili are trapped inside. That’s the reason why ordinary dish washing soap often only cleans the oil on the surface, but fails to remove the odor that has been locked in the pores.

The Best Kitchen Ingredients to Neutralize Strong Aromas

We can choose some of the ingredients below that are easiest to find in the home kitchen to help remove stubborn odors:

Choice of Tricks to Clean the Smell of Chili Sauce in Plastic Containers

Here are several practical steps that you can try right at home to deal with the smell of chili sauce in plastic containers:

Hack 1: Baking Soda Paste Method

Baking soda is known as a natural ingredient that is very effective at neutralizing acid and absorbing unpleasant aromas. This ingredient works by opening the bonds of chili oil molecules that are trapped in the pores of the plastic. You don’t need to worry because this method is very safe and will not erode the surface of the lunch box.

Material:

– 2 tablespoons baking soda
– A little warm water

Step:

1. Mix baking soda powder with a little warm water in a small bowl until the texture turns into a thick paste.
2. Spread the paste evenly over the entire surface of the plastic container that smells of chili sauce.
3. Leave the container for 1 to 2 hours so that the baking soda content works optimally to absorb the odor, then rinse with warm water until clean.

Hack 2: Coffee Grounds Trap Method

Coffee grounds have strong aromatic compounds that are able to bind and cover the remaining stubborn chili odor. The dry nature of coffee grounds also helps attract moisture left over from washing which often triggers musty odor-causing bacteria. This trick is very suitable for plastic containers that are dry but still have a strong aroma.

Material:

– 2 tablespoons of pure coffee powder without sugar

Step:

1. Make sure the plastic container to be cleaned is dry after washing it with soap.
2. Put dry coffee grounds into the container, then close the lid of the lunch box tightly.
3. Leave the container closed overnight so that the coffee grounds trap all the aroma of the chili sauce, then discard the coffee and lightly wash the container the next day.

Hack 3: Lemon Water and UV Light Soaking Method

The natural citric acid content in lemons is very effective in breaking down the components of chili oil while also killing germs. The combination of lemon juice and exposure to direct sunlight will trigger a natural reaction that fades yellow stains while eliminating odors. This method is the freshest solution because it leaves a natural orange aroma in your lunch box.

Material:

– 1 fresh lemon
– Enough warm water

Step:

1. Cut a lemon in half, then rub the pulp directly onto the inside wall of a stained and smelly plastic container.
2. Squeeze the remaining lemon and add a little warm water to the container until it is half full.
3. Dry the plastic container under direct sunlight for several hours until the liquid evaporates, then wash it as usual.

Tips to Prevent Chili Smell from Sticking to Plastic Containers

– Get into the habit of rinsing the container with cold water first if the remaining chili sauce is still oily, don’t use hot water straight away because hot water can actually open the pores of the plastic and lock in the smell.
– Line a plastic container with plastic wrap or banana leaves if you want to bring very oily chili sauce so that the liquid doesn’t come into direct contact with the plastic walls.

FAQs

Are used newspapers really safe to use to absorb odors in food containers?

The carbon in newspaper ink is effective in absorbing odors, but for food containers, you should put a barrier such as thick kitchen tissue on the inside of the container first. This aims to prevent newspaper ink residue from sticking directly to the plastic surface which will later come into contact with our food.

Why are thin plastic containers more difficult to deodorize than thick ones?

Thinner plastics usually have a lower polymer density. This makes the pores tend to be looser and more easily absorb oil molecules and chili color pigments more deeply, so it requires a longer soaking time to remove the smell.

Can activated charcoal be used to remove the smell of chili sauce in lunch boxes?

Very well, activated charcoal has an extraordinary high absorption capacity for gaseous or volatile odor molecules. You simply wrap a small lump of activated charcoal in a thin cloth, place it in a dry lunch box, then close it tightly for several hours until the aroma is neutral again.

Is table vinegar safe if used to soak plastic containers for a long time?

Table vinegar is very safe for cleaning plastic, but you should not soak it for more than 3 hours. It is feared that the acidic nature of vinegar is too concentrated, which can make certain types of plastic become a little stiff or cause surface discoloration if exposed for too long.

How do you ensure that the chili smell has completely disappeared before storing the container in the cupboard?

You can test it by pouring a little warm water into an empty container that has been cleaned, then cover it for 5 minutes. After that, open the lid and breathe in the warm steam; If there is no remaining spicy aroma evaporating, it means your plastic container is completely clean and ready to be stored.
