Few people know that banana peels – something seemingly useless – actually have many amazing uses in daily life, especially when combined with laundry detergent.
Banana peels are often thrown away after eating, but this so-called “waste” still contains many benefits. In particular, banana peel mixed with laundry detergent has a variety of uses that will surely surprise you.

What are the benefits of mixing banana peel with laundry detergent?

Below are the specific effects of this mixture and how to use it effectively in everyday life.

Repelling cockroaches

Cockroaches are common household pests that carry bacteria and pathogens harmful to health. Killing cockroaches by hitting them with slippers, as many people do, can spread bacteria throughout the home. A safer and more effective method is to use banana peels mixed with laundry detergent.

How to do it:
Cut the banana peel into small pieces, place them in a container, add a little salt and laundry detergent, then stir the mixture with chopsticks. The natural scent of the banana peel attracts cockroaches, while the salt and detergent dehydrate and block their respiration, leading to their death.

Place this mixture where cockroaches often appear at night, and you will see clear results the next morning. This method is not only safe but also helps keep your living space clean and hygienic.

Other Uses of Banana Peels

1. Cleaning leather shoes

Over time, leather shoes can become dull and covered in dust. Banana peels contain pectin, a substance that cleans and polishes leather surfaces. Simply rub the inside of the peel over your shoes; then wipe with a soft cloth to restore shine.

2. Eliminating odors in cars

New cars often have unpleasant odors, especially from leather seats. Banana peel contains natural acids and antioxidants that help neutralize odors.

Method: Place a few banana peels in the car overnight. The chemicals in the peel will help absorb the unpleasant smell. Replace the peels regularly to avoid rotting.

3. Fertilizing plants

Banana peels are a natural source of nutrients and can be used as fermented fertilizer.

Instructions:
Tear the peel into small pieces, put them in a bowl with water, and cover with plastic wrap. After 3–4 days of fermentation, strain the liquid, dilute with water (1:1 ratio), and use to water plants. This banana peel “tea” helps plants grow strong and bloom better.

4. Ripening fruit

Banana peels release ethylene, a natural ripening agent.

How to use: Put the peel together with unripe fruit in a sealed bag. After 2–3 days, the fruit will ripen faster.

5. Reducing effects of alcohol

To make a natural hangover drink, boil chopped banana peel with a bit of sugar for 7–8 minutes, then strain the liquid. This helps reduce dehydration and discomfort after drinking alcohol.
