Scrape soap and pour in about 1-2 tablespoons of white sugar, add a little clean water, stir to create a mixture that is very effective in repelling cockroaches and mice. Soak this mixture for about 10-15 minutes to dissolve all the soap bubbles, then place it where cockroaches and mice often appear. While white sugar attracts mice and cockroaches, soap is alkaline, and the organs of mice and cockroaches will be corroded, which can lead to their death.

In addition, you can use soap for many other purposes, such as:
Lubricating zippers
If the zipper is jammed, simply rub a bar of soap on the surface above the zipper. Then insert the key into the lock and open and close it a few times to make the zipper easier to use.
Eliminating shoe odors
Everyday shoes can easily develop unpleasant odors. You may not always be able to wash your shoes. To make your shoes smell fresh again, simply place a bar of soap in a tissue paper and wrap it up, then put it inside the shoes. Doing so not only effectively eliminates odors but also gives the shoes a light floral scent.
Reducing pain caused by new shoes
Many pairs of new shoes can be uncomfortable to wear. They may cause pain when you walk, but you don’t want to throw them away. A simple solution is to use soap to rub on the areas where the shoes rub against your skin. The inside of the shoes will become smooth, and your feet won’t be sore from rubbing.

Creating a pleasant scent in the wardrobe, preventing mold and insects
Due to the small and enclosed space, wardrobes can often have a musty smell when opened. Clothes can become damp and moldy, and sometimes even infested with insects. You can choose soap that contains natural plant essential oils and place it inside the wardrobe. This way, every time you open the wardrobe, you will smell a natural pleasant scent. Your clothes will also smell better and be protected from mold and insects.
Getting rid of annoying door squeaks
If your door makes a squeaking sound every time you open or close it, it can be very annoying. In this case, soap can be very helpful. Simply rub soap on the hinges of the door, then open and close the door a few times to effectively lubricate it.
