Sodium chloride, commonly known as salt, has a variety of applications in and around our homes, not only for cooking but also for cleaning, maintenance, and improvement. 

This article offers a comprehensive compilation of various uses for salt, along with step-by-step instructions and relevant data to support each application. One of the first uses is the effective use of salt for eliminating ants in your home.

15 Household Uses for Salt

1. Eliminate Ants by Sprinkling Salt Around Your House

Using salt as a natural, chemical-free, and cost-effective solution for repelling ants is environmentally friendly and safe compared to commercial insecticides. Salt’s sodium content deters ants, and a study in the Journal of Economic Entomology found that sodium chloride effectively repelled various ant species, including Argentine ants and pavement ants.

To use salt for ant control:

Step 1: Identify where ants have been seen, focusing on openings, cracks, and crevices through which they may enter your home.

Step 2: Sprinkle a thin layer of salt around affected areas to create an ant-repelling barrier.

Step 3: Repeat the process as necessary to maintain an ant-free environment.

2. Absorb Moisture and Dehumidify

Salt is an excellent natural dehumidifier that can help absorb excess moisture in your home, preventing mold and mildew growth. A 2021 study published in Drying Technology found that salt effectively absorbs moisture from the air, making it an ideal dehumidifier.

To use salt as a dehumidifier:

Step 1: Fill a small, open container with salt (a jar or bowl will work well).

Step 2: Place the container in damp or high-humidity areas, such as basements or closets.

Step 3: Replace the salt regularly as it absorbs moisture and becomes saturated.

Salt can help remove stains, grease, and unpleasant odors from your sink. To use salt for cleaning your sink:
