Understanding what are the ingredients in the salt trick is key to unlocking its full potential, whether you are tackling tough stains, deodorizing carpets, or polishing tarnished metals.

Quick Summary

The salt trick is less a single recipe and more a collection of powerful, natural cleaning formulas that leverage salt’s physical and chemical properties. By combining salt with other household staples, you can create effective, non-toxic cleaners for a variety of tasks. The specific ingredients depend on the surface you are cleaning and the type of stain you are treating.

The Core Ingredients in the Salt Trick

Salt: The Versatile Abrasive and Absorbent

At its core, the salt trick relies on the common mineral sodium chloride. Salt’s grainy texture makes it an excellent, gentle abrasive for scrubbing surfaces without causing scratches. As an absorbent, it can effectively pull moisture and pigments from spills, making it invaluable for treating fresh stains. Different types of salt can be used, but coarse sea salt or kosher salt is often preferred for scrubbing due to its larger crystals, while fine table salt works best for absorbing spills quickly.

Vinegar: The Powerful Acid

White vinegar is a highly effective companion to salt, particularly for tasks that require breaking down mineral deposits, rust, or greasy grime. The acetic acid in vinegar reacts with many types of stains and build-up, and its synergy with salt creates a potent cleaning paste or solution. This combination is especially effective for cleaning and disinfecting surfaces like drains, countertops, and even toilets.

Baking Soda: The Deodorizing Alkali

Baking soda, or sodium bicarbonate, is another key player in the salt trick. It works as a deodorizer, a mild abrasive, and a grime-buster, particularly when paired with salt. Mixing baking soda with salt creates a powerful scouring powder. When baking soda and vinegar are combined, they create a fizzing reaction that helps lift dirt and break down grease. This makes it ideal for cleaning ovens, stovetops, and deodorizing carpets.

Lemon Juice: The Natural Bleach and Deodorizer

Lemon juice provides a citric acid boost that works as a natural bleach and disinfectant. Paired with salt, it creates a paste that can whiten and freshen surfaces. This is a classic combination for brightening wooden cutting boards and polishing copper or brass. The lemon also leaves a fresh, clean scent, making it a pleasant alternative to harsh chemical cleaners.

Other Common Ingredients

Depending on the specific task, other items can be added to the salt trick formula:

Club Soda: The carbonation in club soda can help lift fresh stains, like red wine, when combined with salt.
Essential Oils: Adding a few drops of essential oil, like lavender or lemon, can provide a natural fragrance and additional antimicrobial properties to your cleaning solution.
Flour: A paste made from salt, flour, and vinegar can be used for polishing heavily tarnished copper, as the flour helps thicken the mixture and hold it in place.

Combining Ingredients for Specific Cleaning Tasks

Salt Trick for Carpet Stains and Odors

For fresh carpet spills, particularly red wine, the salt trick is a lifesaver. Immediately blot the spill to remove excess liquid. Generously cover the remaining damp stain with table salt. The salt will absorb the moisture and pull the stain upwards. Let it sit for at least 30 minutes, or overnight for a deep-set stain. Vacuum the dried salt away. For older stains or deodorizing, a mixture of equal parts salt and baking soda can be sprinkled on the carpet, left for an hour, and then vacuumed up.

Salt Trick for Polishing Metals

To restore the shine to tarnished copper or brass, a simple paste works wonders. Combine equal parts salt and flour, then add enough white vinegar or lemon juice to create a thick paste. Apply the paste to the metal surface with a soft cloth, let it sit for about an hour, and then buff with a clean cloth. The acid from the vinegar or lemon lifts the tarnish, while the salt acts as a mild abrasive to remove grime.

Salt Trick for Clogged Drains

For a slow-draining sink, a simple and eco-friendly salt trick can help. Combine half a cup of baking soda with half a cup of table salt and pour the mixture down the drain. Let it sit for 10-20 minutes, then flush the drain with a kettle of boiling water. The salt and baking soda work to break down grease and buildup, while the hot water rinses it away. This method is a great preventative measure but is not a replacement for professional plumbing if you have a significant blockage.
