According to experts, salt can remove excess moisture in the air, therefore reducing the amount of condensation on your window.
Rock salt is highly effective for dehumidifying. Rock salt or NaCl is a hygroscopic material, meaning it both draws and stores water and works much like an electric humidifier. It's natural, non-toxic, cheap, easy to find, and easy to work with—not to mention, no electricity is needed!
Known to dehydrate and absorb moisture, salt is a cheap and effective way to reduce moisture caused by condensation. Using salt to tackle this watery residue on windows and doors can be done in several ways. Fill small pots with rock salt and leave them on your windowsill to draw out moisture.
Ways to Reduce Condensation in your Home

- Close Kitchen & Bathroom Doors. ...
- Dry Clothes Outdoors. ...
- Turn on Your Extractor Fan When Using Your Shower. ...
- Ensure Washing Machine Is Correctly Vented. ...
- Move Furniture Away from External Walls. ...
- Install an Extractor Fan.
To help with clearing the condensation away, you can make a simple, home-made solution by mixing two cups of water with two cups of white vinegar and a couple drops of washing up liquid. Pour this mixture into a spray bottle if you have one and spray the solution straight onto your window.
Rock salt naturally absorbs moisture out of the air, making it a great choice to use as a dehumidifier. To make a rock salt humidifier, you'll need a large bag of rock salt (also sometimes referred to as sodium chloride) and two 5-gallon buckets. You should be able to find both at a hardware store.
Rock Salt. Rock salt is a natural hygroscopic material that not only absorbs moisture, but also stores it — similarly to dehumidifiers. However, rock salt is completely natural, non-toxic and requires absolutely no electricity.
The easiest way to get rid of humidity is to get a flat container with an open top and fill it with a kilogram of coarse salt. Place it in your room and it should absorbed a lot of the excess moisture in the air. We recommend using a wider and larger container as it will allow for more exposure.
Salt itself is not a good conductor of heat but solution of salt in water conducts heat. Salt water is a good conductor because it is an ionic compound. When dissolved, it breaks up into ions. The ions are then good charge carriers, which is what electricity needs.
They dilute the water and hinder escape of water molecules into the air. The rate of return of water molecules to the liquid surface is proportional to their concentration in the gas, where there are no salt ions to interfere.
Baking soda can be used in many different ways at home. People use it to absorb water from the air, which makes the air less humid. Baking soda is a hygroscopic substance and it will absorb moist air.
If solving your moisture problem is something you'd like to do inexpensively, rock salt may be your answer. Because rock salt is hygroscopic it absorbs moisture from the air. If your plan is to get rid of the humidity in a damp basement, start with a 50-pound bag of sodium chloride to make your rock salt dehumidifier.
Silica packs or equivalent products can be placed in your closet to reduce humidity levels. These packs contain anhydrous calcium sulfate, which acts to absorb moisture from surrounding areas.
Using Uncooked Rice
Place the bags of rice in areas of the home that accumulate moisture. Leave each plastic bag open and placed out of reach of children and pets. The rice will absorb and trap excess moisture in the air, while using plastic bags will prevent the trapped moisture from leaking.
Add the amount of salt recommended by the manufacturer. Most manufacturers warn against using more than 1/8 teaspoon of salt. Some recommend starting with one or two pinches, then adding another pinch or two if the vapor is not sufficient.
Condensation occurs when warm air collides with cold surfaces, or when there's too much humidity in your home. This is especially common in winter, when your central heating system comes on in the cooler hours of the mornings and evenings.
Cold, thermally inefficient windows are a magnet for condensation. They'll likely become wet in the morning even if you try your best to ventilate your home throughout the day. That leaves you with one option – fixing the windows.
So opening the windows works and is an effective solution to condensation control.
Does Epsom Salt Absorb Moisture? What is this? Yes, it does. Magnesium sulfate, also known as Epsom salt, is a good absorber of moisture and is even used as a desiccant in its anhydrous form.
Let the baking soda sit on the carpet for several hours, up to 24 hours, to allow it ample time to soak up the remaining moisture and odor from the carpet.
The critical water content of sodium chloride (NaCl) is 0.5% at 74% relative humidity, which is the flow moisture point at which salt begins readily to absorb water vapor, and increases such that, at 75% relative humidity, the salt dissolves (hygroscopicity).
To prepare a saturate salt solution, the indicated salt is added to warm (about 40 °C) distilled water with stirring until no more salt dissolves. Additional salt is added to ensure an excess of the saturating salt. Table 2 provides approximate compostions for saturated solutions.
