Though the salt might stain the machine, it will not damage the washer acutely. Salt is an efficient way to get rid of stubborn stains.

Though it is cheap and common, it can also become a valuable cleaning agent for your laundry.

Here are some easy steps to use salt in your washing machine. 

#1. Automatic Washer

If you use an automatic washing machine, you will notice dedicated spaces for different detergents and cleaning agents.

Salt often serves as an alternative to cloth softeners, so locate the fabric softener compartment and pour in the salt.

Pour the ½ cup of salt into the detergent space and cover the compartment. Pour the salt according to the number of clothes you need to wash.

If the salt you added into the compartment is small, it will not have much effect.

Moreover, it would be best if you did not pour more than necessary, or you might need a lot of water to rinse your washer after doing your laundry.

#2. Manual Washer

If your washing machine is manual, it might not have a separate detergent compartment. As a result, you will have to add salt to your laundry manually.

To add the salt to the laundry, pour it into the washer tub after putting water and your laundry into the tub.

What Kind of Salt Do You Use for Laundry?

Common Salt, which is also known as Sodium Chloride (NaCl) or Table salt, is the best salt to use for your laundry.

Though you can use all types of salt for cooking, this does not work for washing. Salts like Epsom salts can harden your water.

Hard water limits the cleansing performance of the detergent on your laundry. The sulfate in the Epsom salts reacts with the calcium and hardens the water.

Though you can find some of these salts in your cleaning agents, it is often in refined and small quantities.

For instance, with ½ to 1 cup of table salt, you can keep the color of your clothes vibrant and remove odors and stains better from your clothes. 

Where Do You Put the Salt in a Washing Machine?

If your washer has a detergent or cloth softener compartment, you can pour the necessary salt into the detergent space.

Generally, you can find this compartment at the top of your washing machine, where you pour your detergent.

However, if your washer does not have a detergent compartment, you can manually pour the salt into the machine.

First, pour the water and laundry into the washer drum. Then, pour the amount of salt you need for the laundry into the mix and start the wash cycle. 

Salt has as many benefits in food as well as in your clothes. As ridiculous as that may sound, it is a fact.

Contrary to popular opinion, table salt does not stain or damage your clothes or cause your clothes to bleed during washing.

Here are some benefits of salts to your laundry:

#1. Restores the Yellowing Fabrics

Most fabric materials are prone to yellowing or fading when you expose them to harsh elements for a long time.

Stains from sweat and heat also give the same effect to your clothes, and the stains can be difficult to remove with only detergents. However, you can use salt to take care of these stubborn stains. 

Mix ¼ of baking soda and a spoon of salt and pour the mixture into a bucket of water. Soak the clothes in the water for 30 minutes before washing.

Instead of using Epsom salts for delicate materials like nylon, you can soak the clothes in a salt and water mixture for an hour.

Then, rinse the clothes in warm water and toss the clothes into your washer.

#2. Brightens Faded Curtains and Rugs

If your curtains are losing their shine or your rugs are fading, you can brighten them by washing them with salt.

However, this remedy is only effective on washable curtains and rugs. Mix four tablespoons of salt in a liter of water and use the mixture to scrub the curtains and rug.

#3. Keeps Fabrics From Fading

Some new fabrics and colored cotton clothes are prone to fading due to constant bleeding during laundry.

It could also ruin the color of other clothes in the drum, rendering them unwearable due to the clothes dye stains from the bleeding fabrics. 

However, you can put a stop to this with table salt. Before you wash the colored cotton fabrics, add ½ cup of salt to the machine.

You could also separate the colored clothes from other clothes before washing or washing the clothes together. 

How many salts Do I Put In My Washing Machine?

For an average amount of clothing, pour half a cup of salt into your washing machine.

Adding salt to your laundry helps remove tough stains and makes the color dye in your clothes less soluble.

In addition, the salt will keep the clothes from bleeding and eventually fade and ruin the color of other clothes. 

However, salt is more potent on natural clothes like cotton and wool. It has a lesser effect on synthetic fabrics like nylon and polyester.

While the machine is filling with water, you can add a spoonful of salt for each colored clothing in your laundry for more effect. You can double your salt input if the clothes are large.

Can You Wash Black Clothes With Salt?

You can wash black clothes with salt because it helps set and preserve the color of the cloth. In addition, it keeps the black dye on the clothes from fading and browning.

To wash your black clothes with salt:

  • Separate the black clothes from the fabrics with bright colors. Turn the clothes inside out to prevent the effect of friction between the clothes in the washer drum. 
  • Put the black clothes in the washing machine and add half a cup of salt to the washer drum. Pouring it directly will help retain the clothes’ dark color and eliminate detergent residues in the clothes.
  • For the wash cycle, avoid using a warm or hot water wash cycle to preserve the dark color of the clothes.
  • Use a dryer to dry the clothes or spread the clothes in a cool shady place to avoid the fading effect of direct sunlight on the clothes.
