My husband thinks one of the best modern laundry inventions are laundry scent boosters.

He loves getting a shirt out of his drawer several weeks after it’s been sitting in there, putting it on, and breathing in that clean, freshly washed scent.

But those fresh scents come with a price.

A hefty one at that. That stuff costs 20¢ an ounce (which is also the smallest amount they suggest you use in a load).

With my laundry detergent, I try to spend less than 10¢ a load. And that actually cleans my clothes. I am not going to spend double that amount to make it smell fresh.

(And if I’m being completely honest, they also come with a slew of harsh chemicals that I really prefer not to use.)

Let me show you how to spend a fraction of that cost and get the same awesome, extra, freshness you’re hubby will love too.

Ingredients & Supplies:

Here are the supplies and ingredients you’ll need to make homemade laundry scent booster:

  • 2 Cups Coarse Kosher Salt (NOT the same as Epsom Salt, and they work differently as noted below)
  • 20 Drops Lemon Essential Oil (I use Young Living Oils because of their purity promise)
    OR you could use a Fragrance Oil (they are less expensive and the scent will last longer)
  • Glass or Plastic container or jar for storage = FREE

I repurposed a pickle jar with a pretty chalkboard sticker on the front for my laundry scent booster.

You cannot use regular granulated table salt for this recipe. It has to be a course salt that looks like crystals. (More details on this below.)

First, grab your jar and add 1 cup of the salt to the jar. I use a piece of paper to “funnel” it into the jar as I pour it out of the measuring cup. Easy Peasy!

Add 10 drops of your lemon oil to the salt.

Mix it to thoroughly combine. I like to use a fork to combine the salts and oils together in the jar. They mix together in seconds.

You just want to make sure the oils are incorporated all the way through all the salt.

Then, add the other 1 cup of the salt to the jar and essential oils and repeat the mixing process.

That’s it. You’re done.

You’ve got your very own laundry scent booster ready to freshen up your towels and clothes.

How To Make It Smell So Good

Besides adding in essential oils or fragrance oils to make sure it smells good before it hits the water in your washer. Here’s the secret to making sure your laundry scent booster actually works, when it doesn’t have artificial scent boosters inside it.


Wait, what??

Yep, time. You just need to let it meld for a few minutes (approximately 10-20 minutes) before you throw it in the washer.

If you make it up the night before, then you’re golden. It’s not gonna smell more the longer you let it sit. After 20 minutes that as smell-saturated as those salt crystals are gonna get.

But let the meld happen and you’ll be a happy smelling camper when you pull a new towel out of the closet.

Why This Works To Freshen Laundry

I was skeptical at first that this easy recipe would truly work.

Then I went to Walmart and looked at all the laundry scent boosters.

None of them have the ingredients listed. Some look like mini colored chocolate chip discs.

But the majority of them look like course salt crystals.

Upon researching using salt in laundry, I found that salt really acts as a softener (although upon testing that theory, it’s not quite as good as this recipe).

Course salt is the perfect ingredient as a laundry scent booster because it takes longer to dissolve, therefore the scent stays in the washer with the clothes longer making them have a stronger fresh smell long after the water has washed down the drain.

Epsom Salt & Kosher Salt Are Not The Same

All over the internet you’ll find recipes for homemade fabric softener crystals using Epsom salt instead of salt.

IMPORTANT: Epson Salt & Kosher Salt are NOT interchangeable. Especially when dealing with your laundry.

A lot of well-meaning people seem to think that Epsom salt is just another type of salt, like Himalayan pink salt. It’s not!

Scientifically, kosher salt is actually sodium chloride (NaCl) and Epsom salt is magnesium sulfate.

Hard water is essentially caused by two minerals: calcium and magnesium. So by adding Epsom salt to your laundry you are also adding in more magnesium therefore making your hard water actually harder.

Hard water causes your laundry soap to be less effective. It fades colors faster and causes fabric to feel rough and scratchy.

Don’t get me wrong, we keep Epsom salt on hand for lots of things like Mandarin Orange Bath Salts to soak in a hot tub after a long night of sports.

But Epsom salt needs to stay in the bathroom, while your Kosher Salt can be used in the kitchen and for your laundry.

What Does It Cost?

  • 2 Cups Coarse Kosher Salt = 81¢
  • 20 Drops Lemon Essential Oil (I use Young Living Oils and 20 drops costs = 80¢)
    OR you could use a Fragrance Oil which is even less expensive (2¢ per drop vs 4¢ per drop)
  • Glass Jar for storage = FREE (remove the sticky label in seconds with this DIY adhesive remover)

Total Cost = $1.61
This recipe will last 16 loads using 2 Tablespoons each load = 10¢ per load

To Use: Just add 2 Tablespoons of your homemade laundry scent booster directly in to your washing machine tub before you add your clothing.

This recipe is safe for HE washers also.

So as you can see, you don’t need to spend extra money to have fresh smelling clothes and towels.

A laundry scent booster is simple to make in just a few minutes with ingredients you probably already have on hand.

You’ll feel like such a smarty with your salt knowledge as well as your laundry freshening skills.
