Things to Consider Before Buying Laundry Scent Booster

Laundry Scent Booster Reviews


Any scented thing can trigger bad reaction if you are allergic to that particular smell or ingredient used in that product.

For this reason, it’s advised to read out the ingredients or have a look at the laundry scent booster reviews to see if anyone has any bad experience with it.

Also, before putting any scent in the washing machine, check to see if any of your family members is sensitive to any particular ingredient.   

For instance, if your kid is allergic to herbs, it’s probably a good idea to avoid all sorts of plant-derived scents as doing so might cause body rash on him/her.


There are different types of laundry scent boosters available in the market. Depending on your preference, you can choose to purchase this product in liquid, detergent or bead forms.

Each type works in different ways to freshen up your clothes. Liquid or detergent fresheners require a bit of guessing to measure properly. Beads or crystals, on the other hand, can easily be counted or poured in a cap for the right measurement.

For people who want a hassle-free experience, there are mini packs available that contain enough beads inside to be sufficient for one load of laundry.

However, in that case, make sure that pack dissolves completely in the water and doesn’t leave any plastic film inside the washer.

Scent Intensity

Mild or bold?

Which one matches your personality the most?

Bold scents usually last for the longest time while giving you freshness all day long! Some of the bold scents involve citrus flavor, strong floral smell etc.

For people who prefer mild scents, there are formulas that contain fragrance just enough to give your cloth a fresh, laundered smell. These scents don’t last for a long time and need to be used more frequently for that reason. You can also use it when folding a shirt that will get rid of bad smell although you keep the shirt folded for a long time.

Machine Compatibility

Generally, standard washing machines are compatible with all sorts of scent boosters.

High-efficiency machines (HE), on the other hand, is a different story. The mechanism of a high-efficiency machine is such that it uses 50% less water than a traditional machine. As they are energy-efficient, they also consume only 20-50% of the energy consumed by a traditional washer.

For these reasons, HE machines require special products that have low-suds and quickly disperse into the water.

The best laundry scent booster should have the ability to work in less water and not create excess suds even in HE washers. Also, the scent booster shouldn’t leave any sticky film that may lead to extra rinse cycles.

Common Questions and Answer

Q1. How Do Laundry Scent Boosters Work?

Ans: Scent boosters come in the form of beads/crystals, liquid or detergent that are packed with fresh scents. When you put these fresheners into the washer, the component dissolves itself into the water and leaves a long-lasting fragrance on your fabric that you wouldn’t get from your standard detergent.

Q2. Can You Put Scent Boosters In The Dryer?

Ans: No, absolutely not!

Fabric fresheners are designed to work with water. Make sure you toss the scent boosters into the drum of your washer before adding your clothes. Then use your standard detergent alongside the boosters for the best result.

Q3. Does Scent Boosters Soften Up The Fabric?

Ans: No, that’s a job for the fabric softener.

Scent boosters only add a refreshing smell to your laundry, nothing less or nothing more. If you want to improve the texture of your cloth, you need to use fabric softener for that purpose.

Q4. Can You Use Scent Booster As Air Freshener?

Ans: It depends on what type of fabric freshener you are using.

Boosters that come in bead forms can usually be used as an air freshener. Simply place a few beads into a spray bottle and fill it up with water.

Leave it overnight and give the bottle a little shake in the morning to mix everything. There you go! Your brand-new air freshener is ready to roll!

Final Words

Just like a clean, fresh-scented cloth can put you in people’s good note, a whiff of bad smell will turn heads as if you’ve come from a swamp!

Not interested in turning people’s mood off?

Invest in the best laundry scent booster and take a fresh clean scent everywhere you go!

From spring flowers to bright fruity flavor, there are various fragrance options available to entice your sense. Just pick the one you like the most and smell the difference right away!
