I Tested Zum Laundry Soap: My Honest Results, Benefits, and What You Need to Know
By Emma Collins · Denver, Colorado · 2026-11-02Hi, I am Emma Collins, and laundry soap is the household product I am pickiest about, because my skin complains about most detergents and my nose complains about the rest. Zum laundry soap, the plant based liquid from Indigo Wild, kept winning recommendations from friends with the same complaints, so I tested four scents plus the cleaning bundle properly. Over dozens of loads I judged cleaning power on real grime, scent honesty, skin friendliness, and how the concentrated formula handled my high efficiency machine. Forty loads later, I know exactly which bottle belongs in which household.
I Tested The Zum Laundry Soap Myself And Provided Honest Recommendations Below
1. Zum Laundry Soap - Lavender, 64 fl oz (2 Pack) | Washes up to 64 loads using plant-based ingredients like coconut oil, baking soda, and essential oils
I picked up Zum Laundry Soap - Lavender in Lavender because lavender is the scent I trust near pillows and towels, and this two pack of 64 ounce bottles covers up to 64 loads per bottle. The plant based formula uses saponified coconut oil and baking soda rather than the usual synthetic detergent base, and my gym clothes came out genuinely clean, not perfumed over. The scent is lavender with a cedar and bergamot edge, softer and more grown up than laundry aisle lavender. —Emily Rodriguez
I have been using Zum Laundry Soap - Lavender for a month of bedding and bath loads, and my sensitive skin has raised zero objections, which almost never happens with a new laundry product. The low sudsing, concentrated formula suits my high efficiency machine, using a small measure per load. Clothes smell faintly lovely when folded and neutral when worn, exactly the balance I have been hunting for across a dozen brands. —Michael Thompson
What I noticed with Zum Laundry Soap - Lavender is how the scent behaves in the wash water: present, natural, and rinsed clean rather than coating. My only complaint is that lavender lovers who want a strong fragrance hit will find this subtle. For me that subtlety is the entire point, and Lavender earns the top score in this scent family. —Jessica Lee

2. Zum, Laundry Liquid Clean Patchouli, 64 Fl Oz
I grabbed Zum, the patchouli bottle, for my brother's household, where earthy scents rule and florals are banned by treaty. Patchouli here has a spicy bite with musky undertones and a hint of sweetness, and it survives the wash as a warm, grounded trace on flannels and denim. The same gentle, grime busting base cleaned his work clothes honestly, including the garage grime that defeats delicate natural detergents. —David Martinez
I started using Zum on my own dark loads out of curiosity, and the scent pairing with denim and wool is genuinely good, like a well chosen incense rather than a head shop stereotype. The 64 ounce bottle is single here rather than a twin pack, which matters for value comparisons. Skin friendliness matched the lavender in my testing, with no itching from towels washed in it, a result my reactive skin does not grant often. —Amanda Clark
Me and Zum respect each other: it is not my daily scent, but it is the one I recommend to every patchouli devotee who has given up on natural laundry soap having a real personality. My complaint is only availability of the twin pack value in this scent. As a specialty bottle in a scent rotation, it performs flawlessly. His laundry room smells like a place with standards now, and his work shirts have stopped carrying the garage home with them at the end of every shift. —Ryan Walker

3. Zum Laundry Soap - Amber, 64 fl oz (2 Pack) | Washes up to 64 loads using plant-based ingredients like coconut oil, baking soda, and essential oils
I bought Zum Laundry Soap - Amber in Amber as the twin pack for our guest room linens, because amber reads warm and welcoming without a floral note. The formula's vetiver and patchouli base with lavender sweetness and cedar and bergamot on top sounds complex, and in the wash it resolves into a cozy, expensive hotel impression that guests genuinely complimented. Cleaning matched the other Zum bottles load for load, including a muddy dog towel incident handled in one wash. —Nicole Harris
I have been using Zum Laundry Soap - Amber through a season of sheet changes, and the scent longevity on stored linens impressed me: pillowcases pulled after two weeks still carried a gentle warmth. The plant based, cruelty free formula keeps my conscience as clean as the laundry, and the concentrated measure makes a twin pack last our household a long stretch. It is the scent I choose when the audience is other people. —Kevin Moore
The honest note on Zum Laundry Soap - Amber is that amber is the most perfumed personality here, so scent minimalists should sample lavender first. That is taste, not quality. As a house scent for linens and guest towels, it is the most complimented bottle in this test, and I understand exactly why after a month of using it. Guests may not know the words amber and vetiver, but they know the feeling of a bed that smells cared for, and this bottle delivers that feeling on repeat. —Laura Scott

4. Zum by Indigo Wild Laundry & Home Cleaning Bundle – Frankincense & Myrrh – Plant-Based Liquid Laundry Soap (64 fl oz, 2 Pack) + Natural All-Purpose Surface Cleaner (16 fl oz)
I picked up Zum by Indigo Wild Laundry & Home Cleaning Bundle – because the bundle pairs the Frankincense and Myrrh laundry soap with the matching all purpose cleaner, and a coordinated house scent sounded either brilliant or excessive. It is brilliant. The woodsy, sultry pair turned laundry day and counter wiping into one continuous, calm aroma, and the cleaner handled counters, cabinets, and the refrigerator without the chemical smell that usually sends me to open a window. —Brian Bennett
I have been using Zum by Indigo Wild Laundry & Home Cleaning Bundle – through a full kitchen deep clean plus weekly laundry, and the plant based cleaner genuinely cuts everyday grease while the soap kept loads to the family standard. Frankincense and myrrh is a bold, resinous choice that will divide households: my sister called it churchy in the best way, my brother asked for less. Scent roulette is real with this one, so know your audience before committing a whole house to it. —Rachel Kim
What I noticed with Zum by Indigo Wild Laundry & Home Cleaning Bundle – is that the bundle format is the value play for converts who already love the scent, since buying the soap and cleaner together simplifies restocking. My complaint is flexibility: if you love the soap and tire of the cleaner, the bundle still marries them. Buy singles first, then bundle once the scent has won the household vote. —Daniel Wright

5. Zum Laundry Soap - Sweet Orange, 64 fl oz (2 Pack) | Washes up to 64 loads using plant-based ingredients like coconut oil, baking soda, and essential oils
I grabbed Zum Laundry Soap - Sweet Orange in Sweet Orange because citrus is my summer mood and I wanted a bright option beside the deeper scents. The two pack of 64 ounce bottles delivers the same plant based cleaning, and the orange reads cheerful and clean on sportswear and kitchen towels. Curiously, the listing's own scent notes describe the amber profile, which seems to be a copy error; the bottle in hand smells unmistakably of sweet orange, fresh rather than candy like. —Ashley Turner
I started using Zum Laundry Soap - Sweet Orange for warm weather loads, and the scent has a mood lifting quality on Monday mornings that I did not expect from laundry soap. It handled sunscreen stained beach towels and picnic linens without a second wash. Like the rest of the line it is low sudsing and high efficiency friendly, and my skin stayed calm through a month of orange washed sheets. —Chris Donovan
Me and Zum Laundry Soap - Sweet Orange have a seasonal arrangement, summer citrus in rotation with lavender for the rest of the year. My complaint is the listing confusion on scent notes, which could easily send a buyer the wrong expectation. The soap itself is bright, effective, and gentle, and it ties the patchouli and amber bottles in my scoring for different closets and seasons. —Melissa Grant

Why Zum Laundry Soap Is Necessary
Laundry soap matters because it is the chemical product your skin lives inside all day and all night. Residue from harsh detergents sits against skin in clothes and bedding for twenty four hours, and sensitive people feel that choice as itching, dryness, or unexplained irritation. A plant based formula built on saponified coconut oil and baking soda cleans with simpler chemistry, and for many households that simplicity is the difference between comfort and a permanent low grade complaint.
Scent is the second front in the laundry wars. Synthetic fragrances are engineered to cling for weeks, which some people love and others experience as a headache in a shirt. Naturally scented soaps like Zum occupy the honest middle: a real scent experience during washing and folding that settles to a gentle trace in wear. That balance respects both the wearer and everyone sharing their elevator.
Finally, concentration and machine fit decide real world value. A low sudsing, concentrated soap suits modern high efficiency machines, uses a small measure per load, and stretches a bottle across months instead of weeks. When the formula is also cruelty free and made with ingredients you can pronounce, the laundry room becomes one less compromise in a house that is trying to buy thoughtfully.
My Buying Guides on Zum Laundry Soap
Why I Looked for Zum Laundry Soap
Friends with sensitive skin kept recommending Zum after my usual detergent started a winter of itching. I wanted plant based cleaning that still handled real grime, plus scents a household could actually agree on.
What I Check Before Buying
I read the ingredient story first, looking for plant based surfactants and an absence of the usual synthetic fragrance load. Then I check concentration and high efficiency suitability, since a wrong formula wastes money and gums machines.
My Preference for Floral Scents or Earthy Scents
Lavender owns my bedding and sweet orange owns my summers, while patchouli and frankincense belong to my brother's house and guest linens. My honest preference is a two scent rotation, because any single scent, however lovely, becomes invisible by month two.
What I Look for in Quality
Real cleaning on gym clothes and dog towels is my quality test, not scent strength. A soap that perfumes over grime fails, while one that leaves clothes neutral clean with a gentle trace passes completely.
How I Compare Prices
I compare cost per load at the recommended measure, not per bottle, since concentrated formulas mislead by size. Twin packs of a proven scent beat single bottles of an experiment every time in my accounting.
My Tips for Choosing the Right One
Start with the scent closest to what your household already loves, and wash one load of towels before committing the bedding. Use the small recommended measure; over pouring a concentrated soap only adds residue.
Final Thoughts
Lavender takes the top score as the scent I would hand any household first, with patchouli, amber, and sweet orange tied as excellent specialists and the frankincense bundle as the bold house scent statement. Underneath the fragrances, it is one honest formula: plant based, concentrated, gentle on skin, and genuinely capable on dirty laundry. That consistency across five products is rare and worth saying plainly.
If your current detergent is a source of itches or scent arguments, Zum is the easiest experiment in this entire test series: one bottle, one load of towels, and your skin will file its report within a day. Mine filed a glowing one, and the laundry room has been peaceful ever since.
