No enzyme cleaner ingredients, means it won't work well on sweat, oil, food, stains, etc, and won't work well in cold water. And it doesn't have an oxygen bleach.

Community Reviews

Nellie's Laundry Soda is a fragrance-free powder detergent that works well for regular laundry, especially sweat, odors, and everyday dirt, and it leaves no soapy residue or machine buildup. The 800-load tub can last years, with reports ranging from about two to three years for a normal household to much longer at lighter use. It is also septic-safe and less wasteful than liquid detergent. The main drawback is that it can struggle with heavy grease, stains, and cold washes, so pre-treating or adding OxiClean helps. It is a strong fit for routine washing when scent-free cleaning matters most.

Common Questions (5)

  • The 800-load tub can last about 2 to 3 years for a normal household, around 33 months for a family of five, or roughly 5 to 7 years at 2 to 3 loads per week. Actual life depends on how much you dose per load and whether you use larger settings for dirtier laundry.

  • It works well for everyday dirt, sweat, and odors, but it may struggle with heavy grease or stubborn stains because it has no enzymes. Pre-treating stains or adding OxiClean is the practical workaround.

  • It leaves no soapy residue and does not leave a detectable scent on clothes. That makes it a fit for people who want fragrance-free laundry and want to avoid front-loader odor issues.

  • It can work in cold washes, but the formula has no enzymes and may be weaker on sweat, oil, food, and other stains in cold water. For regular laundry, it still cleans well; for tougher loads, pre-treating or adding OxiClean helps.

  • It replaces your regular detergent rather than acting as an additive. Use it in place of Tide, Persil, or similar laundry detergent.

Hawaii. Great place to vacation but horrible place to live.
Agree, Hawaii is hella expensive. It's a playground for billionaires like Oprah, Zuckerberg and Larry Ellison. I went a few times and it wasn't worth it, would rather spend my money in Thailand where I can get 10x the vacation fun for the same costs.

7 big 115 load jugs of Purex are $42 at Walmart by me (they have $3 Walmart cash back instant rebates on each jug) and that gets you 805 loads.

Good deal on volume but Purex is trash. You'd get better results washing with dishwasher detergent like Dawn LMAO

The highest rated detergents usually have the most enzymes, like Tide and Persil. Cheaper brands usually have fewer enzymes. This has none, and isn't even that cheap per load. Costco's own Kirkland Signature Ultra Clean is around 14¢/load, has enzymes, and Consumer Reports rated it top 5.
You could add OxiClean to help some, but even then you're still lacking the enzyme cleaner making this ineffective at cleaning sweat, oil, food stains, etc.
This is a great deal if you're just washing clothes to get sweat and smells out, not intended as a heavy stain removing detergent which many dedicated detergents already specialize in.

The OxiClean powder tubs from 2019 and earlier used to be absolutely amazing at lifting stains. Unfortunately, the recent tubs I've bought feel severely diluted and barely remove anything. It really feels like they are cutting corners on quality now.

It's pretty good for regular day-to-day. But if you have any grease stains you may want to soak the piece of clothing in a vinegar solution before washing it.

Went through the 400 loads tub in probably 3ish years and it never clumped up.

Eh, too much work, but I agree... there is really not that much to detergent. Plus, most detergent scoop cups recommend way more product than you actually need... b/c the more you use, the more often you'll buy a replacement bottle.

Personally, my go-to is the powdered detergent at Costco/Sam's that's usually like a 20-30 lb bucket for $20 or so. For clothes I wear, I detest scents. The Mountain Breeze and other stuff just smells so fake to me. These powdered detergents work fine to take out all of the sweat smells from clothes, as well as most of the dirt. I don't really soil clothes too much in terms of dirt.

However, for linens and towels, I actually do like the scents... so I have Odoban or scented detergent I use depending on how I'm feeling (different smells... I mix it up).

In the event stuff is really dirty.. mainly whites... I have Oxiclean that I'll soak them in overnight.

In terms of pods... thoroughly detest those things b/c I feel like they're money grabs for convenience. I do still buy pods though b/c when I travel, I have a small rubbermaid container I can put about 11 pods in to do wash in sinks and bathtubs on the road.

Works great. But we do pre-treat stains.

But is the 800 loads only using a tiny amount... Would realistically need 2 scoops to get stuff clean or large loads? (most people don't realize when the jugs advertise how many loads, it's the first line for small loads). When I used cheaper stuff like purex I always had to use large load size to get things clean.
If so, you have 400 loads, I do roughly 3-4 per week, so would last a little over 2 years. So cost is around 62 cents per week using 2 scoops at my average frequency.
If it works well that's not a bad deal. Can't comment on that part.
well that's why I started with roughly. 2 years is still a decent enough time for me to not have to remember to pick up something or add it to a grocery list.

Not anymore, I hear the new kirkland detergent is different than the previous version that came in the plastic white and blue bucket. I hear it doesn't wash clothes nearly as well. I'm actively looking for something different. But for now I have one last bucket of the old stuff and now use tide free and clear from Costco.

The nice thing about Costco old plastic bucket version was 200 loads at 3/4 full scoop. And you could get away from using a little more than half a scoop and it would still clean everything well. And small loads only needed a 1/4 scoop. So you could say it was a 300-400 load bucket

Can I store this in the garage? It's such a big container, seems like it would last forever.

Might try using baking soda and turning it into washing soda by baking it to save a little more money. This is a project down the road for me.
