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.

800 loads? A slow weekend for me.

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.

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.

In case you were wondering like I was, this is not a detergent additive. It replaces your regular detergent like Persil/Tide etc.

We've been using it for a few years. I have no complaints about effectiveness for normal use with just a tablespoon scoop per load. I pretreat stains, but no different than I did with other detergents. It does not leave behind a scent that I can detect. I don't do stain removal tests, but I can say that it seems to do a very good job removing dog smells from their various towels and blankets.

We tried it out initially because I prefer a powder detergent to avoid most of the front loader smell issues and this has worked.

This 800-load bucket was the same price through Costco in mid-December 2025 as well.

Unless you live for what Hawaii has to offer.

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.

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.

Roughly 7 years if you do 2 loads per weekend.
5 years if you do a 3rd load for bedding etc.

Switched over to this and like the lack of scent and it seems to clean well. Use spot cleaners if something is really bad.
