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.

I can't wrap my head around 800 loads of laundry. That might last me the rest of my life.
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.

What can be added along with it to make it more efficient?

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.

Does anyone know an "exact" recipe to make this at home (same ingredients only)? I no longer want this huge bucket around anymore. I used to buy an "identical" generic version but I can't find it anymore. I am going to "cut" the remaining generic I have with "laundry soda" which is the main ingredient of this. I am on a budget. FYI "one tablespoon" is per regular load, not large load.

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 14ยข/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.
