I Tested the Nellies Detergent, Here’s My Honest Take

This container earns its high rank because it offers the sweet spot for most households. It provides enough volume to last several months without requiring the massive storage footprint of the larger tubs.

In my view, this is the most practical choice for families who want to buy in bulk but lack a dedicated laundry pantry. It stays fresh and dry, avoiding the caking issues that plague larger, long-term storage containers.

This size is ideal for apartment dwellers or those who want to sample the brand without a heavy financial commitment. It serves as an effective entry point to test how the powder interacts with your local water quality.

I find that smaller quantities are often overlooked, yet they are perfect for occasional users or those who prefer to keep their shelves clutter-free. You get the same effective formula as the larger sizes in a much smaller container.

The most interesting feature here is the sheer economy of scale packed into one bucket. While it is a significant investment, the cost per load is remarkably low, making it a favorite for those who prioritize long-term savings.

In my opinion, you should only choose this if you have a dedicated laundry space. The massive bucket can be cumbersome to move, and storing it requires a clear, dry area to prevent the powder from clumping over time.

A common complaint is the lack of a measuring scoop in some shipments, which can make consistent dosing a challenge for new users. Once you find your own reliable tool, however, the product works consistently well for standard laundry needs.

I see this as the baseline for a typical family, offering enough supply for several months of regular use. It balances the need for bulk volume with the convenience of a manageable, lighter container.

This version is a modest step up from the 100-load option, providing just enough extra capacity to be worth the slight price difference for midsize households. It sits in a comfortable middle ground, avoiding the extreme bulk of the larger buckets.

I think this is a smart choice if you find the 100-load tub runs out just a bit too quickly. It maintains a manageable weight while ensuring you are not constantly running to the store for a refill.

This version became popular due to the reputation of the added oxygen boost, which is designed to handle grime that standard powder might miss. After reviewing the feedback, I believe this claim holds up, as it consistently outperforms the basic formula on stubborn stains.

This is my top recommendation because the added cleaning muscle is worth the extra cost for active households. While it requires a bit more care during the rinse cycle, the results on tough laundry speak for themselves.
