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.

  • Nellie's Laundry Soda can clean regular household loads effectively without leaving detectable lingering scent on fabrics.

  • The metal tin format can reduce waste compared with liquid laundry products and can help avoid plastic jug storage.

  • The laundry soda can be used in cold washes and still perform adequately for everyday dirt and odors.

  • The product can avoid washing-machine buildup while cleaning regular loads, which helps keep maintenance simple.

  • The laundry soda may struggle with heavy grease or stubborn stains unless stains are pre-treated or boosters like Oxiclean are added.

  • The laundry soda lacks enzyme cleaner and oxygen bleach, which can limit performance on sweat, oil, and food stains.

  • The laundry soda can be less effective for very dirty clothes, and it may require clothes to be only lightly soiled for good results.

  • The ingredient profile includes Linear Alcohol Ethoxylate, which can leave traces of ethylene oxide and 1,4-dioxane during manufacturing.

Yes it is.. "Pros: Highly effective for everyday dirt, leaves no soapy residue, safe for septic systems, and comes in reusable/recyclable metal tins rather than plastic jugs.
  • Cons: Because of its simple formula, it may struggle with heavy stains or grease."

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