This is a fantastic and inexpensive way to make sure your clothes get really clean! There is no added fragrance or dyes, so it works well for even sensitive skin. I have really hard water and this really gets my clothes clean even though the water is really hard. It also has zero impact on color fading so you don’t need to worry about bright colors fading when using this product. It works with any type of laundry detergent and I have used this with laundry pods, laundry sheets, laundry liquid, and laundry powder…. It works well with all forms of laundry soap! It really helps with removing stubborn laundry stains, as well as making clothes look clean and not at all dingy. This product works well on more than just laundry! ... show more

    • “Clean Clothes Without the Fillers
Color: Multi Size: 55 Ounce (Pack of 1)
I bought this washing soda because so many commercial laundry detergents are packed with fillers, dyes, and artificial fragrances that can trigger reactions in sensitive skin. As a mom with allergy‑prone kids, I wanted full control over what touches their clothes every day. The box of ARM & HAMMER Super Washing Soda arrived in perfect condition, and I ordered a second one to keep on hand for future batches or other household cleaning needs. When mixed with a few simple ingredients in a 5‑gallon bucket, the washing soda dissolved smoothly and created a clean, fragrance‑free detergent base. After several loads, I’ve had zero skin irritation in the family, and the clothes come out just as clean—if not cleaner—than with the big retail brands. No residue, no heavy scent, and no mystery additives. Beyond laundry, this washing soda has become a staple in my home because it’s versatile and safe enough for a family environment. I’ve already used it to boost heavily soiled laundry, pre‑treat grease stains, clean tile and grout, deodorize garbage cans, and remove soap scum in the bathroom. Having a product that handles all of that without unnecessary chemicals gives me real peace of mind. This is an excellent choice for anyone who wants to avoid the long list of additives found in commercial detergents, especially families dealing with allergies or sensitive skin. It’s also a smart way to reduce cost‑per‑load while keeping your home clean with simple, effective ingredients. It may not be ideal for those who prefer strong fragrances or pre‑mixed detergents, but for ingredient‑conscious households, it’s a standout. ... show more

    • Highly recommended for a powerful yet natural cleaning solution
Color: Multi Size: 55 Ounce (Pack of 1)
Review Image by Lawrence J. Gist II

Review Image by Lawrence J. Gist II
ARM & HAMMER Super Washing Soda is a multipurpose household cleaner that serves as both a laundry booster and a general home cleaning agent. Made from 100% sodium carbonate, it is a natural, fragrance-free solution that enhances detergent performance, tackles stubborn stains, and works as an effective cleaner for various surfaces. This review will analyze its pros and cons in detail and provide recommendations based on performance, versatility, and value. Pros 1. Highly Effective Laundry Booster • Enhances Detergent Power: Super Washing Soda helps break down tough stains, grease, and odors, making it an excellent addition to regular laundry detergent. • Softens Water: It reduces water hardness, allowing detergents to work more effectively, especially in areas with hard water. • Brightens Whites and Colors: It lifts dullness from fabrics without the use of bleach, making clothes look fresher. 2. Versatile Cleaning Agent • Multi-Surface Cleaner: It can be used for cleaning kitchen countertops, bathroom tiles, stovetops, and even outdoor surfaces. • Grease and Grime Removal: Cuts through grease buildup on cookware and kitchen appliances when mixed with warm water. • Carpet and Upholstery Stain Removal: Works well as a pre-treatment for tough stains on carpets and furniture. 3. Eco-Friendly and Non-Toxic • No Harsh Chemicals: Unlike many commercial cleaners, it contains no phosphates, fragrances, or artificial additives. • Biodegradable and Safe for the Environment: Since it is made from a naturally occurring mineral, it is safe for septic systems and eco-conscious households. 4. Cost-Effective • Affordable Alternative to Commercial Cleaners: A single box can replace multiple cleaning products, saving money in the long run. • Long Shelf Life: Unlike liquid cleaners, it does not degrade over time when stored properly. Cons 1. Can Be Harsh on Skin • Alkaline Nature: As a strong alkaline substance (pH ~11), it can cause skin irritation. It is recommended to use gloves when handling it directly. 2. Not Ideal for Certain Surfaces • Can Damage Delicate Materials: It should not be used on aluminum, glass, or varnished surfaces, as it may cause etching or dulling. • May Leave Residue on Some Fabrics: If not dissolved properly, it can leave a white powdery residue on clothes. 3. Requires Proper Storage • Absorbs Moisture Easily: If not stored in a sealed container, it can clump over time, making it difficult to use. 4. Lacks Scent and Fabric Softening Properties • No Added Fragrance: While great for those sensitive to scents, some users may miss the fresh smell provided by scented detergents or boosters. • Not a Fabric Softener Substitute: Unlike baking soda or vinegar, it does not naturally soften fabrics. Recommendations For Laundry Use: • Dissolve in warm water before adding it to the wash cycle to prevent residue. • Pair with white vinegar as a fabric softener alternative. • Use with detergent in heavily soiled loads for best results. For General Cleaning: • Mix with warm water for a powerful grease-cutting solution. • Avoid using on aluminum or polished surfaces. • Store in an airtight container to prevent moisture absorption. For Safety & Storage: • Always wear gloves when handling directly. • Keep out of reach of children and pets. • Store in a dry place to prevent clumping. Final Verdict ARM & HAMMER Super Washing Soda is an excellent addition to any household looking for a powerful, natural, and budget-friendly cleaner. Its versatility in laundry and home cleaning makes it a valuable staple. However, due to its alkaline nature, users should handle it with care and avoid using it on delicate surfaces. If you need a fragrance-free, eco-conscious cleaning solution, this product is a fantastic choice. ... show more
