If you’re trying to simplify your cleaning supplies while keeping things powerful and eco-friendly, ARM & HAMMER Super Washing Soda is one of those quiet classics that deserves a permanent spot in your pantry.
It’s been around for generations, and yet in 2025, it’s having a major comeback—thanks to more people searching for simple, single-ingredient solutions that actually work.
Before diving into its many uses, let’s take a closer look at what makes this humble box of sodium carbonate such a cleaning powerhouse.
Unleashing the Power of Pure Sodium Carbonate
Most cleaning products today come with a long list of ingredients you can barely pronounce. ARM & HAMMER took the opposite approach—keeping it 100% sodium carbonate, also known as washing soda. No phosphates, no dyes, no synthetic fragrances. Just a single, naturally derived compound that packs enough punch to clean, deodorize, and brighten across your entire home.
That purity is exactly what sets it apart. By softening water and breaking down oils and grime, washing soda allows detergents and soaps to perform far more effectively. The 55 oz box gives you plenty to work with, whether you’re deep-cleaning your kitchen or brightening a load of laundry.
Washing soda isn’t new—it’s been trusted for over a century. But in an age of “green cleaning,” its simplicity has made it cool again.
Everyday Cleaning Applications
Before diving into laundry, let’s talk surfaces. Super Washing Soda shines (literally) in multiple areas of the home:
Kitchen Degreaser
Greasy stovetops and dull sinks meet their match here. Mix half a cup of washing soda in a gallon of warm water and watch as it cuts through layers of residue. For stainless steel and enamel sinks, it restores that fresh, just-cleaned shine without harsh chemicals.
Bathroom Savior
Soap scum and hard water stains—two universal cleaning nightmares—are no match for sodium carbonate’s alkalinity. Using the same half-cup-per-gallon ratio, wipe down tiles, shower doors, and tubs to dissolve buildup and brighten your bathroom’s surfaces.
Outdoor & Garage Cleaning
From plastic patio chairs to concrete garage floors, this stuff can do it all. A slightly stronger solution (¾ cup per gallon) works wonders on oil stains and grime buildup.
Laundry’s Secret Weapon
Now let’s talk about where this product really shines—your laundry room.
Washing soda acts as a powerful laundry booster, improving detergent performance by up to 15%. It works by softening water and maintaining the right pH balance for optimal stain removal. Just add about half a cup per load alongside your regular detergent.
If you live in a hard-water area, that small addition can make a huge difference—your clothes come out softer, cleaner, and brighter. For HE washers, use about a quarter cup per load to avoid oversudsing.
One of its best perks? It actually neutralizes odors rather than masking them. Those lingering smells in gym clothes or towels disappear, leaving fabrics naturally fresh.
DIY Cleaning and Stain Treatments
Beyond its standard uses, washing soda opens the door to all sorts of DIY cleaning recipes.
- All-Purpose Cleaner: Dissolve 2 tablespoons in 2 cups of warm water and pour into a spray bottle for daily use.
- Heavy-Duty Degreaser: Combine ¼ cup with 2 cups of hot water to tackle kitchen grease.
- Laundry Pre-Soak: Add ½ cup to a basin of warm water for tough stains or dingy whites.
- Stain Paste: Mix 4 tablespoons with ¼ cup of warm water for a paste that targets stubborn spots like grass or blood.
When experimenting with homemade cleaners, always label your solutions and store them properly—they’ll usually last about a month.
Safe, Simple, and Environmentally Smart
While washing soda is safe when used correctly, it is still alkaline. That means you should wear gloves when handling concentrated mixtures and avoid contact with aluminum or fiberglass surfaces. Store it tightly sealed in a dry place to prevent clumping.
Environmental bonus: it’s phosphate-free, meaning it won’t contribute to water pollution. By choosing a cleaner that’s both effective and eco-conscious, you’re doing your home—and the planet—a favor.
