More Than Just a Laundry Booster
This single box of washing soda can replace half a dozen specialized cleaners under your sink.
ARM & HAMMER Super Washing Soda is one of those classic, no-frills products that has survived for a reason: it’s incredibly versatile and effective. Whether you’re trying to get tough stains out of laundry, degrease your kitchen, or even polish silverware, this simple powder is a powerful tool for homeowners who appreciate practical, multi-purpose solutions.
- A Serious Laundry Upgrade Adding this to a load with liquid detergent noticeably boosts cleaning power, especially on tough food stains like mustard, just as the box claims. It really does help get whites whiter.
- A Powerful Degreaser When mixed with hot water, it creates a potent solution that cuts through grease on stainless steel sinks, stovetops, and even grimy garage floors.
- Fragrance-Free Odor Killer Instead of masking smells with perfumes, this soda neutralizes them completely. It’s perfect for musty towels or workout clothes, leaving them smelling genuinely clean, not scented.
- Not Just for Laundry The versatility is its strongest asset. I’ve used it to clean tile grout, deodorize drains, and make a paste to remove tarnish from an old brass candlestick.
Boost your liquid laundry detergent’s performance by up to 15% for whiter, brighter clothes. This versatile, fragrance-free powder also tackles tough grime on sinks, stainless steel, and tubs.

Common questions
How is this different from ARM & HAMMER Baking Soda?
Super Washing Soda is sodium carbonate, while Baking Soda is sodium bicarbonate. Washing Soda is much more alkaline (higher pH), making it a more powerful cleaner and degreaser. It is not for consumption, whereas baking soda can be used in cooking.
Can I use Super Washing Soda in my high-efficiency (HE) washing machine?
Yes, you can. Since it’s a laundry additive, you typically add it directly to the drum with your clothes before starting the wash cycle. It’s a low-sudsing powder, making it compatible with HE machines.
How do I use it to clean surfaces like a bathtub or sink?
For general cleaning, you can make a solution by dissolving about a half-cup of Super Washing Soda in a gallon of warm water. Apply with a sponge or cloth, scrub the surface, and then rinse thoroughly with clean water.
Is it safe to use on all metals when polishing?
The product is listed as effective for silver, gold, brass, and copper. However, it is an abrasive cleaner, so you should always test on a small, inconspicuous area first. It is not recommended for use on aluminum, as the high alkalinity can cause it to discolor.
ARM & HAMMER Super Washing Soda is an outstandingly effective and versatile cleaner that lives up to its old-school reputation.
