Choosing the right Laundry Additives
-
Purpose (Stain vs. Brightening vs. Odor)HighDifferent laundry boosters target different problems. Enzymatic cleaners tackle protein stains, optical brighteners make whites appear brighter, and products like washing soda soften water and lift grime.Look forA product that specifically addresses your primary laundry issue, whether it's stains, dinginess from hard water, or odors.AvoidA generic 'all-purpose' booster that doesn't excel at the specific task you need.
-
Formulation (Powder vs. Liquid vs. Pod)MediumBoosters come in various forms. Powders like washing soda are economical and stable, liquids are easy to measure and dissolve, and pods offer mess-free convenience.Look forA form that integrates well with your laundry routine and dissolves properly in your typical wash temperature.AvoidPowders that may clump in cold water if you exclusively use cold wash cycles.
-
Scent ProfileHighSome boosters add strong, lingering scents designed to last for weeks, while others are completely unscented and focus solely on cleaning and odor neutralization.Look forFragrance-free options if you have sensitive skin, allergies, or simply prefer the scent of clean laundry without added perfume.AvoidHeavily perfumed products that may just mask odors instead of truly eliminating them at the source.
-
Water Hardness CompatibilityHighThe mineral content of your water (its hardness) significantly impacts detergent performance. Some boosters, like washing soda, are specifically designed to soften water, making your detergent more effective.Look forA water-softening booster if you live in a hard-water area to prevent dingy laundry and soap scum buildup.AvoidIgnoring your water type, as it's often the root cause of poor laundry results.
Common questions
Can I use ARM & HAMMER Super Washing Soda in a high-efficiency (HE) washing machine?
Yes, you can. Since it’s a low-sudsing additive, it’s safe for HE machines. Just add the recommended amount, typically about a 1/2 cup for a full load, directly into the drum with your clothes before starting the wash cycle, not in the dispenser tray.
How is this different from ARM & HAMMER Baking Soda?
While from the same brand, they are different chemicals. Baking soda is sodium bicarbonate, which is milder. Super Washing Soda is sodium carbonate, a more alkaline and powerful cleaning agent. Washing soda is much better for heavy-duty cleaning and laundry boosting, but it is not edible and is more caustic than baking soda.
Does it really help remove tarnish from silver?
Yes, it works very well for polishing silver and other metals. A common method is to line a pan with aluminum foil, add the tarnished items, sprinkle with washing soda, and pour hot water over everything. The resulting chemical reaction lifts tarnish without abrasive scrubbing.
Is Super Washing Soda safe for septic systems?
Yes, ARM & HAMMER Super Washing Soda is phosphate-free and biodegradable, making it safe for standard septic systems. When used in moderation as part of your normal cleaning routine, it won’t harm the system’s bacterial balance.
ARM & HAMMER Super Washing Soda is a powerhouse product whose effectiveness and versatility far outweigh its simple, no-frills nature. While the dusty powder requires some care in handling, its ability to brighten laundry, eliminate odors, and cut through grease is unmatched at this price point. It’s an essential, high-value addition to any serious cleaning toolkit.
