Mrs. Stewart's Concentrated Liquid Bluing
Best laundry whitener for those seeking a gentle, fabric-safe brightening solution.
Mrs. Stewart's Concentrated Liquid Bluing is a traditional laundry additive that acts as an optical whitener, making white clothes appear brighter and whiter. Since 1883, this nontoxic and biodegradable formula has been a gentle alternative to bleach, safe for most fabrics and even colors. It works by adding a subtle blue tint to counteract yellowing, creating a brighter white appearance. While it won't remove stains, it enhances the brightness of your laundry without damaging fabric fibers.

Know before you buy
No, this product is not a stain remover or a traditional bleach. It is an optical whitener designed to counteract yellowing and restore brightness to white fabrics.

Unlike chlorine bleach, which chemically strips color and can weaken fabric fibers over time, Mrs. Stewart's is a nontoxic, biodegradable formula that is much gentler on your clothes.
It will not stain if used correctly. You must dilute the bluing in a small amount of water before adding it to your wash or rinse cycle to ensure it disperses evenly throughout the fabric.
