Which bleach should I use for laundry, chlorine or oxygen?

Use chlorine bleach for whites and colorfast fabrics that can take it, at the dose on the bottle, and never on wool, silk, mohair, leather, spandex or colors that run. Oxygen bleach (sodium percarbonate powders sold as stain removers) is the one extension stain charts call "nonchlorine, all-fabric," but its own box is the only source for its fabric limits and water temperature, since no extension source read for this page sets either. Clorox's laundry directions call for 1/3 cup of its bleach for a normal load in a standard washer and filling to the dispenser's max line in an HE machine. Never mix either bleach with ammonia, vinegar or other cleaners. The sourced doses and limits follow.

The two bleaches side by side

The chemistry of each, and their full hazard classes, are on household bleach and oxygen bleach.

Chlorine bleach doses from the maker

From Clorox's laundry directions (May 10, 2024) [4], for whitening and stain removal:

How Clorox says to add it:

• HE washers: "Add bleach and detergent to appropriate dispenser compartments" [4]. If your manual does not say how much the bleach compartment holds, Clorox says to fill only to the max line [4].
• Standard washers: dilute the measured bleach in 1 quart of water and add it about 5 minutes after the cycle starts, once the tub is about half full of water [4].
• Hand washing: 1/4 cup of bleach in 1 gallon of cool water, with the garments soaked for 5 minutes [4].
• Never pour undiluted bleach straight onto fabric [4].

These figures are for Clorox's own regular bleach. Concentrated, splashless and scented products are thicker or stronger and their labels may give different directions; Clorox notes that its Splash-Less label "usage directions may differ" [4]. Read the bottle you own. Its strength also falls as it ages, which does bleach expire? explains.

Clorox's page also gives germ-related laundry directions that apply only to its EPA-registered disinfecting bleach under that product's label. This page does not cover them. CDC adds that "some types of laundry bleach or splashless bleach" are "not appropriate for disinfection" [6], so a bottle sold for laundry is not a substitute for the bleach that the bleach disinfecting solution page calls for.

Testing a fabric before you bleach it

Clorox tells readers to "test for colorfastness to ensure the fabric doesn't become discolored" but gives no method on the page read [4]. Mississippi State University Extension's stain chart gives the general rule for any stain remover: "Always test stain removers on an inside seam or other hidden part of garment for color fastness" [3]. Its bleach advice adds: "do not try to bleach just one area of garment; bleach the entire garment to prevent uneven color removal" [3].

So, for either bleach:

1. Read the care label first. Texas A&M's chart says to read it before anything else and to take "dry-clean only" items to a professional [5].
2. Mix the bleach at the strength you will use in the wash.
3. Dab it on a hidden seam, wait, then blot and check for color change.
4. If the color moves, do not use that bleach on that garment.

Oxygen bleach and water temperature

The question readers ask most about oxygen bleach is how hot the water must be. None of the extension or manufacturer sources read for this page gives a temperature for it. Mississippi State's chart tells readers to launder "in hottest water safe for that fabric" for several stains, and for mildew stains it names an all-fabric bleach in hot water [3], but that advice concerns the fabric and gives no activation temperature for the product. Use the temperature on your box and the care label, whichever is lower.

Church & Dwight's SDS for OxiClean Versatile gives the handling side [2]:

• Incompatible materials: "Combustible materials. Reducing agents. Strong acids, strong bases, strong oxidizers."
• Storage: "Keep container closed when not in use. Store in a dry, cool place."
• Empty packaging: "Container may remain hazardous when empty."

The SDS does not cover soaking. Make up a soaking solution only as the directions on your box describe, and follow the box's own warnings on mixing and storing it.

Never mix, in the wash or in the sink

Mississippi State's chart: "Do not mix stain removal products together. Some mixtures, such as ammonia and chlorine bleach, can produce noxious fumes" [3]. Whirlpool warns against vinegar or "any acid" with bleach, which "creates chlorine gas" [7]. In the laundry room that means:

• no vinegar in the softener compartment of a load that has chlorine bleach in the bleach compartment;
• no ammonia-based stain treatment on a garment that will go into a chlorine bleach wash;
• no chlorine bleach with oxygen bleach in the same load: the OxiClean SDS lists strong oxidizers and strong bases among incompatible materials [2], and chlorine bleach is both.

The pairs and what they release are on cleaners you should never mix.

Where bleach fits in getting a stain out

Bleach is usually the last step, after the stain has been pretreated and washed. For the order to use detergent, enzymes and bleach on a particular stain, go to removing stains.
