Chlorine Bleach vs. Oxygen Bleach: When to Use Each

Use chlorine bleach (sodium hypochlorite) on white, colorfast fabrics when you need strong whitening or sanitizing, and oxygen bleach on colors, everyday stains and anything labeled "do not use chlorine bleach" (OxiClean; Whirlpool). Never mix chlorine bleach with ammonia or acids such as vinegar, because both make toxic gas (Washington State Department of Health).

Key takeaways

• Oxygen bleach is the color-safe choice. Chlorine bleach is stronger and belongs on white, colorfast fabrics only.
• For chlorine bleach, use 1/3 cup in a standard washer and 1/4 cup in a high-efficiency (HE) washer, and never pour it straight on fabric.
• For oxygen bleach powder, soak stained items 1 to 6 hours in warm to hot water before washing.
• Never combine chlorine bleach with ammonia, vinegar or other acids, and do not use chlorine bleach and oxygen bleach together.
• Test colorfastness on a hidden seam first, even with color-safe products.

What is the difference between chlorine bleach and oxygen bleach?

Chlorine bleach is liquid sodium hypochlorite diluted in water, while oxygen bleach releases oxygen and hydrogen peroxide when it dissolves (OxiClean; Whirlpool). Both lift color from stains, but they differ in strength, fabric safety and germ-killing.

The comparison above follows Maytag, Whirlpool and OxiClean: chlorine bleach is the more potent whitener, while oxygen bleach is gentler and better for repeated use (Maytag; Whirlpool).

What is oxygen bleach made of?

Oxygen bleach, also called color-safe or non-chlorine bleach, comes in three types: hydrogen peroxide, sodium percarbonate and sodium perborate (OxiClean). Sodium percarbonate is a solid compound of washing soda (sodium carbonate) and hydrogen peroxide (Whirlpool; Maytag).

What is the strongest oxygen bleach?

Sodium percarbonate. It is typically more concentrated than perborate, which is generally less potent (Maytag).

Powders, liquids and pods all work on the same principle: the product releases oxygen that breaks down stain molecules (Maytag).

Is oxygen bleach and OxiClean the same thing?

OxiClean is a brand, and some of its products contain oxygen bleach (OxiClean). Its Versatile Stain Remover is a powder that activates when added to water (OxiClean). Read the ingredient list on any product to see whether it relies on percarbonate or something else.

Is Clorox an oxygen bleach?

Regular Clorox liquid bleach is sodium hypochlorite, a chlorine bleach (Clorox). Some makers also sell color-safe lines: UGA Extension lists Clorox II as an example of a sodium perborate bleach (UGA Extension). The label's active ingredient tells you which kind you hold.

Is oxygen bleach color-safe, and can you use OxiClean on colors?

Oxygen bleach is gentler than chlorine bleach and is safe on most colored fabrics, but only colorfast ones (Whirlpool). OxiClean says its Versatile Stain Remover is safe on colorfast fabrics and warns that not all clothing is colorfast (OxiClean). That also covers black clothes: test a hidden seam first, because loose dye can still fade.

UGA Extension gives a quick test for sodium perborate bleach: mix 1 teaspoon in 1 cup of hot water, put a few drops on a hidden spot for 10 minutes, and look for color bleed (UGA Extension). For chlorine bleach, mix 1 tablespoon in 1/4 cup of water, apply one drop for 1 minute, blot dry and check for color change (UGA Extension).

Check the care label first: it takes the guesswork out of bleach symbols, and our care label symbols guide explains each one.

How do you use chlorine bleach in laundry?

Add measured, diluted bleach to a load of white or colorfast, bleach-safe fabrics; never pour it undiluted onto clothes (Clorox; UGA Extension). Clorox lists these amounts for its bleach (Clorox):

1. Sort. Pick bleach-safe whites and colorfast items, and skip wool, silk, mohair, leather, spandex and non-fast colors (Clorox).
2. Choose the cycle. A heavy-duty cycle with hot water and an extra rinse performs best (Clorox).
3. Add it. Use the bleach dispenser, or dilute the measured bleach in 1 quart of water and add it 5 minutes after the wash starts (Clorox).
4. Add detergent too. Clorox says to add both detergent and bleach when the washer is about half full (Clorox).

UGA Extension also says chlorine bleach can weaken and yellow fabrics with some resin finishes, may permanently yellow some nylon, and should not go on fire-retardant finishes (UGA Extension). Chlorine bleach used too often can damage even tough fabrics (Whirlpool).

For whites that need a full routine, see our guide to washing white clothes.

How do you use oxygen bleach, and how long should it soak?

For stains, fill the scoop to line 2 to 4 per gallon of water, soak items 1 to 6 hours, then wash as normal (OxiClean). Tough stains can need longer, and Maytag says dingy whites may need a longer soak than you would use with chlorine bleach (Maytag).

• In the machine: add the powder with detergent to the drum before the laundry, not into the bleach dispenser (OxiClean).
• Water temperature: it works in any temperature but best in warm to hot, never boiling. For a cold wash, dissolve it in hot water first (OxiClean).
• General rule: use the warmest water that is safe for the fabric, and follow the package for dosage (Whirlpool).

Do not combine the soak with chlorine bleach, because chlorine bleach stops the stain removal action of sodium perborate bleach (UGA Extension). For a stain-specific method, start with our stain-by-stain guide.

Does oxygen bleach disinfect?

Not reliably. Maytag says oxygen bleach may be less effective than chlorine bleach at disinfection (Maytag), and OxiClean lists disinfecting as a benefit of chlorine bleach only when the product is registered with the EPA as an antimicrobial pesticide (OxiClean).

To sanitize laundry, Clorox says to use unscented, EPA-registered bleach with a germ-kill claim on the label, and to make sure the laundry contacts the solution for 10 minutes (Clorox). Scented bleach is not approved for sanitizing (Clorox).

Can you mix bleach with detergent, vinegar, ammonia or oxygen bleach?

Detergent is fine: the washer mixes it with bleach in the wash water (Clorox). Everything else on this list is a safety problem.

• Ammonia: bleach and ammonia produce toxic chloramine gases that cause coughing, nausea, shortness of breath and chest pain (Washington State Department of Health). Ammonia is also in some glass cleaners and in urine (Washington State Department of Health).
• Vinegar and other acids: bleach mixed with an acid gives off chlorine gas, even low levels irritate the eyes, throat and nose, and very high levels can be fatal (Washington State Department of Health). Vinegar, some toilet bowl cleaners and rust removers are acids (Washington State Department of Health). Our vinegar in laundry guide covers when to add it instead.
• Hydrogen peroxide: bleach also reacts with hydrogen peroxide, the base of oxygen bleach (Washington State Department of Health).
• Oxygen bleach powder: chlorine bleach cancels the stain action of perborate bleach, so separate loads are the safe plan (UGA Extension).

If someone has symptoms after mixing chemicals, contact a health care provider or call 911 (Washington State Department of Health). Also keep chlorine bleach out of metal containers; it can darken aluminum (UGA Extension).

Which bleach should you use for which job?

For mildew, MU Extension says to soak in the perborate solution for 30 minutes or longer, and to use the chlorine solution for 5 to 15 minutes, followed by a weak vinegar soak to stop the bleach (MU Extension). Never use chlorine bleach on silk, wool or spandex (MU Extension).

What can you use instead of oxygen bleach?

UGA Extension lists 3 percent hydrogen peroxide as a safe bleach for all textile fibers; test colorfastness and keep it out of metal containers (UGA Extension). Our hydrogen peroxide stain remover guide shows how to use it on specific stains. Sodium perborate bleach is another option (UGA Extension). We do not give a mix-your-own recipe, because the sources we read did not test one.

Using bleach at a laundromat

Washer makers say to check the owner's manual before adding any bleach (Whirlpool). Public machines have no manual to read, so check the posted rules and ask the attendant at your self-service laundromat. If you would rather not handle bleach at all, a wash-and-fold service can sort and wash a load for you.

Frequently asked questions

Does OxiClean bleach clothes?

OxiClean's Versatile Stain Remover uses oxygen to remove stains and is safe on most colorfast fabrics. It lifts stains and brightens rather than stripping color the way chlorine bleach can. Test a hidden seam first because not all clothing is colorfast.

Is borax the same as oxygen bleach?

No. UGA Extension describes borax as a mildly alkaline powder used as a water softener and mild cleanser, and lists sodium perborate bleach as a separate product. Borax is covered in our borax for laundry guide.

How can I make my own oxygen bleach?

Sodium percarbonate is a compound of washing soda and hydrogen peroxide, but we found no tested home recipe in the sources we read. Buying a percarbonate product and following its label is the safer route.

Is oxygen bleach safe for septic tanks?

OxiClean states that oxygen bleach is safe for septic tanks when used as directed. Follow the product label for amounts.

How much bleach goes in a washer?

Clorox lists 1/3 cup for normal whitening in a standard washer and 1/4 cup in an HE washer. Use the dispenser and never pour bleach straight on fabric.
