How Much Bleach to Add to Laundry Without Damaging the Fabric

You want to use bleach in your laundry but you’re not sure how much to add. Too little and it won’t whiten or disinfect. Too much and it can damage fabric, weaken fibers, and cause yellowing. The right amount depends on the type of bleach and the load size. Here’s how much bleach to add to laundry without damaging the fabric.

Bleach in laundry is a whitening and disinfecting additive. There are two types: oxygen bleach (safe for most fabrics and colors) and chlorine bleach (for white cotton and linen only). The right amount of bleach depends on the type, load size, and purpose. Using too much bleach can damage fabric, weaken fibers, and cause yellowing.

To add bleach to laundry, use 1 scoop of oxygen bleach per normal load or 1/2 cup of chlorine bleach per normal load. Add oxygen bleach to the drum or dispenser, and chlorine bleach to the bleach dispenser. Wash in hot water. Don’t use more than the recommended amount, don’t use chlorine bleach on colors, and don’t mix bleach with vinegar or ammonia.

How Much Oxygen Bleach to Use

Oxygen bleach is safe for most fabrics and colors. It’s the recommended bleach for regular use.

Small load	1/2 scoop	Drum or dispenser
Normal load	1 scoop	Drum or dispenser
Large load	1.5 scoops	Drum or dispenser
Heavy stains	2 scoops	Drum or dispenser

How Much Chlorine Bleach to Use

Small load	1/4 cup	Bleach dispenser
Normal load	1/2 cup	Bleach dispenser

What Not to Do

Don’t use more than the recommended amount. Excess bleach weakens fibers and causes yellowing. Stick to the recommended amounts.

Don’t pour chlorine bleach directly on clothes. Always add it to the bleach dispenser. Direct contact can damage fabric.

Don’t use chlorine bleach on colors. Chlorine bleach strips color. Use oxygen bleach for colored clothes.

Don’t use chlorine bleach on silk or wool. Chlorine bleach destroys protein fibers. Use oxygen bleach instead.

Don’t mix chlorine bleach with vinegar. Mixing them creates toxic chlorine gas.

Don’t mix chlorine bleach with ammonia. Mixing them creates toxic chloramine gas.

Don’t use chlorine bleach on every load. Overuse weakens fibers. Use oxygen bleach for regular whitening and chlorine bleach only for tough stains on white cotton.

Don’t soak clothes in chlorine bleach for more than 15 minutes. Extended soaking weakens fibers.

Don’t use fabric softener with bleach. It coats fibers and reduces bleach effectiveness.

Don’t use hot water with chlorine bleach on protein stains. Hot water sets protein stains. Treat protein stains first, then use bleach.
