Clorox bleach is an inexpensive weapon in the fight to keep your garden weed free. You might already know that bleach has more uses than making your whites clean, but did you know that Clorox is a weed killer? You can save money by using this common household chemical to kill weeds.


Place Clorox bleach in a spray bottle and spritz on the weed you want to kill. Bleach will damage any plant that it touches, so be careful to only spray the plant you want to remove. Be sure to spray the leaves and base of the weed so bleach gets into the roots.

Time Frame

Clorox bleach will kill a weed in about two days. This is also the amount of time it takes for the bleach to evaporate from the surrounding area. Do not try to replant the area you sprayed with Clorox before then.


Wear gloves and old clothes when working with Clorox as a weed killer. Bleach can irritate your skin and cause white spots in your clothes.


Clorox bleach works slowly to kill weeds. If bleach accidentally spills on a desirable plant, use a hose to wash the chemical from the leaves and soil surrounding the plant.


Clorox bleach is a good choice for killing weeds that grow in the cracks of a sidewalk, driveway or patio. Because here is no worry about saving desirable plants close by, you don't need to worry about bleach overspray damaging neighboring plants.


Bleach is a dangerous chemical when abused and could contaminate the soil or ground water if used in excessive amounts. It has a pH of 11 which could raise the pH levels of your soil. Use bleach sparingly to kill weeds.
