Does Clorox work in cold water?
Yes, Clorox® Regular Bleach2 is effective in all different temperatures of wash water, including cold. Reducing wash temperature is a great way to save energy and important for protecting our planet, but it’s important to note that there is also a performance trade off. Lower wash temperatures aren’t as effective at cleaning as higher wash temperatures, and adding bleach along with your regular detergent is a great way to improve cleaning and whitening when washing in cold water. Adjusting load sizes, pre-dissolving detergent, pre-treating stains, and even spiking cold water with a little hot are all techniques to get better cold water results and save energy. Also, it is particularly important when washing in cold water to not under-use bleach or other laundry products. Doing so will make it even more challenging to get good results than it already is just from the drop in performance that comes with lower wash temperatures.
