Bleach is a disinfectant that’s been around for almost a hundred years, but that aside there are lots of problems with using bleach.
First it’s not an effective cleaner, so you’ll need to use something else to perform that task. It also comes with very slow contact times (amount of time a surface must stay wet to kill germs) and who has time for that in a busy salon?
Finally, it is irritating to skin, eyes and breathing it in all day long isn’t great for your lungs. If there’s a faster, cleaner, safer more user-friendly alternative, why not use Rejuvenate instead?
