Should I Use Bleach on Mold?

This is a question that mold experts get asked frequently and the answer changes based on who you ask. What you need to know is that yes, bleach will kill mold, but not on all surfaces. Other cleaners work a lot better than bleach does when it comes to killing mold, you just have to know what to look for when you’re shopping at your local home improvement store.

Bleach Kills Mold Sometimes

The fact of the matter is, bleach will sometimes kill mold, not all the time. Because of this, you should really not rely on bleach to kill off mold spores in your home. Bleach is great for tiles, glass, bathtubs, or counter tops but it really fails at getting mold out of things like wood, grout, drywall, and other porous materials. Bleach won’t penetrate deeply enough into these materials to efficiently kill off all of the mold. It will return time and time again until it is properly removed at the root.

Bleach is Toxic

Remember that even when using bleach it can be extremely dangerous to inhale. If you decide to try and use bleach you must open up all the windows in the room and have a fan going to blow the toxic air from the bleach out of the room. If you do this it will at least lower the damage you will cause to yourself from breathing in the fumes.

Using Bleach and Calling Professionals

We recommend that instead of using bleach you try a mold killer and mold protector that you can buy from your local home improvement store. This two things will kill off the mold and prevent it from returning. If these two products fail to keep the mold away, then it is time to call a professional company like Water Damage Zone. Companies like ours will go above and beyond at inspecting your residence for any mold infestation and completely treating it from beginning to end so that it does not return.
