Houston, we have a problem. My girls had a humidifier in their room this winter and their beautiful roman shades have stayed down. My initial thought was that this was a great way to add a little extra insulation to our poorly insulated house. Well, it backfired. Big time. When the girls went to raise their blinds, we discovered that the windows had collected moisture, and now there is mold all over the windows, blinds and window panes. Since we are heading out of town, I thought I’d take care of the problem with some bleach before we left so that their room would have some time to air out, but in the back of my mind, I remembered something I had read about bleach being not so great for us. So, it is time to explore the scoop behind bleach and it’s effects and decide what to use to kill the mold.
What’s the Difference between Chlorine and Bleach?
Bleach is any chemical used to lighten or remove color. So, based on this definition sunlight and lemon juice are also bleaches. Chlorine was used in the past as the main ingredient of most household cleaning bleaches. Here is where it gets vastly confusing for those of us who aren’t chemists. According to the NY State Department, chlorine is formed by the electrolysis of sodium chloride brine. Sodium chloride is salt. Brine is salt water. My friend google tells me that electrolysis is, “Chemical decomposition produced by passing an electric current through a liquid or solution containing ions.” So, it sounds like they are talking some salt water and sending an electrical charge through it thus decomposing it and changing the cellular structure of the solution. Are you still with me?
The leading maker of what I think of when you say “bleach” is Clorox. The ingredient list on their bleach includes sodium chloride and water amongst other things. Does it have to be listed as chlorine if you put an electrical charge through it, or is it possible to list chlorine as their parts instead of what they are post-electrolysis? Probing a little further though, their corporate website says this, “In 2011, Clorox completed its transition of all U.S. bleach manufacturing operations from using chlorine to high-strength bleach as a raw material. The transportation of chlorine has now been eliminated from our end-to-end U.S. supply chain.” Which would lead you to believe that it doesn’t contain chlorine at all, right? Well, then on another link from Clorox’s site, I found this description of their bleach, “This product is a 6.0% sodium hypochlorite solution, containing approximately 5.7% available chlorine by weight. The purity of its ingredients and the carefully supervised process of its manufacture make this product a quality source of chlorine for water treatment in swimming and wading pools.” So the product that doesn’t contain chlorine is apparently a quality source of chlorine. Yep, that doesn’t make any sense at all! I personally, am going to err on the side of caution and assume that if their product is a quality source of chlorine, that it must contain some chlorine.
Dangers of Chlorine
There are long lists everywhere on the hazards of chlorine to our health. My favorite fact on why we should avoid it is from the New York State Department of Health: “Chlorine was also the first poison gas to be used as a weapon during World War I.” They go on to share that chlorine destroys cell structures and can result in pulmonary edema. Another source shared this tidbit, “When mixed with ammonia, it [chlorine] creates a deadly gas. Remember that urine contains ammonia, so using the products in the toilet increase the risk of creating a toxic gas that can actually stop lung function.” Mercy. According to the NY State Department, even if it isn’t mixed with ammonia, just inhaling chlorine (which is where you are most likely to be exposed since at room temperature, chlorine is a gas) can result in, “eye/skin/airway irritation, sore throat and cough…At higher levels of exposure, signs and symptoms may progress to chest tightness, wheezing, dyspnea, and bronchospasm.” (Fyi, dyspnea is shortness of breath and bronchospasm is a tightening of the muscles of the bronchioles and is often related to asthma.) They also go on to share a larger concern for our little munchkins who are no doubt running around the house as we clean. “Children may receive a larger dose than adults exposed to environments with the same levels of chlorine gas because they have greater lung surface area-to-body weight ratios and increased minute volumes-to-weight ratios. In addition, they may be exposed to higher levels than adults in the same location because of their shorter height and the higher levels of chlorine gas that may be found nearer the ground.” So chlorine hangs around nearer the ground where my munchkins are hanging out, breathing deep. Good to know.
Regardless of whether or not bleach actually contains chlorine, the warning label alone should be a heads up: “Danger: Corrosive. May cause severe skin and eye irritation or chemical burns to broken skin. Causes eye damage. Wear safety glasses and rubber gloves when handling this product. Wash after handling. Avoid breathing vapors. Vacate poorly ventilated areas as soon as possible. Do not return until strong odors have dissipated.” I don’t know about you, but I haven’t been pulling out my safety glasses and rubber gloves when using bleach. Also, I’ve just discovered that bleach isn’t the best at cleaning mold on porous surfaces. A source said this, “Some of the mold on the surface might be killed but the roots of the mold are left intact meaning the mold soon returns, leaving you in a cycle of repeated bleaching. Perhaps this is why some people believe that spraying bleach on mold doesn’t affect it but instead just bleaches its color so you can no longer see it.” I think I’ve learned all I need to know. It’s time to look for an alternative to eliminating the mold in my girlies’ room.
Next week, we’ll look at alternatives to bleach for killing mold. For now, have you ever experienced negative side affects from using bleach or chlorine? Or, if you are a chemist, feel free to enlighten us where my understanding is limited!
