Have you ever thought about what soap is? This slippery, sudsy stuff we use every day does its job without us thinking much about it. We know it makes the world cleaner but do you know what makes soap soap? If you want to explore these questions, we invite you to check out "Exploration Clean". Exploration Clean is an Interactive Online Resource to help students (and…
Q: Will a bar of soap last longer if you let it air out or if you keep it closed up in a soap dish with a lid?
A: It's preferable to let it air out. If you keep your bar soap in a closed container, the soap will stay wet. As a result, it can become mushy and dissolve quicker.
Handwashing is one of the most effective things you can do to protect your health and the health of those around you. All soap helps — but in some situations, antibacterial soap can go a step further. Understand its benefits, how it works, and when to use it.

How does odor neutralization work and how is it different from fragrance?
Great question! We asked Sammy Wang, MSE, a senior scientist at Procter & Gamble and here's what she told us:
Odor neutralization works by essentially reducing bad scent, which typically involves modifying odor compounds so they no longer smell bad. This can be accomplished in different ways – for example, by trapping the odor, by changing the odor’s chemistry, or by breaking it…
What’s the science behind how cleaning products remove dirt and bacteria?Cleaning products work by leveraging chemistry and biology to break down, lift, and eliminate unwanted substances from surfaces. Most cleaning agents contain active ingredients—such as surfactants, enzymes, or disinfectants—that target specific types of dirt and microorganisms.Surfactants are molecules that reduce surface tension, allowing water to spread and penetrate grime. They surround and loosen…
There's lots to teach about cleaning! The origins of personal cleanliness date back to prehistoric times. Since water is essential for life, the earliest people lived near water and knew something about its cleansing properties - at least that it rinsed mud off their hands. And clean hands keep you from sharing germs. Browse ACI's publications for teacher resources.

Grout is generally porous and white or light colored and can get dirty or discolored quickly. Get it clean with a little chemistry and a bit of elbow grease.
First off, you'll want to use an alkaline cleaner. Grout is primarily cement and can be dissolved by acids. Over time, an acidic cleaner may require you to re-grout sooner than intended.
How do you know if your cleaner will do the trick? Typically the product label will tell you the surfaces it works on. Or, if it…
Frequently cleaning your hands can slow the spread of germs. Alcohol based hand sanitizers or gels or antibacterial wipes are useful alternatives if soap and water are not available (for example, when traveling in the car or taxi on the way to a business meeting, before eating an in-flight meal or snack, outdoor work settings, etc.)
When Soap & Water are not Available - Use Hand Sanitizer or Hand Wipes
Use one or two squirts or pumps of the product…
