When it comes to the actual volume of cleaning ingredients you’ll find in your everyday household cleansers, there’s not a lot to them. Most of what you’ll find inside the plastic container is water, which will likely make you question why you need all that packaging in the first place.

Luckily, there are a few brands that will ship you concentrated versions of these cleaners so that you can drop them in a spray bottle and add the water yourself—but guess what? A lot of those refills still come in plastic.
