Hey there! Using Schmere Dirtbags is easy. Just grab one and use it on your clothing or other non - skin contact stuff. They come in four cool colors. But here are some important things to note. First, never use them on your skin. Second, make sure you're in an open space or a well - ventilated area because you shouldn't inhale. If you're the one applying it, put on a safety mask and gloves. Also, don't go overboard and use too much. As for maintenance, keep them in a dry place when not in use. That's it, and enjoy cleaning the clean way!
