We assume you know how to use toilet paper and really don't want us to elaborate. 🧻 Thus, when you're 'done' on the toilet, use dry paper once like normal. (Skip the "dry" step if wiping the front side.)
Then scrunch or fold fresh toilet paper, press it into The UnWipe's mesh for just ½ second, and use again like normal. Repeat until clean – cleaner than from dry toilet paper alone. But really, it's much more fun to watch Logan explain.
