It's not going to be sticky forever, but you can work on about 2 weeks or more of some good sticking action. And even then this is wholly dependent on how dirty the stuff you're putting on there is, as the sticky surface will naturally attract dust and debris. When this happens though, simply take a wet cloth and wipe it down to restore it to its former sticky glory. Washing it with a little warm soapy water will really do the trick as well.
