A simple tool for keeping the fret of your guitar clean
Guitars when used often will accumulate with dirt, especially on the underside of the strings and onto the fret. Even if sat unused, dust in the surrounding air will slowly gather onto the fret.
If you want to clean the fret of the guitar, you can use a tissue but this process is painfully difficult, messy and aggravating. The other alternative is de-stringing the guitar which is effective but more work than is necessary.
