Hi Guys, I am really thankful to all the members who help beginners with all guitar related issues on IindianGuitarTabs. I had purchased black Pluto Guitar HW41C - 201BK guitar in April 2010. I am beginner and I occasionally play guitar or rather I try to play guitar My problem is the strings of my guitar look old and have darkened in such short time. I do clean them with dry cloth on every alternate day. when I see fellow students in my music class with Granada guitar their guitar look very fresh and their guitar strings have their original shine. Is it same with other people who using pluto guitar???
