Planet Waves Renew String Cleaning System  

I found the Renew very easy to use and far more effective than any microfiber or cotton cloth, neither of which can apply as much cleaning pressure as I can get with the renew.  The harder I try to clean, dirty strings slice and cut right through cotton and especially microfiber cloth which is why I tried the renew in the first place.  The pads on the renew are pretty indestructible and work both; with and without the cleaning solution.

Not that instructions were necessary but Planet Waves suggests loosening the strings to ease with cleaning which I do on my acoustics (this also helps me clean up to and past the nut).  My electrics are all lock-nut equipped so, I just depress the bar to loosen the strings and wipe them clean in a few passes.  Seriously, changing strings on lock-nut systems is a pain, and for that alone the renew is priceless to me.  Strings stay new looking, sounding and playing. I love it

virtually indestructible...long lasting pads

I paid less for the renew than I do for a pack of strings and 2 cleaners were included.  

FINALLY, something that works.  Out of necessity, I've used rags to 'clean' my strings for most of my playing career but have always searched for anything that would more effective remove tarnish and build up. I've found that most of the string cleaners available are really more string 'wipers' than they are string cleaners. In other words, they merely wipe the sweat and oils off of new strings.  If that's all you need or want, then save yourself some money and use a bandana.  However, if you don't change your strings once every week or two then you should try this renew cleaner...it actually removes the tarnish NOTICEABLY better than any other product out there.
