If we had a pound for every string-cleaning product available today we'd be able to buy, well… quite a few sets of new strings.
This latest system in both guitar and bass versions is quite a magnanimous gesture from the UK's top string-maker, Rotosound, who you might have thought wouldn't want us to extend the life of our strings so we buy more! Indeed, it claims to "revitalise used, old and damaged strings" and to "extend the life and preserves the tone of guitar strings".
The device is simple enough. Two micro-fibre pads are fixed to a credit card-sized, hinged two-piece plastic assembly. You unclip the two pads, slide under your strings, clip back together and then run it up and down your strings, which it is claimed "provides 360 degrees of string cleaning action".
Rotosound says there's no solution needed for this system - unlike the majority of other systems - so in reality, it's not the best to clean really gunked up strings days after your last gig.
Used directly after playing, however, or on strings that have had a little use, yes, it cleans them nicely. But then again, so would a quick rub with any clean dry cloth, wouldn't it?
