GHS Fast Fret

I have been using Fast Fret for years now. It keeps my strings from drying out and helps me slide easily along the strings as well as feel slicker which makes it easier for me to play. It is also possible to use it after you finish playing to wipe off all the ?dirt? from fingers. Simple chemistry, as I would say. In my opinion this is the best string cleaner I have ever used. It includes the applicator and a cloth to wipe off the excess oil which both fit in a small plastic tube that can easily fit in a guitar case pocket. I really like that it lasts a long time. I have had my previous one that I use for 2-3 times a week for about two years in a row. So I think that this is great thing for its money. Just imagine ? one can for 2 years or even more!
I use it for my basses and guitar. And it perfectly works regardless material of strings (tried with nickel, chrome and steel) and roundwound of flatwound. Great thing is that it does not affect fretboard material ? maple, rosewood, ebony? It makes it in good shape anyways. So you may no worries for your oiled maple fretboard.
I found it a bit easier to use than cleaner by Dunlop because the applicator stays wet for all time, no need to shake as with Dunlop bottle.
It is definitely not the thing that make strings last forever, but it can helps out for gig or some demo recording if you need strings to sounds almost like new.
