Big Bends Gem Tone Wipes 25

I bought these because I was fed up with my fingers pickup all the grime from the strings. They certainly remove the grime and may over time extend the life of the strings.
A longer term test may be needed to ascertain if they do indeed extend the string life.
The treatment on the wipes smells quite strong. I am a bit worried it could damage a guitars finish etc.
I will continue to use until I have used all the wipes but I may try to find an alternative solution in the long term.
