I am about to change the strings on my DiPinto Belvedere std. I was going to soak the current strings & try them a little bit longer first... or in case I don't like the flats I bought for it. I am not sure what kind of strings are on the bass (it came with them) but, they have a red, cloth winding at the ends. Will the alcohol hurt this cloth? Will it eat away the cloth & lead to the strings unwinding?
