Mark, Boston uses an "approved" grease on their unwound stringing destined for wetter climates. Piano voicing can redistribute this a little and it tends to collect hammer felt and dust. I personally recommend using Edwards StringCovers. The felt prevents condensation and buffers humidity. Combined with a DC and undercover the whole piano is well protected.
