I want to "hydrate" some BRW necks and boards that appear to be drying out. Some have a few white spots...some have "faded" a bit. Most need a bit of "oiling".

Is "Fret Dr" the most popular? I have this stuff already,.....

but I've read on various forums that it's composed of solvents that can damage the Brazilian, so I'm looking for the "good stuff".

What do you folks recommend to keep the Brazilian looking fresh and properly moisturized? Please provide your recommendations as well as any thoughts with regard to which products may actually do more harm than good.
