¡Bueno! While I let my electric guitars "relic" I like my acoustics to stay show room shiny. What sort of treatment if any can I use on nitro to preserve it as it were? Do products like Dr. Ducks Axe Wax/Oil help? Martin recommends it as a safe treatment but I never see any products recommended to keep nitro finishes from checking etc. I use Virtuoso cleaners and polish. Thanks!
