Thanks Ken but the little dots are in the Ebony fret board, they are not the pearl place markers. I will look into the fret board conditioners, that would be good to have on hand.
I have cleaned the dulcimer and it now looks like new. You can see the difference between grimy strum hollow before & updated photo attached.
I lower the action, just a hair to make it easier to play and sing as I slide up the fret board. It is a Prussia Valley Butternut & Walnut 3" deep dulcimer, I knew under the grim it would be beautiful with a full tone - and it is.
Thanks for all your help
Oh, I blacken the 1.5 until I get use to it - it will wear off in no time.
