Lapella No.33 Fingerboard Oil

I have two ebony fingerboards: on my 150 y.o. violin and on my 140 y.o. 7-string guitar. Their boards get dirty much faster than other boards made of woods. Because of their fine grain one notices the dirt immediately. Lapella oil cleans beautifully. I leave it overnight for the deep cleaning effect. Totally worth it! The company are masters of care for delicate classical instruments. I'm allergic to perfumes, but appreciate Lapella's gentle lemony fragrance.

It cleaned the fretboard without any issues, and it got sucked into the wood relatively quickly. It took like 14-16 hours. Others can take up to 24+ hours
