This is unacceptable by my standards; absolutely unattended fretboard with lots of gunk, fungal infection & that white residue there- I suspect it's dry polish cream (to polish the frets).
This is how my Ibanez VJ50 looks like after treatment:
- Strings were replaced
- The first thing I did to the fretboard was to clean it. I used an alcohol-based fretboard cleaner because alcohol dissolves dirt very effectively. Alcohol is also a fantastic dislodging unit so for those stubborn dirt there, they were dislodged. Alcohol dries up easily- this is a very important consideration for me so no residue lingers at the applied area.
- However, alcohol dries your porous fretboard so the next thing to do, naturally, was to recondition the fretboard. I was patient with this as the fretboard was evidently very dry, some areas at the lower frets showed signs of flaking off.
