I have a couple of basses that look like they could do with an oiling of the fretboard, I know oiling the fretboard too often is a very bad idea so its always a once in a blue moon kind of occurrence for me, however a post by Terry Mcinturff of Mcinturff on another forum (not sure if I am allowed to post the link so I will omit it for now) had me thinking that maybe it is a bad idea to oil a fretboard, specifically the below from his posts ,
"When a fretboard is oiled, it is not possible to prevent that oil from seeping-under the fret.
Especially when using a non-drying oil, this can result in an accumulation of oil under the fret which causes true harm to the guitar.
Here's how:
- Can soften the wood in the vital fret slot region (non-microbial "rot")
- Can provide a microbial environment (oil/substance-dependent), encouraging microbial activity that will actually digest the wood under the fret (microbial "rot")
- Can lessen the fret's "grip" on the wood....frets can pop-up causing buzzing/dead spots
- Can complicate refretting; the wood is infiltrated with oil and fret replacement is compromised/more difficult
5) How do I know if an oil is safe to use on my fretboard?
Wipe a streak of the oil on a pane of glass. If after 3 days it's not hard...or clearly getting hard....use it for something else, or dispose of it. Do NOT use any oil on your fretboard that "stays wet". Ever. If you've been doing-so, stop now for the health of your guitar.
For reasons explained above, any oil that does not dry, which stays wet, is an enemy of the integrity of your guitar. Repeated use of such constitutes harming your guitar."
Interested in hearing what others think about this, the above posts are by someone that builds guitars but I think it would be naïve of me to just assume that because he builds guitars it must therefore be true after all there is a world of BS out there that is perpetuated by "experts" and to me the bit about how its impossible to avoid oil seeping below the frets sounds a bit dubious to me after all most of us use fretboard oils in tiny,tiny amounts
