Has anyone tried the “Bore Doctor” bore oil offered here:
http://www.beafifer.com/boredoctor.htm
and would be willing to comment on its quality?
thanks!
Unfortunately, that advertisment doesn’t really say too much about the product. There’s no usable description and it amounts to little more than the testimony of the inventor.
I’m a little concerned that a PhD would talk about ‘nourishing’ dead plant materials (such as the wood of your flute which has been dead long before you bought it), but that’s a pretty common phrase, so I’ll let it pass.
A common use of the term ‘bore oil’ describes mineral oil used for musical instruments. The description does not suggest that this is ‘bore oil’ in that usage, but some mixture of plant oils.
None of that means it’s a bad product, I just wish they would give more useful information in their ad.
I dislike mineral oil for flutes. I felt it clogged up the bore. It made my flute feel heavy. I much prefer a vegetable oil, thinly applied.
A non-technical answer. I’ve been using it and like it. It is a bit expensive, though.
There’s more information here:
I use it too. You only apply a tiny bit, it penetrates quickly and seems quite protective. I’ve never noticed any “build-up” from it, like I have with other oils I’ve used. I’ve never been quite as thrilled with almond or linseed oils.

Really good stuff. Works like a charm 
i absolutely love his natural cork grease-------doctor slick
Me too, the best I’ve used.
I started using his products on my clarinet, a 1950 Selmer, and it works beautifully. The bore oil, the corkgrease and his swab all work better than any I have tried.

Have been using the cork grease (Dr. Slick) for several years, and my cork (on a saxophone neck) is nearly like new. The fellow who makes these products seems to really know what he’s doing.
