Detail 01
Bore oil, not key oil
This goes on the inside wood surface. Key oil is a different product for the mechanism pivots and shouldn't be swapped.

Independent shopping perspective
Bore oil for wood-bodied woodwinds. Conditions the interior wood of clarinets and oboes to slow drying and cracking. A maintenance item, not an upgrade.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
This goes on the inside wood surface. Key oil is a different product for the mechanism pivots and shouldn't be swapped.
Detail 02
The bore takes the most moisture from breath. Conditioning it evens moisture exchange so the wood moves less with humidity swings.
Detail 03
Only unfinished or lightly finished wood absorbs it. On plastic it just sits there and migrates onto pads.
Detail 04
You need very little per application. A bottle lasts a long time under normal maintenance intervals.
Detail 05
Excess oil soaks into pads and tone hole seats, which swells and ruins them. Sparing application is the whole technique.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Opinions vary by tech and climate. A few times a year is a common interval; new instruments during break-in get it more often. Ask your repair tech.
No point. Plastic doesn't absorb oil, so it just pools in the bore and eventually reaches the pads.
It helps the wood handle humidity changes more evenly, which is one factor in cracking. It's not a guarantee against it.
No. Bore oil conditions the wood inside the instrument. Key oil lubricates the metal pivots and rods. Keep them separate.
