Maybe those [color=#282828][font=helvetica, arial, sans-serif]shiny marks are just[/font][/color] accumulated grime and the lemon oil wont help.
Since we´re talking about an oil based finish instrument, i would use spirit of turpentine.
Spirit of turpentine is a suitable product for cleaning wood and, unlike mineral solvents, will not cause it to dry out.
Moisten a clean, dry cloth with a little bit of solvent and then gently rub those spots. Let it dry for about 10m. After that you can use your warwick wax to bring back that satin finish.
Hope this will help
