The following request is made with due respect toward smokers. I am greatly sensitive to residual cigarette chemicals. As my recently acquired CS 257 (bowl-type) Ovation has a great amount of cigarette stench, I would appreciate any feedback on removing cigarette chemicals since this greatly causes my eyes to water when playing. The case was severely ingrained with brown tar, so I purchased a new one. The guitar is in fine condition in terms of no signs of staining, just residual stench. I thought to ask the luthier community before using the Dunlop polish and wax kit I purchased that is said to remove cigarette smoke; I also have Dunlop's lemon fret-board lemon oil. I have never done a thorough cleaning of an instrument, much less an electric/acoustic, so I would appreciate any general advice cleaning as well as removing cigarette stench. (I have not placed the instrument in the new case so that the cigarette chemicals are not transferred.) As a note, I read from an Ovation manual that guitar polish can be used on the bowl; however, I presume it wise to not use it internally since there are electronics though I might be able to do a careful inside cleaning, too. Thank for review and sharing of experience in removing cigarette stench--Jeffrey.
