Not only will it absorb odors it will allow lots of thing to pass. Look at the spot on used gibbos where your arm rests across the top of the body. Skin chemicals,acids, sweat, can quickly make a disfigured area on the finish and theres really nothing you can do about it.

The OP's discoloration started from the bad rubber on the surface of the lacquer ( which had a chemical reaction to the lacquer ) and then went through it. It will absorb stains as well as odors. Any guitar that "yellows" with age is lacquered. Remember lacquer is made from cotton dissolved in nitric and sulfuric acids then liquified with fast drying solvents. Your ax is basically covered in chemically recomposed organic matter and it is quite delicate, and WILL negatively react to different chemicals or substances.

If you dont want the dissapointment of finish problems such as the kind that occur with lacquer (checking, discoloration, ect) i would strongly reccomend guitars finished in polyester.

Make sure you know the finish first before you a apply a solution.

As for me, I'll finish mine in nitrocellulose lacquer, and I like checking as long as it's natural.

So let me ask you one then, why would a nitro finished guitar retain residual smoke odor while a poly finished guitar used in the same enviroment for an equal ammount of time not have a residual smoke odor?

Knowing what it's made with is key if the OP plans on applying a chemical cleaner, what may work on Poly may mess up Nitro and vise versa...
