Cleaning & polishing premium-grade speakers

What do you use to polish and maintain exotic wood loudspeakers? I have a Crimson Birdseye veneer and I wonder if there is anything I can do to keep the shine as well as protect it. For the meantime, I just buff mine with a cotton shirt. Thanks!
Off I go to Home Depot and find myself some Weimans then. If not, then my kid's pj will do. What do you guys think about sirspeedy's suggestion? I am no wood expert so all your feedback is appreciated...
I too am a custom furniture builder. If the right adhesive and finish are used, there should be no splitting. Finishes from 40 years ago are not as good as today's finishes. There should be absolutely no need to wipe it down with anything other than a dry cloth.

The simply fact is, if the lemon oil is penetrating the wood itself, the finish is not doing it's job.
The most important thing NOT to use is anything citrus based. It will bleach your finish over time.
Horton,can't say I disagree with you.Actually Avalon claims that nothing is necessary.

However,and I'm most likely a bit over the top here,yet my 15 yr old Ascents look EXACTLY like "hour one",with all the crap floating around in the air,as well as household pollutants,it seems like "not too big a stretch" to give a nice protective coating once every 3 months ago.A good cardio workout as well. -:)

As a professional restorer/conservator I concur with S7horton's comments on this matter. Moisture has no place in solid or wood veneer. In fact, one reason that clear coat finishes are applied in the first place is to keep moisture out. Clear coat finishes do not soak in oils or waxes either, all of that stuff stays on top of the finish. The best thing one can do to keep your wood items looking new is to keep them away from sunlight and heat. Dusting with a clean, soft slightly damp cloth as all that is needed.

As for lemon oil products, they are an oily petroleum distillate with a lemon scent added. They will add a temporary shine, but that's it.
