Cleaning & polishing premium-grade speakers

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.

All polishes and waxes are a joke if you think they are going to feed the finish, moisturize the wood, save the finish from checking, protect the finish from water, solvents, oxidation, light, heat or chemicals. They can not and do not do any of those things.

What polishes and waxes will do is help with scratch resistance, will add a temporary shine, can leave a pleasant scent in the room, can aid in dusting and will take money out of your wallet to feed the million dollar polish/wax industry.

Armor All on furniture!?! That's a first for me and I thought I'd heard/seen it all.
