Cleaning, polishing Speaker Cabinets ?

I use a citrus based cleaner, then apply bees wax and buff to a nice shine. I find that using a soft dust cloth for the final buffing brings the bees wax to a gloss. Then I check by rubbing my fingertip on the finish to assure all the wax has been polished in. If is see my fingers smudge, that indicates there is still too much wax that hasn't fully polished into the wood. Time consuming but a light dusting when cleaning house with the same soft dust cloth maintains that shine.

As Bill_K says, there is no one product right for all finishes. Currently, most wood veneer finishes are over coated with a catalyzed clear coat that is not going to allow any product to pass through to the wood underneath. So, waxes or automotive type products are going to work fine for clear coated veneer or lacquer surfaces. Most of the time, those oil based wood care products do no good whatsoever. In the rare event you have an open grain or oil finish over wood veneer, then one of the oil based products will actually work.

I have Vandersteen 5A's...the recommendation is Pledge. I know this sounds like an anathema to those that love wood finish, but there is a very thick urethane coating on the speakers so I just need to clean the surface. I have the Kowazinga option which is gorgeous. I had a furniture man at the house to touch up some end tables et al, and he remarked at the very high quality of the 5A construction and finish.

Fender Guitars markets several products designed to care for wooden musical instruments, making them excellent for speaker finishes. You can find them at most instrument stores like Guitar Center or Musicians Friend.

As important as the polish or cleaner you use is the applicator. Guitar shops also sell super soft microfiber cloths designed to work well on polished wood without leaving any swirl marks.

Yep, I second Tis49; Orange Oil on my Sonus Faber Walnut cabinets. Great results and requires absolutely no skill in the application.
