I love that stuff! Usually if a speaker is badly scratched, I'll lightly sand it down or rub it down, before using the products. Then wipe with a barely damp cloth.
One of the best product sequences I've found is (1) Watco's Danish Oil ; (2) Howard's Restore-a-Finish; (3) Howard's Feed-N-Wax. For products that come in different wood colors, I suggest using "neutral", or a shade lighter than you want the final color to be; all of them, even the "neutral" ones, contain a bit of pigmentation or at least natural coloring, and will darken the final wood color slightly. Up to a certain point, the more coats you put on, the darker the final finish will be.
For the first coat, apply liberally and rub LIGHTLY with about 400 grit fine sandpaper, WHILE WET with the product; a sort of "slurry" of the oils and sanded wood will fill any gaps in the grain, giving a smoother, glassier final finish. Being careful not to cause scratches, for the first coat you can rub across the grain, to help push the slurry into the gaps. For subsequent rubbings/sandings, go mostly with the grain, but be gentle. Allow each product/coat to sit overnight for settling in/drying. The next day, rub gently, using a non-scratch kitchen pad, then wipe clean with a "tack cloth". You can gently buff with a clean piece of old T-shirt or similar, for an extra-smooth finish. Then do the next coat/repeat the process. One or more coats with each product, in the sequence mentioned above. Don't use sandpaper for the later coats, and use only the cloth for the final Feed-N-Wax coat(s).
I've transformed hopeless-looking, dried-up, scratched, etc... cabinets into things of real beauty, using these products this way. They're great! :yes: :thmbsp:
The only drawback is that it takes time. If you don't let them sit overnight between coats, the results are not as good. In really bad cases, or cases where I really want fantastic results, it can take 10-14 days to finish "transforming" a pair of speakers, but the results are worth it.
Depending on the humidity/air conditions in your area, you'll probably want to "top up" the finish with a little Feed-N-Wax every 6 to 12 months, thereafter.
(Note: brass wool is better than steel wool. Tiny slivers of the wool can break off and become embedded in the wood. Later, the steel slivers may rust and cause brown spots; brass slivers won't.)
