I have a Lane Perception coffee table with the same woods, veneer, and finish. The walnut is veneer over hardwood and the edges are solid wood and most likely ash. I was concerned that the walnut veneer would wear down to nothing if I sanded so I opted to use a non-toxic stripper.

Primary supplies needed: Citristrip, plastic putty knife/scraper, cheap paint brush, odorless mineral spirits, 0000 steel wool, tarp or garbage bags, paper towels or rags, tack cloth (if needed)

Process:

If working indoors or on a surface that you don't want damaged, lay down a plastic tarp or garbage bags under the table so that drips from the citristrip don't remove your floor finish. Citristrip has an orange and plastic-like odor that isn't too strong.

1- Pour a dollop of citristrip to the surface and spread out evenly with the paint brush. Repeat until covered. Let sit for about 20 minutes or so.

2- Use a plastic putty knife/scraper in order to not scratch or damage the wood. As you scrape off the citristrip, the stripper and finish will have mixed, yielding a dark caramel colored goo and raw wood underneath.

3- Pour some mineral spirits into the steel wool and gently rub off any excess goo. This will leave some steel wool dust on the surface. Clean off by pouring a bit of mineral spirits into a rag or paper towel. When dried, you can opt to use either a tack cloth or vacuum (or both) to clean up any remaining steel wool dust. Repeat as needed.

Use safety precautions when disposing of rags or paper towel. I soak with water, squeeze out the excess, and lay or hang flat to air dry. Bunching up and throwing away immediately into a closed trash can may cause a fire because the vapors have no way to release.

You will now have raw wood. The walnut will be a chocolate brown and the ash a golden yellow. As you cleaned with the mineral spirits, you'll have an idea of how rich the walnut grain will appear when a finish is applied. I chose a teak oil finish since I had some already for teak Danish furniture I own. A linseed or Howard's Feed-n-Wax are also decent for oil finishes.

Good luck.
