Purchase a 100 percent walnut oil product if applying to a food preparation area. Some impure solutions may introduce potentially toxic chemicals, but pure walnut oil is non-toxic.
Apply liberal amounts of walnut oil over the area to be finished. Use a rag for small areas or a roller for large areas.
Allow the walnut oil to absorb into the wood for approximately 30 minutes.
Wipe off any remaining walnut oil, using a clean rag along the direction of the grain.
Repeat the procedure for a second coat, if desired. Walnut oil is non-curing, so one or two coats will be sufficient.
- You can also use a mixture of walnut oil and beeswax for a more protective, all-natural finish.
