These woods include: walnut, oak, cherry, maple, mahogany, elm, cedar, padauk (African), and purpleheart (South American). No stains or dyes are used, only the natural colors of the wood. Mineral oil is used on the cutting boards and trivets and is safe to cut on. Conversion varnish is applied to all other pieces to ensure a durable and moisture resistant finish. Cutting boards and trivets need to be reconditioned a few times a year, depending on use, you may need to apply mineral oil once a month. When the wood looks dry, after several weeks of use, it's time to apply more mineral oil: Make sure the board is clean, place a quarter sized drop of mineral oil onto the surface of the board, rub the oil into the wood grain (a circular motion works best), Let the board sit for 12 24 hours , re apply a second coat, then let it sit for an additional 12 24 hours, wipe off any excess oil with a clean rag.
