Sticking with mineral or walnut oil is the best option as you condition your counters immediately after install. Other oils are not food safe and could be very unhealthy if they were to leach from your counters into the food you are preparing. Vegetable oils will look and work fine at first, but will ultimately turn rancid. The benefit of these oils is they're food safe and they won't go rancid. Instead of mineral oil, if you want something that will dry and harden a bit as you continue applications, you can use walnut oil. No special brands, no linseed oil infused items, nothing that boasts penetrating formulas or additives that cause hardening over time, no "mystery" ingredients, just food safe mineral oil. Cleaning products also do not get into the wood, instead just cleaning the essentially solid surface. Water could no longer penetrate the surface and would simply bead up when applied. Ultimately, the butcher block surface would become so saturated with the animal oils that it wouldn't and couldn't possibly absorb anything else. As the butcher's would work on the blocks, the fats and grease from their work would saturate the work area, and the wood would absorb it like a sponge. They were installed untreated and put to use. The meat cutting and prep areas were adorned with the heavy and solid wood blocks. But what should we use to protect it?īutcher block, as their name implies, was made popular in butchers' shops. So it becomes our mission to protect ourselves from an unsightly and unhealthy counter top by first protecting the counter top from the possible contaminants. Each item can contribute to the drying, aging, and cracking process they is inevitable in wood, as well as the possibility of contamination. Now that it's installed in our house, as an untreated surface the butcher block is eager to absorb anything we lay on it, including water, vegetables, fats and oils, dirt, wine or whatever else happens to come in contact with it.
