Instructions for Applying Mineral Oil to a Butcher Block

Treated well, a butcher block can last a long time. But there are some steps you should take to prevent damage or deterioration. Applying mineral oil to a butcher block will prevent it from absorbing odors. It will also ward off stains. Mineral oil is also preferable to other common finishes, such as boiled linseed oil, which can turn rancid. Mineral oil is also preferable to polyurethane because the mineral oil finish can be repaired if the block is damaged.

Things You'll Need

Soft, lint-free rag

Pot, with water.

Instructions

- 1
  Warm the oil slightly to loosen it up (optional). Mineral oil is flammable, so be careful and be sure to keep it away from any flame. The easiest and safest way to to this is to boil two or three inches of water in a pot. Take the pot off the stove, let it cool for a few seconds, and place the container of mineral oil inside the water for a few minutes. Make sure the cap is off because if you heat the air too much there is a chance that the lid will pop off.

  Dip cloth in the oil. Apply mineral oil to the butcher block, rubbing in the direction of the grain. If this is the first time applying oil, apply four of five coats of oil.

  Wait. If this is the first time you are applying mineral oil, allow it to soak in for four to six hours. If you are applying mineral oil for a weekly or monthly maintenance, wait 15 to 20 minutes. After the time has elapsed, wipe away any excess oil. Oil the block monthly, or as needed, such as after a major repair, a major cleaning, or if it has recently been sanded. Do not put a butcher block in the dishwasher.
