What is Butcher Block Sealer?
We don’t want to get ahead of ourselves, so let’s back up and talk about what butcher block sealer is. Butcher block sealer can either be an oil or wax that won’t spoil, such as mineral oil or beeswax. These nonperishable oils or waxes are rubbed into the surfaces of butcher blocks to strengthen the wood.
Why Do You Need Butcher Block Sealer?
Butcher block sealer is oh-so-important! Why? Here are some of the main reasons:
- The wood will dry out without sealer
- Sealer keeps bacteria from penetrating below the surface of the wood
- Sealer prevents butcher block wood from absorbing moisture
- Sealer keeps mold from being able to grow within the wood
- Sealer keeps the wood looking glossy and stylish
- Sealer can help keep your butcher block in prime condition for decades

How to Use Butcher Block Sealer
Using butcher block sealer is super simple! All you’ll need is a great butcher block sealer and paper towels. We’ll tell you how it’s done in the steps below.
Step 1-Choosing the Right Butcher Block Sealer
If you’re looking for a high-quality butcher block sealer, then we recommend choosing 1 of the 6 sealers we’re going to discuss later in the article. If you prefer, you can also choose to use beeswax or food grade mineral oil.
Step 2-Cleaning Your Butcher Block
When you notice your butcher block’s wood isn’t as glossy as it used to be, it’s time to seal the wood. Before you begin, handwash your butcher block with warm water and gentle dish soap, while never fully submerging the board under the water. Also, do not put your butcher block in the dishwasher. Once washed, let your butcher block airdry completely by standing it up on one side against a wall.
Step 3-Spreading the Sealer
Once you know your butcher block is completely dry, you can take your butcher block sealer of choice and liberally pour or spread it on the wood. Using a dry paper towel, rub the oil or wax into the wood in the direction of the wood’s grain.
Step 4-The Waiting Game
Once your butcher block is entirely coated, let it sit with the oil or wax for 15 minutes. Letting it sit allows the wood to soak up the oil, which will make it glossy once again.
Step 5-Catching the Excess
After 15 minutes are up, you’re going to need some more dry paper towels. Wipe off any excess oil or wax on the butcher block with paper towels.
Step 6-Let it Rest
Lastly, let your butcher block rest for the next 2 days. Letting it rest for the next 2 days without using it will ensure your butcher block has entirely absorbed the oil or wax it needs to maintain the strength of the wood.
How Often Do You Need to Seal Your Butcher Block?
How often you need to seal your butcher block is dependent on how often you use it. Are you an avid home cook who chops meat on your butcher block 1-2 times a day? You may need to seal the wood every couple of months. Do you only use your butcher block a few times a week, or a few times a month? You could seal your block every quarter of a year, or even half a year.
The best indicator of when you need to seal your butcher block is the dryness of the wood. If the wood is dry, it won’t be shiny anymore like when you pulled it out of the box. When the wood loses its glossy sheen, it’s time to wash your butcher block and seal it.
What Happens if I Don’t Seal My Butcher Block?
You put your butcher block at risk of growing mold or harboring bacteria and foodborne illnesses if you don’t seal it. How does this happen, exactly? Here’s a quick chart to explain.

Types of Butcher Block Sealers
Not all types of waxes and oils can be used as butcher block sealers. We repeat: NOT ALL TYPES OF WAXES AND OILS CAN BE USED AS BUTCHER BLOCK SEALERS.
Popular oils around the kitchen, such as olive oil and vegetable oil, will go rancid and can make your butcher block unusable. To make sure you’re in the know about which kinds of oils and waxes are good for sealing butcher blocks, we’ve compiled a quick guide below.
Mineral Oil
Mineral oil, or more specifically, food grade mineral oil, is an amazing butcher block sealer. Mineral oil, unlike other popular cooking oils that come from perishable foods, will not go rancid and damage your butcher block. Conveniently, food grade mineral oil can be bought in most grocery stores.
Beeswax
Beeswax is another top choice for a butcher block sealer. Beeswax won’t go rancid, it’s inexpensive, and you can buy beeswax in tons of stores. For an all-natural sealer, beeswax is a perfect choice.
Specially Formulated Oil
The power of science can do what plain mineral oil and beeswax cannot. By buying specially formulated butcher block sealers, you’re giving your butcher block a formula specifically created to strengthen wood. Out of the 3 options, we recommend a specially formulated sealer the most.
