Frequently Asked Questions

Taking proper care of your John Boos products can ensure that they maintain the level of beauty and durability synonymous with the John Boos brand. Below are answers to some of the questions we hear most frequently regarding proper John Boos product care.

Cutting Boards

Although Boos ® Hard Rock Natural Maple cutting boards DO NOT harbor bacteria, it is a good habit to use separate cutting boards for different types of food prep. For example, use one for raw meat, poultry, or fish, and another for cooked or ready-to-eat foods such as salad, vegetables, and breads. This will ensure protection against cross contamination and will prevent the spreading of certain food borne bacteria such as E-Coli.

A scientific study conducted by Dr. Dean Cliver, Ph.D has proved that maple cutting boards inhibit bacteria growth, while plastic boards have been scientifically proven to harbor bacteria inside the cut grooves. Also wood cutting boards are known to be easier on your expensive knife blades. Click Here to read more on Dr. Dean Cliver’s study.

Sprinkle kosher or table salt on your cutting board and then use a damp sponge or paper towel to rub the stained or discolored area. The salt will absorb stains, flavors, and odors. For stubborn stains, try sanding down the area with a fine grit sand paper. It is very important to sand with the grain of the wood, never against the grain. This sanding process exposes a brand new wood work surface. Once sanding is complete, it is recommended to oil your cutting board with John Boos ® Mystery Oil and/or Boos Block ® Board Cream with Beeswax. This product protects the board and controls its moisture content, keeping it from drying out, cracking or splitting.

Lemon or lime juice with a little salt will go a long way to reducing odor. Sprinkle your Boos ® cutting board with kosher or table salt. Cut a lemon or lime into quarters and use these quarters to rub the salt into the board, squeezing juice onto the board as you go. Let sit for 2-3 minutes and then wipe the cutting board clean with a damp cloth. Use a clean paper towel to remove excess water or let the board air dry by standing it on end.

Store your wood cutting board on end to dry if it is damp. If your cutting board is already dry, store it flat in a dry area away from extreme hot or cold temperatures.

We always recommend using both Mystery Oil and Board Cream but the Mystery Oil is always recommended to be used first. The Mystery Oil penetrates deeply through the wood fibers and while the Board Cream is a denser, thicker formula that protects the top layer of the wood surface. Using both care and mainteance products will prolong the life of your Boos Block cutting board.
• Boos Block® Mystery Oil is a NSF certified food-grade oil that easily absorbs and penetrates deeply into the grain of the wood to help protect, revitalize, and moisturize the wood fibers.
• Boos Block® Board Cream contains all natural, unbleached beeswax and food-grade oil formula. Board Cream is denser, thicker which gives a protective top layer to the wood surface against foods and liquids. It helps keep the water out and the oil in.

A minimum of once a month (depending upon the use and household conditions), apply an even coat of Boos® Mystery Oil to all surfaces of your wood cutting board using a cloth or disposable towel. Allow the Mystery Oil to fully penetrate through the wood fibers overnight, then wipe off any excess oil. Apply additional oil to any visible dry spots or for any other necessary reasons. For additional protection, it is recommended to use Boos Block® Board Cream to seal the top of the wood surface in conjunction to the Mystery Oil. Apply an even coat of the Board Cream using a cloth or disposable towel. Allow the Board Cream to penetrate the wood surface overnight, then wipe off any excess cream. Our Boos Block cutting boards ship from the factory with a Boos Block ® Cream Finish (with Beeswax). When the cutting board becomes dry and lighter in color, you know that the time has come to re-oil your board. NOTE: Use only John Boos ® Mystery Oil or Boos Block ® Cream when oiling your cutting board. An quick alternative would be to use mineral oil only. DO NOT USE ANY TYPE OF COOKING OIL ON YOUR WOOD CUTTING BOARDS. THIS WILL DAMAGE YOUR BOARDS. With a minimum amount of care and maintenance, you can lengthen the life of your Boos ® Board by many years. To see the instructional video, visit our YouTube Channel.

End Grain Cutting Boards features the end pieces of wood rails approximately 1-1/2″ x 1-3/4″ that are glued together into a traditional square pattern. During cutting or chopping, the end grain wood fibers absorb the impact of the knife blade, allowing your knife to stay sharper and your board surfaces to stay smoother. Edge Grain Cutting Boards features full length wood rails approximately 1-3/4″ wide that span the entire length of the board. Edge Grain Cutting Boards features a uniform thickness and true flat cutting surface. To see a video to show the differences, visit our Media Page.

Keep your Boos ® cutting board sanitized by simply washing it with hot soapy water after each use and dry it with a clean paper towel or let it air dry. If you want to sanitize the board more thoroughly, use a diluted mixture of chlorine bleach or vinegar solution that consist of one teaspoon of liquid chlorine bleach in one quart of water or a one to five dilution of vinegar. Do not soak or submerge the board in water, for this will disrupt the moisture content and cause the rails to split. Wood cutting boards are NOT dishwasher safe.

Butcher Blocks

Sprinkle kosher or table salt on your Butcher Block and then use a damp sponge or paper towel to rub the stained or discolored area. The salt will absorb stains, flavors, and odors. For stubborn stains, try sanding down the area with a fine grit sand paper. It is very important to sand with the grain of the wood, never against the grain. This sanding process exposes a brand new wood work surface. Once sanding is complete, it is recommended to oil your Butcher Block with John Boos ® Mystery Oil and/or Boos Block ® Board Cream with Beeswax. This product protects the block and controls its moisture content, keeping it from drying out, cracking or splitting.

Lemon or lime juice with a little salt will go a long way to reducing odor. Sprinkle your Butcher Block with kosher or table salt. Cut a lemon or lime into quarters and use these quarters to rub the salt into the board, squeezing juice onto the board as you go. Let sit for 2-3 minutes and then wipe the cutting board clean with a damp cloth. Use a clean disposable towel to remove excess water or let the butcher block air dry.

We always recommend using both Mystery Oil and Board Cream but the Mystery Oil is always recommended to be used first. The Mystery Oil penetrates deeply through the wood fibers and while the Board Cream is a denser, thicker formula that protects the top layer of the wood surface. Using both care and mainteance products will prolong the life of your Boos Block cutting board.

• Boos Block® Board Cream contains all natural, unbleached beeswax and food-grade oil formula. Board Cream is denser, thicker which gives a protective top layer to the wood surface against foods and liquids. It helps keep the water out and the oil in.

It is extremely important to give your Butcher Block a good oiling on all surfaces every 3-4 weeks depending on your usage. For oil-finished Butcher Blocks, we recommend keeping them oiled with John Boos Mystery Oil and Boos Block ® Cream with Beeswax. When the Butcher Block becomes dry and lighter in color, you know that the time has come to re-oil your block. NOTE: Use only John Boos ® Mystery Oil or Boos Block ® Cream when oiling your Butcher Block. A quick alternative would be to use mineral oil only. DO NOT USE ANY TYPE OF COOKING OIL ON YOUR BUTCHER BLOCKS. THIS WILL CAUSE DAMAGE TO YOUR BLOCKS. With a minimum amount of care and maintenance, you can lengthen the life of your Butcher Block.

Keep your Butcher Block sanitized by simply wiping the surface with a clean hot and wet soapy towel after each use and dry it with a clean paper towel or let it air dry. If you want to sanitize the block more thoroughly, use a diluted mixture of chlorine bleach or vinegar solution that consist of one teaspoon of liquid chlorine bleach in one quart of water or a one to five dilution of vinegar. Do not soak or submerge the board in water, for this will disrupt the moisture content and cause the rails to split.

Varnique Finish is a smooth semi-gloss finish, this type of finish is used for aesthetic purposes or for general food preparation tasks, including rolling dough, but you do not wish to cut upon it directly for it will damage the varnique finish. This finish requires low maintenance and can be easily cleaned with mild soap and warm water and will not need refinished or re-oiled. Varnique is also more resistant to water spotting and staining. If varnique surface is cut, it will need to be resealed using our Boos ® EZ-DO finish. Natural Penetrating Oil Finish is a type of finish used as a cutting surface and is food-safe. The natural oil finish seals and protects the surface of the wood and unlike the varnique finish, can be cut directly upon the surface. It is recommended to re-oil the wood surface every 3-4 weeks depending on your usage. This maintenance keeps the butcher block from drying out and helps preserve the block and extend its life over time. Natural oil finishes can easily be sanded and re-oiled for a like-new appearance.

Minor splits may occur at the ends of your kitchen countertop, if it was cut for installation and the end not properly resealed. If you notice this condition, the cracks should be immediately filled with a matching color wood filler, sanded smooth, and refinished with Boos ® Mystery Oil or Cream.

Warpage of a kitchen countertop occasionally occurs, if one surface expands at a greater rate than the other side. Since the moisture content of the wood used in producing butcher block countertops is tightly controlled, a warped top can be easily corrected. Placing the block onto your cabinet base, it can be drawn down to a flat condition by using 3 or 4 bolts across the width. On an oiled butcher block top the warped condition can also be corrected by covering the convex side with mystery oil and plastic, and then rubbing oil into the concave side of the board repeatedly. This evens out the moisture content of the counter top, and will bring it back to its flat condition.

The wood in a John Boos butcher block top has been kiln dried to a 6% moisture content. During times of high humidity it tends to absorb moisture, which will cause it to expand in width. During low humidity (winter months) it will contract back to its original dimension. When installing a butcher block, allowances need to be made for the seasonal changes. Some cabinet manufacturers slot the top mounting bolt holes. If your cabinets have this feature, be sure the mounting bolts are centered in the slot to allow for both expansion and contraction. If the wood or metal mounting brackets are not slotted, allowance can be made by drilling the hole through the counter approximately 3/8” oversize, and using a washer under the head of the bolts. Attach countertop to counter base using 1/4” lag bolts. The length will vary on the application, but a good rule of thumb is to use a bolt long enough to penetrate one half the top’s thickness. Use one bolt per foot to attach the top widthwise. Use a minimum of four bolts on both ends. Use one bolt per every two feet to attach the length on both sides.

Cutting a butcher block top exposes unprotected hardwood. This needs to be refinished immediately. Failure to do so could lead to cracking of the top. Once you have made a cutout in the top, you should coat the exposed area with EZ-DO poly gel or a silicone acrylic clear caulk. EZ-DO gel is available from your John Boos dealer, the caulk is available at most hardware stores. The EZ-DO poly gel or caulk should be spread evenly with a putty knife the full thickness of the cut portion. EZ-DO poly gel or caulk should also be spread one inch wide around the face side of the cutout perimeter. The bottom side of the top should have a three inch wide spread of caulk around the cutout perimeter. Allow EZ-DO poly gel or caulk to dry. Run a bead of caulk around perimeter of cutout where sink ring will rest. Once sink and ring are in place, wipe off excess caulk squeeze out from ring with a damp cloth. For other concealed cutting alterations apply caulk to unprotected area of cutout only. For areas above dishwashers apply caulk to bottom side of countertop that is overhung from the front of the dishwasher. The caulk should be applied with a putty knife and spread three inches past the unit’s width on either side. All exposed edges that have been altered should be refinished w/oil or EZ-DO poly gel.

We offer two types of finishes for your Kitchen Countertops. Varnique Finish or Natural Penetrating Oil Finish. Varnique Finish is a smooth semi-gloss finish, this type of finish is used for aesthetic purposes or for general food preparation tasks, including rolling dough, but you do not wish to cut upon it directly for it will damage the varnique finish. This finish requires low maintenance and can be easily cleaned with mild soap and warm water and will not need refinished or re-oiled. Varnique is also more resistant to water spotting and staining. If varnique surface is cut, it will need to be resealed using our Boos EZ-DO finish. Natural Penetrating Oil Finish is a type of finish used as a cutting surface and is food-safe. The natural oil finish seals and protects the surface of the wood and unlike the varnique finish, can be cut directly upon the surface. It is recommended to re-oil the wood surface very 3-4 weeks. This maintenance keeps the butcher block from drying out and helps preserve the block and extend its life over time. Natural oil finishes can easily be sanded and re-oiled for a like-new appearance.

Stainless Steel

When referring to the gauge (GA) thickness of stainless steel, the lower the number the thicker the stainless steel. For example, 14GA is a thicker quality stainless steel than 16GA while 16GA is a thicker quality stainless steel than 18GA.

Stainless Steel is durable, and can be long lasting if proper care and maintenance is provided. We recommend using our Boos® Stainless Steel Cleaner to be sprayed on and wiped down with a clean disposable towel. NEVER use an abrasive cleaner or chlorine bleach.
