Cleaning and disinfecting cutting boards

I had a wee bit of information on using vinegar to clean cutting boards but decided to do a bit of research to find more information about the use of cutting boards. The following is some really good advice on cleaning and maintaining your cutting boards.

Whichever kind of cutting board you use, all cutting boards should be cleaned and sanitized frequently. Some of the various techniques recommended for cutting boards are as follows (you decide which is best):

Hot water and soap - Scrub board with hot water and soap. Rinse and dry thoroughly. NOTE: NEVER submerge cutting boards in a sink of water! Wood is porous and will soak up water causing the cutting board to crack when it dries.

Vinegar - To disinfect and clean your wood cutting boards or butcher block countertop, wipe them with full-strength white vinegar after each use. The acetic acid in the vinegar is a good disinfectant, effective against such harmful bugs as E. coli, Salmonella, and Staphylococcus. Vinegar is especially good for people with chemical allergies. Keep a spray bottle of undiluted vinegar handy for easy cleaning and sanitizing.

Hydrogen Peroxide - 3% hydrogen peroxide can also be used as a bacteria-killer. To kill the germs on your cutting board, use a paper towel to wipe the board down with vinegar, then use another paper towel to wipe it with hydrogen peroxide.

Bleach - Sanitize both wood and plastic cutting boards with a diluted chlorine bleach or vinegar solution consisting of one teaspoon of liquid chlorine bleach in one quart of water or a one to five dilution of vinegar. Flood the surface with a sanitizing solution and allow it to stand for several minutes, then rinse and air dry or pat dry with paper towels.

All cutting boards, and other food surfaces, should be kept dry when not in use. Resident bacteria survive no more than a few hours without moisture. Keep moisture of any type from standing on the block for long periods of time. Beware of moisture collecting beneath the board if you leave it on the counter. If you can, prop one end up when not using your board.

To eliminate garlic, onion, fish, or other smells from your cutting board,:

Coarse salt or baking soda - Rub the board with course salt or baking soda. Let stand a few minutes and wipe salt or baking soda from board, and then rinse. You may need to re-season after rinsing your cutting board/chopping block.

Lemon - Another very easy technique is to rub fresh lemon juice or rub a cut lemon over the surface of the cutting board to neutralize onion and garlic odors. You may need to re-season after rinsing your cutting board/chopping block.

Vinegar - Keep a spray bottle of undiluted vinegar handy for easy cleaning and sanitizing. You may need to re-season after rinsing your cutting board/chopping block.

Use a good steel scraper or spatula often when using the board. Scraping removes 75% of the moisture that builds up on a wooden cutting board. An occasional sanding will return a wooden board to a smooth luster. But never scrub a wooden board with a steel brush (a steel brush will ruff up the finish and should be avoided).

Wooden boards need oiling or reseasoning once a week to seal the grain against bacteria. An oil finish helps to prevent the wood from cracking or pulling apart at the seams.

Before applying oil to butcher block, warm the oil slightly. Apply oil with a soft cloth, in the direction of the grain, allowing the oil to soak in between each of the four or five coats required for the initial seasoning. After each treatment, wait about four to six hours and wipe off oil that did not soak into the wood (oxidation or hardening of the oil will take approximately 6 hours). Re-oil the butcher block monthly or as often as needed.

Before using a new butcher block, season it to prevent staining and absorption of food odors and bacteria. Proper surface treatment is important to guard against germs and/or mold growth on both new and older boards. The wood surface needs an oil that can be repeatedly applied to fill the wood pores and repel food particles, liquids, and oils. Never use any vegetable or cooking oils to treat or finish a cutting surface, as in time the wood will reek of a rancid spoiled oil odor.

USP-grade mineral oil is a popular choice as it is the cheapest pure food-grade oil you can buy (do not use vegetable or olive oils because they can turn rancid). Mineral oil remains safe throughout its life. There are various oils available for cutting boards and butcher blocks. Some are called "Butcher Block Finishes" or "Mystery Oil." Save some money by visiting the local hardware or drug store and purchasing Mineral Oil. (not mineral spirits - this is paint thinner).

When you see the words "food safe finish" in a description of a wood product, this generally means mineral oil has been used. Simply wipe mineral oil on the surface of your board and watch it soak in. When the wood won't take any more oil, you can wipe off the excess with a clean dry cloth. Don't worry about applying too much oil - more is better.

Beeswax is often added to mineral oil and walnut oil to give a tougher finish. The wax of bees has been used for centuries for waterproofing and sealing materials from baskets to cloth and for preserving foods and other perishable materials, including wood. It will make wood water-resistant (though not water-proof) and will help protect the wood surface from use and wear. It will also give a wood surface a nice smooth feel to the touch and leave a gentle, sweet fragrance. Simply shave about 1/2 teaspoon beeswax into a microwave safe dish with a cupful of mineral oil; microwave on high for about 45 seconds. Apple to the cutting board or butcher block while still warm. Save or dispose of the remainder of the oil.

Beeswax Top Coat - A beeswax top coat is an optional addition to the re-finishing process, but is well worth the time. The beeswax sits on the surface of the wood in contrast to the oil that soaks into the wood. As a result the beeswax fills in pores and gaps that thin oil can't bridge. This helps to keep moisture, bacteria, and other contaminants from getting into the wood surface. To apply the finish, simply wipe it on with a clean cloth. The beeswax is a soft paste that has a similar consistency to that of a shoe polish. Excess finish can be easily buffed off with the cloth. Once the finish has had some time to dry it can be buffed to a shine.

To avoid cross contamination, with a wooden cutting board, it would be a good idea to carve a small "v" into the corner of one side of your cutting board and a small "m" into the other side. Then you can always cut your veggies on one side and your meats on the other side and not worry about any chance of cross contamination.

If you are using a plastic cutting board, then you may want to pick up a few different colors. One for poultry, one for red meats, and another for your veggies. That way you don't have to worry about any possible cross contamination. Although you should still thoroughly clean and disinfect your cutting boards after each and every use.

Yesterday was just a bushel load of fun. Not. I had my "annual" exam by the mid-wife at the clinic. Actually it was only 6 months since my last pap test. However, the test yielded "no cells", whatever that means. Hm. They said that didn't really mean anything but they wanted to do the test early. Ohhh-kaaaay... She also scheduled me to come back again in another 6 months for my next pap. Oh joy, joy...lucky gal that I am, huh?

Hm, that reminds me...isn't it about time for the old mans bootay exam?

LOL Oh I can be a wicked one when I want to. Butt (lol) seriously, it's important for his health. Especially at his age. He has an appointment to discuss his stress test with the doctor on the 1oth, I should probably bring the bootay exam subject up then. Hey! It's purely out of concern for my honey buns! LOL

Have a good day and I'll see ya'll soon!

Excellent tips! You just reminded me to reschedule my yearly exam too - I canceled it last month. Thanks! :-)
