Topic tags/keywords: sanitizing cutting boards

I just had a question asked of me about sanitizing one of my end grain cutting boards in a microwave.
I always have thought that would damage them or at least degrade the glue (titebond III).
She tells me she just watched a video that recommends this, of course she cannot send me a link!
Any thoughts on this? I have a life time warranty on the glue joints so I sure don’t want to endanger my work!!!!

Sanitize it with a bleach and water solution. 20 parts water to 1 part bleach should be good. Mix it up, scrub the board with it, wash it as normal, and dry it off.

No idea,
But I would tell her you do not recommend it and that would void the warranty.

Remind her that if she breaks it, she fixes it.

If she microwaves it long enough it will damage it.
Will the wood char before the glue fails? I don’t know.
Try a piece of cutting board scrap in the microwave to see what happens.

I can’t see why it would damage it if you only do it for 30s or a minute. If you’re doing it for 5 minutes though, all bets are off.

I don’t think heat alone would be enough to loosen the glue bond, you would also need moisture. Maybe an email in to the glue company?

I baked mine in an oven for a while to let the oil absorb better, but it broke one of the glue joints at the edge due to warping (titebond III). So beware the heat approach.

I’m not sure why you would want to do something like this at all—the only cleaning an end grain board should need is to scrub it off with some mild soap water, rinse, and dry.

DEFINITE NO on microwave

Article in NY Times

http://www.nytimes.com/1996/10/02/garden/of-cutting-boards-and-cleanliness.html

Robert F. Schiffmann, the president of a microwave consulting company in Manhattan, wrote to The Times in August that ’’heating wood for five minutes on full power is especially dangerous and will certainly lead to some fires’’ because materials like wood exhibit ’’runaway heating or thermal runaway,’’ meaning the hotter they get when microwaved, the faster they heat.

Further, Mr. Schiffmann said, the heating is more concentrated inside the wood, so a board can burst into flames after it has been removed from the oven. A buildup of steam can even cause the board to explode. He said that over many years his company, R. F. Schiffmann Associates, which tests products for the microwave industry, had experimented with wood in microwaves.

Is that the last and final word, probably not… but if somebody was ASKING if it was a good idea, I would just say NO, and go the bleach route.

Even bleach is not necessary, the bacteria can’t multiply on the wood surface and quickly die when pulled into the wood. When washing only with a sponge, hot water and detergent, wood is safer than plastic.

Of course, a bit of disinfecting won’t hurt, but personally I try to avoid using bleach as much as I can.

There is a lot of talk on sanitizing boards in my arena, and for my personal use the majority of my work is done on wood that gets cleaned with soap & water and allowed to dry, and then for meats etc, I use poly boards that can go through the dishwasher and allowed to air dry, bacteria has to have moisture to propegate.

This is a fairly accurate article on the properties of wooden boards and how it is not necessary to sanitize them with chemicals.

For years I was in the bleach solution camp, it was what was trained and promoted by the health departments, but then it was later shown that a bleach solution loses it's effectiveness after 24 hours of dilution so there was no point to make a bottle of bleach solution to sanitize the board.

So it’s soap & water and a raw meat specific board for my kitchen at home, and different color poly boards for my work kitchens for simply financial reasons. Most important thing with the both of them is to let them air dry completely before storing.

Microwave??? Nah, never had a board that small or a micro THAT BIG.

My only intention is to provide her with an answer to her question! I don’t plan on doing this myself! LOL!!! I am going to tell her I don’t believe that to be necessary and that it will void my warranty to her! Thanks for all the feedback! It was all helpful!!!!

Heat is one way to take apart wood joints.
