Question: dishwasher safe?
Document: Overall, I&#8217;m really liking these boards. I think I&#8217;ll get over the fact that they are heavy and not dishwasher safe, and focus on the anti-bacterial qualities and the sturdy construction.
Personally I loved these boards. You take them out of the package and they have a very smooth feel to them. Some cutting boards are not dishwasher safe, but these are able to be used in the dishwasher which is a big deal to me. I am always about finding ways to save time.
Not dishwasher safe as described. About 2 weeks after purchase the light colored ends of the small board fell off. It's a good thing bamboo is sustainable, because I'm treating these as short term disposable cutting boards.
Very good quality board. Make sure to rub some coconut oil on it every now and then. They are not dishwasher safe but that's ok since I generally scrub my cutting boards in the sink since I only run the dishwasher every few days.
It&#8217;s good to note that these cutting boards are not dishwasher safe. Which is not a problem for me since I don&#8217;t have a dishwasher.I love that the boards are eco-friendly, made with 100% renewable resources. I threw away all of my old bamboo cutting boards after trying these.
the product arrives exactly as it says...and it is great to use! we have accidentally put it in the dishwasher and it has been fine.
Very nice clean cutting boards that are environmentally friendly. Been using them for three months and they've been great! We wash them by hand so don't know about dishwasher durability, also we use coconut oil to keep them in good shape.
These are light weight and so attractive two people have asked where I got them. I am washing them in the dishwasher with the understanding that this will probably shorten their usefulness; however, they are so affordable that I choose the high temp cleaning over long life. Oiling is good for them and makes them prettier.
These bamboo cutting boards are thick and tough. Clearly, these are made from fine, strong bamboo, and not merely filled with particle board. I&#8217;ve only owned thin plastic cutting boards in the past, so at first, these felt very bulky and heavy (even though bamboo is 33% lighter than Oak), but I&#8217;m beginning to see how a sturdy and durable board makes food prep a little more safe and practical.
works way better then any other type of board i've had ie plastic, glass. and if you take care of them with cleaning and oil after use when you first get them they will pay for themselves.
Answer: We occasionally wash ours in the dishwasher  but never use the drying cycle. Heat cycles will accelerate aging and cracking in wood products.
