Question: Dishwasher safe?
Document: Don't believe it when they say these are dishwasher safe. Ran them through the dishwasher before I used them and every one of them warped. That being said, I soaked them in hot water to see if they'd go back to being flat (they are very thin, about 1 or 2 mm thick) and they did flatten out. Used them with some very sharp knives that I have and they withstand cutting very well with absolutely NO cut marks.
A slight pain in the rear to clean in the sink (even though the do bend nicely), but they're dishwasher safe, so there's that.I can't complain about these, if I could change anything about them though it would be the material they're made out of. Something a little thicker and rounded along the edges would be superb. But then again I might be the only person in the world clumsy enough to cut my arm on an edge while washing dishes...
These are great! Only complaint is that they curl up a bit, especially after going through the dishwasher.
These mats are fine, they are just not made to wash in the dishwasher, since they tend to curl up.
The colors are bright and the labels are clear. They bend well - easy for transfer. Have not tried them in the dishwasher. Nothing spectacular but does its job.
I couldn't find these locally, so went with this set because of the value. Thin and flexible, they warped a little in the dishwasher but seemed to flatten out in storage. No complaints so far.
Don't put in the dishwasher, they will not keep shape. It should say hand wash only. Does the job though and it helps hubby from using my wooden cutting board with meat.
They're exactly as they are described. However, after a few uses and putting them in the dishwasher, they aren't exactly flat on the edges. Big whoops, whatever. It made my gf happy buying them so she had something to cut on.
These warped in the dishwasher and are so thin I feel like my nice knives will cut right through them. Also, they're super slick so any juice from whatever you're cutting gets EVERYWHERE. Wouldn't buy again.
Perfect for my family of 5. Love being able to fold it up on the sides to funnel things into a pan or similar. Extremely easy storage and great just to drop in a dishwasher rack right after use.
Answer: Yes they are. I've put mine in the dishwasher and had no issues. I usually wash them by hand because they're very easy to clean and I can re-use them sooner. But they can be put in the dishwasher
