Query: Color comes off

The designs on these place mats are adorable, but the color comes off very easily. We got a truck one and I thought the ink came off because I was using vinegar to clean it sometimes. I tried getting another one and I've used a very mild soap. The same thing is happening. It looks awful and I can't imagine it's great for kids to eat the ink. I am very disappointed with this product.
