Marking boards in the kitchen
Mark Brettchen in the kitchen for special use with nail polish: I have in the kitchen like the cheap boards from Ikea. They are white. One for meat and one for bread and vegetables. I used to mark them with an edding earlier so I would not confuse them. Unfortunately, when rinsing but gradually disappeared again.
That's when I came up with the idea of simply marking the boards in the upper corners, which you do not need anyway, with nail polish. Frequent rinsing can not harm this and mistakes are excluded.
