If you've ever left dry erase ink on the board for a few days, you know it can sometimes be difficult to remove. Cleaning weblog How to Clean Things shares several methods for removing old dry erase ink, but being a parent my favourite is using baby wipes.

It may take a bit of scrubbing, but the moist wipe will remove the ink easily enough and is more convenient for me than pulling out vinegar or bicarb soda. Keep in mind that you can also use baby wipes to erase deodorant marks from dark clothes. If you don't have baby wipes on hand, check out the source link below for several other methods.
