The kids have ended up spraying the board with glass cleaner & use paper towels to clean it.

I've even tried using in conjunction with the spray (made by the same company), just smudges my white board, doesn't actually erase anything

I'm expecting it to get worn down fairly fast with consistent use.

The new cleaner Erase Board Eraser works well after it is used for a week or so.

I would recommend using this along with the Expo Disposable Wipes for a once a week clean up of your dry board.

Works REALLY well when using EXPO markers but not so good on other markers

When using other marker's does not erase clean, use have to use a wet towel or wipe to get it clean, which defeats the purpose of having an eraser.

Great use.
