Difficulty: Moderately Challenging
Things You’ll Need:
- Paper towels
- Glass cleaner
- Mild solvent-based cleaner
- WD-40
Step1
If you can start cleaning the whiteboard within a couple of minutes, you have a great chance of cleaning it completely. Give the permanent marker stain a few sprays with the glass cleaner and wipe it immediately with a paper towel. This may smear the marker around a bit, and if you let it set, it may stain that way. Keep spraying and wiping with fresh paper towels to get all of it up when it’s still fresh.
Step2
If it sets in for longer than a couple of minutes, try using a solvent-based cleaner and paper towels instead. This will almost always lighten the stain significantly, if not remove it entirely.
Step3
If you can still see some staining, try rubbing it hard with a little WD-40 and a paper towel. When you’re done, wipe the area clean with a damp paper towel.
Step4
Faint stains may continue to fade away over time with continued use of erasable markers and whiteboard erasers, so don’t necessarily give up on your whiteboard if you can’t get it completely clean.
