No doubt!

If you ever have used SpotShot! Carpet cleaner and stain remover you probably know how incredibly wicked and powerful that stuff is. When it proved safe on the labeling I was surprised.

It wasn't as powerful on grease pencil as I would have thought, so I figured WD-40 would be good on the grease but still not as destructive as SpotShot... Boy was I wrong.

Definitely going to tape over stuff next round.

The unit however is still is great shape and it filled one of the few holes in my Mac collection to date.
