The answer is no, you can't clean the display with any kind of water. It goes into the zebra strips & kills rows of pixels. The zebra strips are held in by expendable metal tabs. The lion kingdom managed to trade some bad rows for other bad rows. The display would have to be covered in packing tape to try to keep water out. The best long term solution is to get a better display. It's so slow, it's not worth trying to save some bad rows.
