Using the wrong writing instruments cleaners and or erasers on laminated paper can result in staining smudging and smearing on your hands as well as your page.
Write on laminated posters.
I have about a bajillion ultra fine point sharpies for um georging but i don t really like the idea of lugging around a special solvent.
Spray it on the permanent marker and let it sit for about a minute.
If i need to erase i use the expo marker cleaner like you buy at wal mart.
This is particularly undesirable if you plan to use the same sheet over and over and want it to look clean and fresh each time.
The sheets are more rigid than typical laminated posters and stuff.
