First post here. Hope this the right forum. I wanted to learn about the proceedure used to erase ink on checks. I think they use some kind of solvent or acid or I dont know what they do. Any direction would be appreciated thanks in advance.

White out?

Something more sophisticated than whiteout. Funny though

very difficult,,there awake to those tricks--turn it over,,drip on acetone to loosen,,turn back and lift print with paper towel,,keep dripping and toweling till all gone----then iron it--
