Most cockpit LCD displays, in particular the latest AFD from Rockwell Collins like the one on the 787 or any Proline fusion avionics ( and it’s probably the case for other make), are NEVER to be cleaned with alcohol wipes. The display has an anti-glare coating on the surface, that requires specialized wipes that doesn’t remove or damage that coating. The second you touch those things with alcohol, let alone something else, you’ve just started the removal process of that coating and it’s a vicious cycle after that. The more you clean, the more reflection you get ....etc etc.
Your outfit should supply those wipes ( you get the choice of wipes kit , or a spray bottle with a lint free cloth) in the cockpit for crew to use....this is the best case scenario. Maintenance typically don’t have them too.
