Vinegar and water, half and half, gentle circular motions with a clean cotton t-shirt. Make sure not to use too much liquid as it can drip.

plain white vinegar, if possible. red wine vinegar should be saved for your salad. :) – quack quixote Mar 30 '10 at 11:46

I typically clean any LCD displays I have with a slightly damp microfiber cloth. You'll definitely want to use something soft--I've seen quotes online that say nothing rougher than a t-shirt.

I have used Windex before as well, but I noticed slight discoloration on my monitor for several minutes (after which the effect faded).

most Windex formulas contain ammonia -- which is not good for your screen. – deleted Mar 29 '10 at 1:34


I clean my LCD-screens with a very diluted water/dishwasher-liquid solutions and a soft cloth I got with my glasses.

I have been doing this for over 10 years and never had any problems.

I trust you're referring to the stuff for washing dishes in the sink, not the nasty stuff for automatic dishwashers? – JRobert Mar 29 '10 at 14:53
@JRobert - You are quite correct – Nifle Mar 29 '10 at 16:27
