Really helps for killing streaks. I'll go after any stubborn areas (sneeze attacks or reading something funny while having a mouth full of coffee ) by hand first and then squeegee from one side to the other, 3 overlapping passes in all.
The squeegee method you mentioned works really well against streaks without needing any iso.
I did it by hand, then squeegee method and instead of spreading all the yuck on my monitor when drying and it worked out good.
Yeh i have the same monitor and i clean it with what my eye glasses cleaner that comes as a spray.
I spray it on my monitor while its unplugged and whip it with a micro fiber cloth. wait until it try off and then i am back in business
* I am not saying its the best / safest way to clean an expensive monitor but it works well for me. what else do you guys use?
this is how I clean mine , I wear glasses and the spray made for them is the safest product out there, in my opinion.
I even clean my laptops and big screen tv with the glasses cleaner.
