How should I choose a screen cleaning solution?

I saw the thread about cleaning screens with distilled water and a microfiber cloth, but if I want to get a specialized screen cleaning solution, what factors/properties should I look for?


Solution 1:

Don't waste money on solution, diluting vinegar with water works great.

Solution 2:

I often just use plain old Water (H2O). Absolutely no worries about it harming the coating on the screen and it gets the job done perfectly.
