...I've been using a cleaning cloth soaked in dish soap for ages to clean it with a damp cloth. Then simply wipe dry with a soft, lint-free cloth. you don't need any extra cleaning stuff.
Please do not use window cleaner. It can be too aggressive.

I use the Vivanco cleaning solution for flat screens and a microfibre cloth that came with it. With a little patience, it gets really clean. A little tip: clean it when it's cold, then there are no streaks.

I used a dry microfibre cloth for glasses. But it doesn't get completely clean. Cough
