Still no one answered my question lol. Is it safe to clean the lens and LCD screen with alcohol wipe ?
Well, here's the thing. I'm am completely neurotic with my gear and baby everything. Even my lenses from the 80s that I bought new look like new. Same with my music gear. My guitars look pretty much like they just came from the store even though they've been around the world and used quite a bit. I don't get how some people end up with dinged up stuff and others think that makes them more "professional" looking.
Anyway. Some of these precautions are probably unnecessary. The glass and the coatings are very sturdy. I compare it to my eyeglasses that I need to wear every day. Those are high quality (real) glass with coatings similar to what's on our lenses. I wash them under water with dish washing soap. They last for years.
Now, alcohol is a different issue. It's probably safe for the glass but I'd be worried about some of the plastics and rubber materials. They may dry out or react with alcohol. So I'd stay away from that.
