'The Lens Pen is the only thing to use on your lenses H.
I Wouldn't and Don't use anything else.
Make sure you get the original Lens Pen, there are a lot of cheap imitations out there especially on the net.
I had a link to how to spot a fake, I'll try and find it for you.
I get mine from the Geographic Shops, that way I can check to make sure they are the original ones.
