I was shooting in front of a fountain and then the wind has changed its direction. Now the front element of my 14-54 have got some water marks, which I cannot clean off with a pen like this.

I would like to learn some tips on lens cleaning. I checked youtube and they seem to use some chemical product with a special paper. But there's no detailed specifications.

Best Regards,
Tony

I am using a soft piece of tissue moistened with a lens cleaning solution which is isopropyl alcohol. You can also use ethyl or methyl alcohol (ethanol or methanol).

Breath on the element and wipe in circular motions with a microfibre cloth.
