Today I used the bottom of my T-shirt to gently wipe some stubborn dust of the front element of my lens (i.e. I took the filter off and cleaned the lens itself). Quite by chance I've stumbled upon a post on a web page this evening saying that you should never use anything but an approved lens cloth to clean the front element as alternatives can erode the coating (???). This appears to be a post from a non-pro and I'm suspicious about the reliability of such info; but another part of me is suddenly worried as, although I don't make a habit of it, I have done this before.
Is it nonsense do you think? I would be inclined to say yes but I'm really not sure. My lens is the Canon EF70-200 F4 L by the way.

I really doubt that a T-Shirt (as long as it is clean and the cloth is soft) can do any damage to the coating of a lens. As far as I know the coat is sprayed on the lens and burned in so that you can't really damage the coating itself without scratching the whole glass.

Jeff said it well. Don't make a habit of it. It will scratch your lens in the end, if you continue to do it. I use Kodak lens cleaning tissues. Think thin tissue paper and you're not even close! This paper is so fine and soft it's unreal. Take a couple of those babies and fold them over, mist the lens up with yor breath a little and wipe. Smeer free and perfect results every time. I strongly recommend them.
