Title: Dirty lens hood.
Post by: couleur on July 05, 2007, 05:49:32 am: I own a Canon EF 17-40mm f/4 USM L. But after a few months of usage, I notice that the inner lens hood is sucking up a lot of dust. And I find it very difficult to clean it.

Do anyone have any idea how to remove the dust stains?

You say stains, and I'm a bit perplexed... on the inside of my lens hood there's a lot of "lint", which comes out quite well if I remove the hood and use a lint brush.

Because it's felt, I'd look to using a clothing brush (different from a lint brush) and see if the stains go away. Not sure what would stain it though...

Its something sticky, and I have no idea where I got that.

In addition to brushes/soap/water you may want to try fabric wipes like Armor All Wipes (or equivalent). But in any case, don't spend more than a new lens hood.
