Here's kind of a (no, a REALLY) stupid question...
How do I clean the felt on the inside of my lens hood on my 300 f/4 L IS?
I forgot to clean off my finger when I was brushing off a lens hood and I got some residue from a Pringle on it...

This is so embarrassing LOL. This is one of the threads I will look back on in a couple years time and wonder what the hell I was thinking.
