Default How to keep Sigma Lens exteriro Clean & Glossy?

I've used several Sigma lenses in the past and currently have a Sgima 150mm f/2.8 Macro. I find that Sigma lenses attaract a lot of dust (on the outside) and tend to look faded quickly, especially the lens hood. My Canon/Tokina/Tamron lenses on the other hand do not seem to catch dust the way Sigma does.

(Just so that there aren't any misunderstandings: all the Sigma lenses I've ever owned, NEVER had any problems with dust collection inside the lens/housing)

Once in a while, I use "Son of a Gun" dashboard polish (non-alcoholic) OR "ArmorAll Tire Form" with a cloth and give Sigma lens a shine, (I've been doing this for the last 3+ years) ... after the polish, Sigma lens stays nice and shiny for couple of weeks but after that its back to dust collection again.

So I would like to know if there are any other (slightly more permanent) solutions which worked for you.

JOOC, since you're in a unique position to answer this, do you suppose that Sigma lenses generate more static electricity than other lenses, and that's what makes them attract more dust than other lenses?

Not sure of static energy but I think it is more to do with the "matte" kinda finish/material Sigma gives on its lenses (especially the lens hood) that causes it to easily collect fine dust.
I've always been happy with what Sigma lens were meant to do, but having non-dust-attracting finish would have been nice ... it just kinda bugs me ... I guess its one of my idiosyncrasies

Am I the only one bugged about dust collection on Sigma lenses ... no solutions from anyone?
