I wash my car regularly once a week or so and one thing i am begining to notice is that my billet grille is shiny on the front but the layers (Top flat part not really showing) are getting dull or tarnished and I don't understand because I dry them off by hand. What do you guys use to keep that grille clean and shinning to full capacity if anything.

Yeah, chrome, stanless steel and other metasl will tarnish over time. Eagle One makes a fiber scrub for wheels and metal cleaning. its called "never dull" - works great!

meguirs makes a metal polish that works pretty damn good.

brasso.

I will have to give those a try I didn't know what would be "safe" to use on it so i just figured wash and dry
