How do I get rid of em and make the grills look much cleaner?

get different ones.

theres no way to just clean them? Where can I buy different ones other than a junk yard?

any type of scrubbing to clean the fabric will stretch it out. The yard is the best place to start looking for parts.

its not fabric, its metal

OMG brain fart...

have you tried any type of cleaning solution? shouldn't take much

well being the impatient person I am lol, I went ahead and used the Armor All spray stuff and it for the most part cleared the spots off and leveled out the color. Now I just have some very small spots that I really dont know what they are. Anyway, no I didnt use any cleaner. I'll prolly try that next time. and I have no idea why I never thought of that

mr.clean magic erasers clean anything!

I would also try a degreaser. I've got some citrus stuff that works nice. Put in a spray bottle with ten parts water to one part degreaser and give it a try. Spray it and let it sit for a few minutes and then clean it up.

lol I'll have to try that at some point.

What citrus stuff is it?
