Your choice! My Opinion, "Dirt makes a chip look, well Dirty, I hate Dirt" I clean all my chips that need it. I use Armorall "Multi- Purpose Auto Cleaner", take a small soft tootbrush, spray chip and wait 10 to 15 seconds then brush in gentle circular motion...BE CAREFUL when cleaning HS, or leave it along altogether, could take HS off if not careful. Usually HS area not that dirty, so I leave it along. Unfortunately, I Learned that the hard way...
Again, it's your choice.....
