Is there a way to make the inside of the tips shiny as the outside? Is this even possible? I'm talking about just the inside part close to the outlet. Just the part that can bee seen. Thanks.

 

Yes you can clean them, but they will very quickly turn black again.

 

Pretty much have to wipe them down every day or so, depending on the amount of driving you do. They do look nice when clean.

 

Yo!
Just use soap and water, and with a plastic brush (tooth brush works also)
Kragen has 3 pcs packed brush for $5 bucks (copper, steel, and plastic). The plastic brush one in the package is the best one I have seen so far..

 

Thanks guys.

 

eagle one makes a good chrome cleaner. 2 squirts of that and a MF towel and they will stay clean for about 2 days.
