How to Restore Grill Insert from Water Stains?

[Ballzo]

Can anyone recommend something to restore the finish on the stock grill inserts. They look grey and water stained after so many washing without blowing it dry.

you can always try Adam's In and Out Spray or VRT to bring it back, depending on how bad it is it may permanently be stained. All you can do is make it look better temporarily.

Anyone else have any suggestions?

Is this for the A6?

Yep. If you're a fan of Adam's products, try some of their Metal Polish #1. It also works wonders on plastic lenses that have water etchings or haze/fog from U/V damage.

I think this plastic might be to porous for a polish? Its the black parts that have stained so bad. The chrome still looks good.
