Plastic chrome ext. bright-work milky/tarnished

[YorkshireBloke]

Hi,

Finally got to detail the 3.7, first use of clay bar and haven't had a car worth waxing for years!

Thanks to tips on A8 owner's site the job went really well, reviving a neglected exterior and making a start on the interior.

Now I need a tip for reviving the chrome strips on the D2 or if not possible is replacement the only option?? The boot strip is really milky, I rubbed without abrasive cleaner but without any effect.

Thoughts?
