How to clean meter cover case?

[saru2011_imp]

Hi,

Bought a pre owned 2014, and trying to clean up the meter cover case to make it black and shinny. It has white stains covering quite large area, see attached picture. How would you go clean this up? Or should I replace with a new one (CASE ASSY 37300-MGC-305)?

Thanks in advance.

I have used MOTHERS Back -to-Black polish for similar parts , does not last forever but just repeat it once a while.
Used it to bring back discolored indicators etc

Meguiar's PlastX might be worth a try too.

Big fan of 303: https://www.goldeagle.com/brands/303-products/ Worked so well I buy it by the gallon on Amazon. I treat the vinyl cover on bed cover on the pickup, the bike covers (no garage so the covers take a beating from the Sun) and other plastic bits.

Have used Mothers Back to Black (or was it Black Magic?) with some success. Looks good for a week then, meh.
