How to clean / polish instruments cluster lens?

Typically you would punctuate the end of a sentence with a question mark if it is in fact a question.

"How to clean / polish instruments cluster lens'"
i could be asking a question, or i could just be advising everyone i'm looking to be ordered around on how to do this, or this could be the venus flytraps of threads where i've lured others into thinking i know a good way to do it, and then don't. either way, sorry for the confusion.

thanks TB & TJ
