[Vocabulary] what verb with the glasses?

[dilodi83]

Which verb do you use when you use a cloth to clean the glasses of your sunglasses?
Is it simply "to clean up" or is there a particular collocation or a phrasal verb to express that?
And how to call the cloth used to do this action? Is it a "glasses cloth"?

Thanks so much for your help.

 

[abaka]

Lens-cloth.

I clean my glasses, or I polish them.

 

[SoothingDave]

You clean your lenses. Or clean your glasses.

I call the cloth I use "the bottom of my shirt." ;-)
