costa del mar sunglasses, how do u clean the lenses?

Microfiber towel

Under armour cotton t-shirt (usually wearning one most days) works well for mine

I just bought me a big microfiber towel off of the internet. My Costas came with a small one but I wanted a bigger one.

Only use purified water, preferably tears from a virgin.
For wiping, use 1000 count, hand spun Egyptian cotton, light colors only.
For drying, use a ultrasonic blower, between 1300-1350 CFMs, no more, no less.

Then, encapsulate the glasses in a clean Ziplock inside the provided hard case.


Don't let this happen again.

If I have oil from my forehead/eyelashes on the inside, I find licking them then wiping with microfiber clothe or t-shirt cleans them well.
