cleansing lens

[luciano costa]

Is it OK to use Sulphuric Ether to clean my lenses? What is the diference betwe en sulphuric ether and etilic ether?

What condition are your lenses in? Most would opt for a simple blast of air (compressed), a quick flick with a brush, or for stubborn marks a lens cleaning fluid and a microfibre cloth.
