Leader is a modern cleaning agent developed for spectacles, camera lenses and other optical items made of plastic or glass. Leader was developed for cleaning all types of spectacle lenses. Instructions for use: Press the spray pump and apply to the desired surface. Clean the lens with a dry, soft cloth. If the lens is very dirty, we recommend rinsing it under running water first to remove any dust particles that could potentially scratch the lens. Do not spray near the eyes. Do not inhale. Do not use with contact lenses. Keep away from children. Alcohol-free. Contains Ethylenglycolmonobutylether.
