Cara membuat Pembersih Lensa


LIQUID EYEGLASS CLEANER AND “ANTI-FOG”

This product is a small plastic vial with screw cap, in which a piece of chemically saturated folded felt is packed. When the screw cap is removed, this wet piece of felt extends up and above the top opening of the vial, so that the plastic container serves as an applicator when the screw cap is removed.

The product is designed as a quick and easy lens cleaner for eye glasses and to use it, you simply remove the cap, dab the wet felt lightly on each side of the eye glass lens and then polish off with a handkerchief or tissue. It not only cleans the lens with a sparkling clarity but it also retards fogging of the lens under certain conditions of heat and cold.

Another feature is its long lasting effect, so convincingly demonstrated by suggesting that the customer or prospect smear a LENZ-BRITE cleaned lens with his finger and then polish off with his handkerchief, without further application of the cleaner. This feature makes one application last all day long.

The product is simple to make – all that is needed is your vial which may be plastic or glass, the felt or any absorbent substance that will hold the non-drying cleaning solution and the solution itself. The absorbent substance may be felt, synthetic sponge, cotton wicking, or even a piece of cloth rolled up to fit the small container or dispenser.
