Ideal product for masks with glass lenses previously treated with Absolute Cleaner, and for swimming goggles and masks with polycarbonate lenses.
The C4 and Real Chimica partnership
Born from the collaboration between C4 Srl, a company specialised in the production of scuba and freediving equipment, and Real Chimica Srl, a world-leading manufacturer of cleaning products (including the well-known Chanteclair), this product was developed to clean and permanently remove silicone oils from the glass lenses of any mask, new or used, without any drawbacks. A further goal was to create a dedicated anti-fog treatment for masks with lenses already treated with Absolute Cleaner, as well as for masks and swimming goggles with polycarbonate lenses, to prevent fogging caused by factors other than silicone oils, such as the use of sun cream or temperature differences between body and water (more frequent in pools than in the sea). After a year of collaboration and hundreds of tests, the two products Absolute Cleaner and Extreme AntiFog were born.
How to use
Spray the product onto the inside of the lenses before wetting them (recommended amount 3-4 ml) and leave to act for 2 minutes. Then rinse the mask or goggles. It is recommended to use the product immediately before use.
