Yes, and it's the step most people skip. Grease, fingerprints and road film prevent water-repellent treatments from bonding to the surface properly. Even a small amount of residue can cause uneven coverage and reduce how long the treatment lasts. Spraying VisioDry anti-rain directly onto a dirty visor is the most common reason it underperforms. Clean first with VisioCrystal, let it dry, then apply your anti-rain treatment for best results.

VisioCrystal is safe for use on all polycarbonate and plastic visor materials, prescription glasses, cycling glasses, ski goggles, swimming goggles, camera lenses and most screen surfaces. It's streak-free and leaves no residue. If you're unsure about a specific material, apply a small amount to a discreet area first.

Spray a small amount onto the surface or onto a clean microfibre cloth. Wipe gently in circular motions to lift grease, road film and residue. Allow the surface to dry completely before applying any water-repellent treatment. Do not use on hot surfaces or in direct sunlight. For best results when applying VisioDry anti-rain spray afterwards, ensure the surface is fully dry and at room temperature.

Yes. VisioCrystal is a standalone surface cleaner and works as a prep step before any water-repellent or hydrophobic treatment, not just VisioDry. If you've been getting poor results from any anti-rain product, the surface prep is almost always the issue and VisioCrystal will help. However, we do recommend to use the Visiodry anti-rain repellent as they were made for each other.
