Cleaning & Preparation: Why It Matters Before Waterproofing

Zakia Ashraf

When it comes to battling the great British weather, cyclists and motorcyclists know the struggle all too well. Rain, road spray and fog can quickly ruin visibility and comfort. That’s why products like anti-rain sprays and hydrophobic coatings are such a game-changer. But here’s the secret that many riders overlook: preparation is everything.

Applying a waterproofing treatment to a dirty or greasy surface won’t give you the results you’re after. In fact, it can shorten the lifespan of the product and reduce its effectiveness. Think of it like chain maintenance, you wouldn’t lubricate over dirt and grit, so why waterproof over grime?


Why Cleaning Comes First

  • Better Adhesion - Waterproofing sprays create a thin, protective layer that bonds with the surface. If there’s a film of dust, mud, or road grease in the way, the spray simply won’t stick properly. Clean glass or visor = maximum bonding.
  • Improved Longevity - A well-prepared surface means your waterproofing treatment lasts longer. Instead of reapplying every few rides, you’ll enjoy weeks of clearer visibility with less maintenance.
  • Crystal-Clear Results - Dirt left behind can cause streaks and patchiness once the product dries. Proper cleaning ensures an even finish, no smears, no distractions, just clean vision on the road.

How to Prepare Your Surfaces

Whether you’re treating your helmet visor, bike lights, or motorcycle windscreen, a little preparation goes a long way:

  • Step 1: Rinse Away the Obvious Dirt
    Use clean water to remove mud, bugs and grit. Avoid scrubbing with rough cloths that could scratch.
  • Step 2: Use a Dedicated Cleaner
    Everyday glass cleaners often leave residues that actually repel waterproof coatings. A product like VisioCrystal is formulated to clean deeply while preparing the surface for treatments.
  • Step 3: Dry Thoroughly
    Use a microfibre cloth to avoid streaks. Ensure the surface is completely dry before applying any anti-rain spray.
  • Step 4: Apply Your Waterproofing Spray
    Now that the surface is spotless, apply your VisioDry treatment evenly, following the instructions. Buff lightly for a clear, hydrophobic finish.

The Pay-Off for Riders

For cyclists, this means riding with confidence even when the rain sets in, no more craning your neck just to see through water-streaked lenses. For motorcyclists, it means clearer vision at higher speeds, improved safety in poor weather, and less reliance on constant visor wiping.

By taking a few extra minutes to prepare properly, you’ll not only get the most out of your waterproofing products, but you’ll also enjoy smoother, safer journeys.

Waterproofing sprays are powerful tools, but only when used correctly. Cleaning and preparation are the unsung heroes of effective waterproofing, giving you longer-lasting protection and sharper visibility where it matters most.

At VisioDry, we design products that work hand-in-hand: VisioCrystal for preparation, and our anti-rain sprays for lasting protection. Together, they keep you riding with confidence, no matter what the weather throws at you.

Frequently Asked Questions

Why should I clean my visor or windscreen before using an anti-rain spray?

Because dirt, grease and dust stop the waterproofing layer from bonding properly. A clean surface ensures maximum effectiveness and durability.

Can I use a regular household glass cleaner before applying waterproofing?

It’s not recommended, many household cleaners leave residues that interfere with hydrophobic sprays. A specialist cleaner like VisioCrystal is ideal.

How often should I clean and reapply waterproofing?

This depends on weather conditions and mileage, but most riders benefit from reapplication every few weeks or when water stops beading on the surface.

Do I need to dry the surface completely before spraying?

Yes. Applying to a damp surface can cause streaks or uneven coverage. Always dry thoroughly with a soft microfibre cloth.

What surfaces can I prepare and waterproof?

You can treat helmet visors, goggles, bike lights, mirrors and windscreens – basically any clear surface where visibility matters in wet conditions.
