Windscreen had spots baked on from months of parking under a sprinkler. Nothing shifted them until I tried Prizm - glass is clear now and I followed up with a hydrophobic sealant straight after.

Chemical Restoration
Lift what washing leaves behind
Prizm goes after the water spots and acid rain stains that have chemically bonded to glass rather than sitting on the surface. Where glass cleaners and clays reach their limit, Prizm's chemical action lifts the deposit without touching the glass itself.
Why Prizm
Restoration without compromise
Chemical precision where mechanical methods fall short.
-
Chemical, Not Mechanical
Lifts bonded mineral deposits by chemistry, so the glass surface is never abraded or scratched in the process.
-
Tackles Acid Rain Etching
Removes acid rain staining that survives washing and glass cleaners because it has bonded to the surface, not settled on it.
-
Pairs With Glass Protection
Leaves glass in the ideal state for a sealant or hydrophobic coating to bond cleanly after treatment.
-
Clear Surface Compatibility
Designed exclusively for automotive glass, with an unambiguous warning to keep it away from mirrors and silver-backed surfaces.
Prizm vs. the Alternative
Chemical removal vs. generic glass cleaners
Standard glass cleaners handle loose surface grime well. Prizm exists for the situations they cannot resolve - where deposits have bonded to the glass and only a targeted chemical approach will shift them.

Professional Grade
A tool for the right moment, not every wash
Prizm is not a product you rotate into your weekly routine - it is the one you reach for when the glass is genuinely compromised. Treat the surface, restore clarity, then follow up with a sealant on clean, contaminant-free glass.
Reviews
What our customers say
Solid product for what it is. Heavy mineral etching needed two rounds, but it came off without any polishing. Good to have in the kit for those stubborn cases.
Client's bakkie had acid rain marks that three different glass cleaners ignored. Prizm lifted them cleanly. Read the instructions carefully about mirrors - that warning is serious.
Not an everyday product, but it does exactly what it says when you need it. Arrived well packaged. The no-mirrors rule is worth highlighting to anyone who hasn't read the label.
Questions
Frequently asked
How do I apply Prizm to the glass?
Apply a small amount of Prizm directly to the affected area of glass. Work it in gently with a microfibre applicator or cloth, allow it to dwell briefly so the chemistry can lift the deposit, then wipe off and inspect. Repeat on stubborn spots if needed. Always work on a cool, shaded surface.
Can I use Prizm on painted surfaces, wheels or trim?
No. Prizm is formulated for automotive glass only. Keep it away from painted panels, wheels, rubber trims and any other surface. The formula is designed specifically to interact with the mineral chemistry bonded to glass.
Can Prizm be used on mirrors?
Absolutely not. Vonixx explicitly labels Prizm as unsafe for mirrors. It reacts with the silver backing behind the glass and the damage is permanent and irreversible. Mask off or work well clear of any mirror surfaces when using this product.
Will Prizm scratch or haze my windscreen?
No. Prizm works chemically rather than by cutting or abrading. It lifts the bonded deposit rather than grinding it away, so it does not introduce the micro-scratches that mechanical methods can leave behind on glass.
How often should I use Prizm?
Prizm is a restoration product, not a maintenance staple. Use it when bonded water spots, mineral marks or acid rain staining appear that regular washing and glass cleaners cannot shift. Once the glass is clear, return it to the shelf until the situation calls for it again.
Can I apply a glass sealant or coating after using Prizm?
Yes, and it is good practice. Once Prizm has lifted the bonded deposits and the glass is clean, it is an ideal moment to follow up with a glass sealant or hydrophobic coating. The surface is free of contamination, so the sealant bonds properly and delivers better sheeting performance.
Is Prizm suitable for DIY enthusiasts or is it professional-only?
Vonixx labels Prizm for professional use, primarily because of the strict surface compatibility rules - especially the absolute restriction around mirrors. A serious enthusiast who understands those boundaries and works carefully can use it safely, but it is not a beginner-friendly product where you can afford to rush or cut corners.
What kind of water spots does Prizm actually remove?
Prizm targets Type 2 and Type 3 water spots - mineral deposits and acid rain etching that have chemically bonded to the glass surface. Type 1 spots (loose surface deposits that a decon wash removes) do not require Prizm. If standard washing leaves the marks behind, that is when Prizm earns its place.
