Glass Genius is Wellington’s certified applicator of NanoGlass Protection™ — a professional-grade coating system designed to protect glass from staining, corrosion and long term damage. It can be applied to a wide range of glass surfaces, including shower glass, exterior windows, glass balustrades, pool fencing, automotive glass, marine glass, and more.
An invisible barrier that reduces cleaning time and preserves clarity.

This level of water repellency reduces how long water sits on the glass — helping prevent mineral deposits and long-term staining.
How NanoGlass Protection™ Works (And Why It Matters)
Glass might look perfectly smooth, but under a microscope it’s full of tiny pits and valleys. These imperfections trap dirt, minerals, and moisture — leading to stains and scratches over time.
NanoGlass Protection™ bonds at the microscopic level, filling in those pits and valleys to create a smoother surface. The result is glass that stays clearer for longer and is much easier to keep clean. Scroll to the bottom of the page for frequently asked questions (FAQs)

Frequently Asked Questions (FAQ’s)
-
For most homeowners, yes.
Shower glass is expensive to replace, and once it develops permanent staining or haze, it’s not always fully recoverable. What often starts as light spotting can gradually build into damage that standard cleaning can’t remove.
Nanoglass Protection™ helps reduce how aggressively minerals and contaminants bond to the surface — making the glass easier to maintain and helping preserve it long term.
👉 Think of it as an easy to clean coating, that acts as an insurance policy for your glass.
-
Definitely.
There is no such thing as maintenance-free glass. The same water, heat, and minerals are still present every time the shower is used.
What Nanoglass Protection™ does is make cleaning much easier and more forgiving. Contamination doesn’t bond as strongly, so routine cleaning takes less effort — even if it’s not done perfectly every time.
-
It changes how the glass surface behaves.
Instead of allowing water and minerals to sit and cling to the surface, it reduces how strongly they interact with the glass. This means:
Less water remains on the surface
Minerals are less likely to bond
Build-up is easier to remove
Over time, this helps the glass stay clearer and easier to maintain.
-
No.
Water spots are caused by the mineral content in your water supply — and that doesn’t change. Every time you use your shower, mineral-laden water is coming into contact with the glass.
What Nanoglass Protection™ does is reduce how much water stays on the surface, so there’s far less opportunity for minerals to be left behind.
So while it won’t stop water spots completely, it dramatically reduces build-up and makes cleaning much easier.
-
Both.
For new glass, it acts as a preventative measure — helping keep the surface in good condition from day one.
For existing glass, the surface is first restored, then protected to help prevent the same issues from returning.

-
No — but not all coatings are the same.
There’s a big difference between DIY products, entry-level coatings, and professionally applied systems. Many lower-end options provide short-term results but don’t perform consistently over time.
Nanoglass Protection™ is designed for real-world conditions — where glass is exposed to heat, minerals, and inconsistent maintenance.
-
It doesn’t replace maintenance.
There is no product that allows you to do nothing and still get perfect results. What Nanoglass Protection™ does is make proper care much easier and more forgiving.
Even if maintenance isn’t perfect, the glass is far less likely to suffer permanent damage.
-
This is where protection really shows its value.
On unprotected glass, contamination can bond directly to the surface and cause permanent staining or etching.
On protected glass, contamination is far more likely to sit on the coating — meaning it can be removed more easily, and restoration (if ever needed) is significantly faster and more successful.

-
No — in fact, you’re exactly the type of person this is designed for.
In the real world, when shower glass isn’t maintained consistently, it almost always develops heavy staining and can eventually suffer permanent damage.
Nanoglass Protection™ acts as a safeguard. Even if cleaning is irregular, contamination is far more likely to sit on the coating rather than bonding directly to the glass.
That means:
Easier recovery
Better long-term results
A much lower risk of permanent damage
So rather than being a waste of money, it’s often the best protection against real-world neglect due to busy lifestyles.
