Shower Glass Care Guide

Caring for your shower glass is very simple. Once it has been protected, the glass becomes even easier to clean and maintain.

  • You just need to understand a few basic principles and follow a simple process.

  • You don’t need any special skills, and you don’t need to overthink it.

  • If you follow the process shown on this page, your glass will stay clear, easy to clean.

Understanding what causes hard mineral staining on your shower glass

Even though your glass has been protected, the water source at your home remains the same.

When you turn on your shower, mineral-laden water comes into contact with the glass. As that water evaporates, the minerals are left behind on the surface.

Unfortunately no coating can change the water coming out of your tap.

The purpose of NanoGlass Protection™ is to protect the glass from the long-term effects of this mineral buildup. It creates a easy-to-clean non-stick surface that repels water, meaning there is significantly less water left on the glass, and what remains is much easier to remove.

Cleaning and Maintenance

To maintain the performance of NanoGlass Protection™, the glass must be cleaned once per week.

The most effective way to maintain the glass is to dry it after each use. When this is done consistently, the weekly clean becomes even easier. In many cases, this may be as simple as a quick wipe with a damp microfiber cloth, followed by drying the glass.

If the glass is not dried regularly, or visible buildup is present, a more thorough clean will be required, but its still super quick and easy.

How to Clean Your Shower Glass

Please watch the videos below for a full demonstration of the cleaning process. There is one video for enclosed showers, and also a video for shower screens.

The steps that follow form part of the care instructions and should be followed to ensure the glass is maintained correctly.

Step 1 – Apply Cleaning Solution and Agitate

  1. Start by preparing a small container of clean water. This can be a bucket or container. Around 10–15 cm of water is sufficient. Warm water is recommended.

  2. Apply a small amount of dishwashing liquid directly onto a shower loofah (approximately a $2 coin-sized amount)

  3. Dunk the loofah into the water and begin working it across the glass surface. As NanoGlass Protection™ repels water, you will need to regularly re-dip the loofah into the water to maintain a good level of moisture and lather on the glass.

  4. Continue working across the entire surface, ensuring all areas are evenly covered.

  5. Focus on evenly covering the glass and agitating any buildup, including soap residue and light mineral spotting.

Key Points:

  • Use a container with a small amount of water — it does not need to be full

  • Warm water helps improve cleaning effectiveness

  • Apply dishwashing liquid (any brand) directly to the loofah (not into the water)

  • Regularly re-dip the loofah to maintain moisture on the glass

  • Ensure full coverage across the entire surface

Step 2 – Remove Soap from Edges

Before rinsing the soap off the glass, use a microfiber cloth to clear approximately 100 mm around top edges, gaps, and openings.

This helps prevent water and soap from running onto untreated areas during rinsing. The point of this is to create less work, but if some water escapes onto the dry side of the glass it can just be wiped off later.

Key Points:

  • Wipe edges before rinsing

  • Focus on gaps, hinges, and panel joins

  • Reduces water transfer to other areas

Step 3 – Rinse the Glass

Rinse the glass thoroughly using warm water to remove all remaining detergent. Take the detachable showerhead and use it to direct water across the surface and control where the water flows.

Pay particular attention to areas around openings, edges, and gaps between panels. Direct the water away from these areas to minimize it spilling onto the opposite side of the glass. If some water does escape, this is not an issue — it will simply need to be dried afterwards.

Step 3 Alternative Method (If You Don’t Have a Detachable Showerhead)

If your shower does not have a detachable showerhead, you can still rinse the glass effectively. Use a microfiber cloth to remove the majority of the detergent from the surface first.

Then, using a container of clean water (such as a bottle or small bucket), pour water across the glass to rinse off the remaining residue.

Work methodically from top to bottom, ensuring all detergent is removed before moving to the drying step.

Key Points:

  • Use warm water to rinse off all detergent

  • A detachable showerhead allows better control of water flow

  • Be mindful of gaps and openings between panels

  • Direct water away from areas where it can spill through

  • Any escaped water can be dried afterwards

H3: Step 4 – Dry the Glass

Using the supplied glass drying towel, remove all remaining water from the surface.

Work methodically from top to bottom, rotating the towel to a dry section as needed.

Key Points:

  • Remove all visible water

  • Rotate the towel regularly

  • This step prevents spotting from forming

Step 5 – Final Inspection

Check the glass for any remaining marks or residue.

If required, lightly rework any areas and dry again to achieve a clear finish.

Targeted Removal of Stubborn Buildup

In some cases, areas of soap residue or light mineral spotting may remain after the initial clean.

This is more common in lower sections of the glass (typically from knee height down), where soap buildup can form and give the glass a slightly white or frosted appearance.

If this occurs, repeat the cleaning process in the affected areas only.

Instead of using the shower loofah, switch to the supplied ice blue glass-safe abrasive pad.

Work over the affected area using the same method as before — applying detergent, agitating the surface, rinsing, and drying — but only where required.

  • The ice blue pad is only required where soap scum or stubborn buildup remains

  • It is typically used in lower sections of the glass where soap residue accumulates

  • It may also be required if cleaning has been missed and staining has begun to develop

  • This is a targeted escalation step — not part of the regular cleaning process

Important:

Before using the abrasive pad, inspect it to ensure it is clean and free from any debris. Although the pad is safe for use on glass, any trapped particles (such as grit or dirt) may cause scratching if present.

Removal of Heavy Mineral Staining (Advanced Method)

In cases where cleaning has been missed for an extended period, mineral staining may become more firmly attached to the surface and may not be removed using the standard cleaning process or abrasive pad alone.

In these situations, a mild acidic solution can be used to help break down the deposits.

  1. Prepare a solution of approximately 80% white vinegar and 20% water in a spray bottle.

  2. Apply a disposable paper towel (such as a kitchen “handy towel”) directly onto the affected area of the glass, then spray the solution into the towel until it becomes saturated and adheres to the surface.

  3. This allows the solution to remain in contact with the staining, giving it time to break down the deposits.

  4. Leave for 10 minutes, then remove the paper towel, spray the area again and work the ice blue glass-safe abrasive pad over the area.

Important:

  • The coating will repel liquids, so applying the solution directly to the glass without a towel will be ineffective

  • The towel allows the solution to stay in contact with the surface

  • Only use this method on affected areas, not the entire panel

Key Points:

  • Use only when standard cleaning and the abrasive pad are not sufficient

  • Apply the solution using a saturated towel to maintain contact

  • Follow up with the normal cleaning and drying process

  • Do not allow heavy buildup to remain for extended periods

If Staining Persists

If staining cannot be removed using this method, further treatment may be required.
