Shower glass is exposed to water, soap scum, steam, and moisture every single day — and over time, this can lead to stains, streaks, and permanent damage.
If you've ever wondered how to protect shower glass or why it looks cloudy no matter how often you clean it, you're not alone.
The good news? Most damage is preventable.
Here are the six biggest causes of shower glass damage — and how to stop them in their tracks.
1. Hard Water Stains
Why it’s a problem:
Minerals like calcium and magnesium in hard water cling to porous glass and leave behind chalky white stains that are difficult to remove.
How to prevent it:
Dry the glass after each use or apply a hydrophobic coating that repels water and minerals before they can stick.
2. Soap Scum Build-Up
Why it’s a problem:
Soap scum forms when soap mixes with hard water, leaving behind a filmy residue that builds up over time.
How to prevent it:
Use liquid soap instead of bar soap, clean regularly with a soft cloth, and apply a protective coating like EnduroShield to reduce residue.
3. Harsh Cleaning Chemicals
Why it’s a problem:
Many bathroom cleaners contain strong acids or abrasives that can cause permanent damage to glass. On untreated glass, they can lead to etching and cloudiness. On coated or treated surfaces, they can break down the protective layer over time.
How to prevent it:
Avoid using harsh or abrasive products altogether. Instead, opt for a gentle, non-abrasive cleaner that’s safe for both protected and unprotected glass.
4. Salt Spray (for Coastal Homes)
Why it’s a problem:
Salt from sea air can settle on bathroom windows or outdoor shower glass, accelerating corrosion and leaving stubborn marks.
How to prevent it:
Rinse glass regularly and apply a long-lasting protective coating to create a barrier against salt and moisture.
5. Scratches from Cleaning Tools
Why it’s a problem:
Paper towels, abrasive pads, and even cheap squeegees with hard plastic blades can leave fine scratches that trap grime and dull the surface.
How to prevent it:
Use a soft microfiber cloth or a high-quality, glass-safe squeegee. We recommend an EnduroShield-approved squeegee to keep your glass clean and clear without causing damage.
6. Steam and Poor Ventilation
Why it’s a problem:
Without good airflow, steam carries minerals and soap particles that settle on your glass and leave behind a dull film.
How to prevent it:
Use an exhaust fan or open a window when showering. A hydrophobic coating also helps water and grime slide off more easily.

FAQs: Shower Glass Protection
How do I protect my shower glass?
The easiest way to protect your shower glass is by applying a hydrophobic coating like EnduroShield Glass Treatment. It creates a protective barrier that repels water, soap scum, and grime — helping to reduce build-up and make cleaning faster and easier.
What causes stains on shower glass?
Stains on shower glass are commonly caused by hard water minerals, soap scum, salt spray, and the use of harsh chemical cleaners. These can leave behind cloudy marks, build-up and streaks — and over time, this build-up can lead to permanent etching. Applying a protective glass coating helps prevent these contaminants from bonding to the surface.
How often should I clean my shower glass?
For best results, clean your shower glass once a week using a gentle dishwashing liquid, a microfiber cloth, or a glass-safe squeegee. Consistent, gentle cleaning helps preserve the clarity and performance of the protective coating.
Can I use any cleaner on protected glass?
No — abrasive or acidic cleaners can strip the coating and damage the surface. Use only suitable products that are safe for coated glass, and follow our glass care instructions to keep the protection performing at its best.
