How to Rid Mildew and Hard Water Stains From the Shower — The Grandma-Approved Trick That Actually Works

If you have a glass shower door, you know the struggle all too well:
One day it’s crystal clear and elegant — the next, it’s cloudy with hard water spots, streaked with soap scum, and streaked with black mildew along the seams.

No matter how often you wipe it down, the grime comes back — fast.

But what if you could make your shower glass sparkle like the day it was installed — without harsh chemicals or hours of scrubbing?

Enter a simple, genius cleaning hack from a woman dubbed “This Grandma Is Fun” — who discovered that Jet-Dry and dish soap are the ultimate dynamic duo for banishing hard water stains and mildew — safely and effectively.

And the best part?
You probably already have everything in your kitchen.

The Problem: Why Shower Glass Gets So Dirty

Glass shower doors are beautiful — but they’re also magnets for buildup:

• Hard water stains – Caused by calcium and magnesium in water, leaving behind chalky white residue
• Soap scum – A filmy layer from soap and body oils
• Mildew and mold – Thrives in warm, damp environments, especially in silicone seals and corners

Over time, these layers stack up, making glass look permanently dull — but the truth is, it’s not ruined.
It just needs the right treatment.

The Solution: Jet-Dry + Dish Soap — A Powerful, Natural Clean

This cleaning method is so effective because it targets all three problems at once:

• Dish soap cuts through grease and soap scum
• Jet-Dry (a rinse aid used in dishwashers) contains surfactants and citric acid that dissolve mineral deposits and prevent water spots
• Together, they create a low-foam, high-power cleaning solution that leaves glass streak-free and shiny

Step-by-Step: How to Clean Your Shower Glass Like a Pro

What You’ll Need:

• A dish wand (like a Spray-and-Wash wand)
• A non-scratch scrubber (swap the sponge for a soft scrub pad)
• Liquid dish soap (Dawn, Palmolive, etc.)
• Jet-Dry rinse aid (original formula, not gel)
• Water
• A squeegee (for finishing)

Instructions:

1. Prepare the Cleaning Solution

• Remove the original sponge from your dish wand.
• Attach a non-scratch scrubber (to avoid scratching glass or finishes).
• Add to the wand reservoir:
  • 1 teaspoon of liquid dish soap
  • 1 drop of Jet-Dry
  • Fill the rest with warm water

💡 Why so little Jet-Dry? It’s concentrated — a little goes a long way.

2. Mix and Wet

• Tip the wand up and down to gently mix the solution.
• Wet the entire shower glass and surrounding tiles with water.

3. Scrub Away the Grime

• Use the wand to scrub the glass in circular motions, focusing on:
  • Hard water spots
  • Soap scum
  • Mildew-prone areas (tracks, seals, corners)

The solution will start to break down buildup instantly.
No need to let it sit — it works on contact.

4. Rinse and Squeegee

• Rinse the glass thoroughly with clean water.
• Use a squeegee to wipe down the glass from top to bottom.
• Wipe edges with a microfiber cloth to prevent water pooling.

✨ Result: Glass that’s crystal clear, streak-free, and spotless — no vinegar fumes, no elbow grease.

Bonus Tips for Long-Term Shine

✅ Use the squeegee after every shower — this is the #1 way to prevent buildup
✅ Spray a drop of Jet-Dry in your wand weekly for maintenance
✅ Keep a microfiber cloth in the bathroom for quick wipe-downs
✅ Ventilate the bathroom — reduce humidity to slow mildew growth
