Why nothing you've tried worked: the stains are minerals, and every spray you've used ran off the glass before it could dissolve them. This foam stays put. The minerals let go.
120-day money-back guarantee. Foam your worst patch, wait 4 minutes, wipe. If the minerals don't move, every penny back. No questions asked.

Ten years of hard water and nothing touched it. Foamed one corner as a test, came back four minutes later and that corner was completely clear. Did the whole door the same afternoon. My husband asked if we got new glass.

Hard water stains aren't dirt, they're minerals, which is why glass cleaner has never touched them. This is a descaling cling foam: it grips vertical glass instead of running off, dissolves the mineral layer, and wipes away with a cloth. No scrubbing, no pads.

It also leaves a clear protective coating so water slides off instead of drying into new spots. One 120ml bottle covers shower glass, mirrors, faucets, shower heads, tile and stainless. Safe on glass, chrome and ceramic. Not for natural stone or marble.

  • Spray onto the stained glass or fixture
  • First deep clean: let the foam sit 3 to 5 minutes
  • Wipe with a cloth or sponge, no scrubbing
  • Rinse for a streak-free finish that repels new spots
After the first clean, a 30-second weekly wipe keeps it clear. Years of thick buildup may take a second application. Not for use on natural stone or marble.

Yes. Every order is backed by our 90-day money-back guarantee.

Foam your worst patch, wait four minutes, wipe. If the minerals don't move, contact us and we'll refund every penny. No questions asked.

Real Results

Drag to see the 4-minute difference

Same glass. One application. No scrubbing.

Glass shower panel completely clear after one application Same glass shower panel covered in cloudy hard water stains

Spray. Wipe. Done.

Clean it once. Then it's a 30-second habit.

The first application does the restoring. Every one after that is just upkeep, because the glass stops holding onto water.

1

Spray it on

Coat the glass and fixtures. The foam grips the surface instead of running off. On your first deep clean, give it 3–5 minutes to dissolve the buildup.

2

Wipe it off

One pass with a cloth. No scrubbing, no pads, no razor blades.

3

It seals as it cleans

A clear protective coating stays behind, so water slides off instead of drying into new spots. Soap scum and hard water can't grab on.

4

It stays clean

A 30-second wipe once a week keeps the glass showroom clear. Works on chrome and stainless too, faucets, shower heads, even kitchen appliances.

Years-old buildup? Run a second application instead of scrubbing. Not for use on natural stone or marble.

Before & After

Every door tells the same story

Tap through. Same foam, same 4 minutes, zero scrubbing.

Before and after: hazed walk-in shower panel restored to clear glass
Before and after: clouded curved shower enclosure restored to clear glass
Before and after: water-spotted shower glass restored to streak-free clarity
Before and after: mineral-fogged glass panel restored to fully transparent

thick old buildup needs two rounds
our shower is 15 years old and the bottom of the glass was basically white. first pass got most of it, second pass got the rest. newer spots come off in one. thats the only reason for 4 stars

Results vary with the age and thickness of mineral buildup. Very heavy deposits may need a second application. Not for use on natural stone or marble.

Questions, answered

Will this work if my glass is etched?

If it's mineral buildup — even many years of it — yes, that's exactly what ClingFoam dissolves (thick layers may need a second pass). True glass corrosion is rare but permanent, and no product fixes it. The 4-minute test on one patch will tell you which you have, and the guarantee covers you either way.

What surfaces is it safe on?

Glass, mirrors, chrome and stainless fixtures, ceramic and porcelain tile. Do not use on natural stone like marble, travertine or limestone. When in doubt, spot-test somewhere hidden first.

Does it need scrubbing?

No — that's the point. Spray, let the foam sit 3 to 5 minutes, wipe with a cloth or sponge, rinse. Old, thick buildup may want a second application rather than elbow grease.

How long does one bottle last?

Each bottle is 120ml of concentrated foam. A full shower-door restoration typically uses a fraction of a bottle; after the first reset, one bottle covers weeks of quick maintenance wipes. Most customers doing a whole bathroom start with the 3-pack.

Is it safe around kids and pets?

Use it like any bathroom cleaner: ventilate the room, keep the bottle out of reach, and rinse surfaces after use. Full details are on the label.

How fast is shipping?

Every order ships with full tracking — follow each step any time on our Track Your Order page.

What if it doesn't work for me?

You have 120 days. If the minerals didn't move, your money comes back — even on a used bottle.
