Cloudy glasses every time, no matter how hot the cycle?
Your dishwasher doesn't clean itself. Hard water and food residue build up behind the spray arm and filter with every run, and that's what's fogging your glasses. GlassGuard dissolves it, once a month.
- Dissolves hard water scale before it fogs your glasses
- Breaks down grease and food residue in the filter
- Leaves a Fresh Citrus Scent, not a chemical one
- 24 tablets, a full year's supply, one tablet a month
One tablet, once a month · Only $19.99

You run it every night. It's still not actually clean.
You load it after dinner, hit start, and trust the hot water and soap to handle the rest. Most people never clean the dishwasher itself, because it never occurred to them that it needs it.
Then the glasses start coming out cloudy. There's a faint smell when you open the door. You wipe it down, run it again, and nothing really changes, because the buildup isn't on the surface you're wiping. It's behind the spray arm and packed into the filter, and it's been collecting there with every single cycle.
Why your glasses are actually cloudy
It's not a rinse problem. It's a buildup problem.
Hard water scales up
Every cycle leaves behind mineral deposits from your water supply. They coat the spray arm and your glassware, which is what makes glasses look foggy no matter how hot the wash.
Food residue packs the filter
Grease and leftover food collect in the filter basket over time. That's the source of the faint smell when you open the door, not anything you did wrong.
One tablet breaks it down
Drop a GlassGuard tablet in on a normal cycle, once a month. The citrus-powered formula dissolves the scale and residue while the machine runs, so there's nothing extra for you to scrub.
Think of it the way you'd think about descaling a coffee maker. Hot water alone never fully clears mineral buildup. You need something made to dissolve it, on a schedule, or it just keeps collecting.

"I genuinely didn't know a dishwasher needed its own cleaning. One tablet in and my glasses stopped coming out spotty."

Placeholder review, verified buyerWhat one tablet actually does
Protects your glassware
Dissolves the hard water scale that fogs and etches glasses before it ever reaches them, so your glasses actually come out clear.
Clears the filter, not just the dishes
Breaks down the grease and food residue packed into the filter basket, the part a normal wash cycle never actually reaches.
Fresh Citrus Scent, not a chemical one
No overpowering artificial fragrance. Just a light citrus scent left behind after the cycle finishes.
See the buildup come out, in real time
What changes after one tablet
Before
Foggy, spotty glasses. A faint smell when the door opens. Wiping it down that never actually fixes it.
After
Glasses that actually sparkle. No smell when you open the door. One tablet, once a month, nothing to scrub yourself.
Why this works when rinsing doesn't
Reaches what wiping can't
The spray arm and filter are sealed inside the machine. A tablet dissolved mid-cycle reaches them. A sponge never does.
Built for the machine, not just the dishes
Your regular detergent is built to clean what's on your plates. GlassGuard is built to clean the machine around them.
A full year, not a one-off fix
24 tablets means a tablet a month for a full year, so the buildup never gets the chance to come back.
No extra chore
Drop it in before a normal load. There's no separate cycle to run and nothing new to remember to scrub.

Questions before you order
Can't I just use vinegar instead?
Vinegar can help with light buildup, but it does not reach or break down what's packed into the filter basket or built up behind the spray arm the way a dissolving tablet does during a full cycle. GlassGuard is built specifically to reach those sealed areas.
Will this damage my racks, seals, or the machine itself?
No. GlassGuard runs through a normal dishwasher cycle just like your regular detergent, with nothing extra you need to do differently.
Does it actually work on hard water buildup?
Yes. The formula is built to dissolve the mineral scale hard water leaves behind, which is the most common cause of cloudy, spotty glasses.
Is the scent going to be strong or chemical smelling?
No. GlassGuard is formulated with a Fresh Citrus Scent, not a heavy artificial fragrance. Most people notice it as a light, clean scent after the cycle, not during it.
How often do I actually need to use it?
Once a month, on a normal cycle with nothing else inside the dishwasher. One box of 24 tablets covers a full year.
How is this different from the cheaper tablets on Amazon?
GlassGuard is built around a single job: stopping the limescale and residue that fog your glasses and cause odor, with a 24 tablet box that covers a full year at about $1.67 a month.
Where do orders ship from and how long does it take?
Orders are processed in 1 to 2 days and arrive 5 to 10 days after that.
What if it doesn't work for me?
Every order is covered by a 90-day refund window from the date you receive it.
