The real problem
It's not your dishwasher. It's your water.
85% of U.S. homes have hard water running through decades-old pipes. That's why new silverware — even the expensive kind — keeps rusting.
1
Hard water carries minerals
Most U.S. tap water is loaded with dissolved minerals and trace iron.
2
Aging pipes add iron particles
The average American water pipe is over 45 years old — and sheds microscopic rust into every gallon.
3
Every cycle deposits rust
Those particles circulate in hot wash water and settle on your "stainless" steel — as orange rust spots.
Don't take our word for it
Even the manufacturers admit it.
Every major dishwasher brand has a support page about rusty silverware. Here's what they tell their own customers:

40 seconds. That's all it takes to get it.
German engineering
One small stick. Two ways it protects.
Rust Guard works like the sacrificial anode in your water heater — but for your dishwasher. The aluminum attracts corrosion so your silverware doesn’t, while the magnetic core pulls iron particles out of the water.

CoreMagnetic · captures iron particles

MethodControlled comparison test
ResultProven rust reduction
"Rust Guard has an obvious reducing effect on the corrosion behavior of the cutlery samples."
Fraunhofer is Europe's largest applied-research organization — the institute that invented the MP3. Their materials lab tested Rust Guard in a controlled two-machine comparison.
Read the lab reportHow it works
Effortless. Like, actually.
No refills, no measuring, no schedule. One stick works quietly in the background for about four months.
Step 1
Drop it in your cutlery basket
Place it pointing up, like a knife — that's the whole installation.
Step 2
Run your wash
It protects every load automatically — silverware, pots, pans and racks.
Step 3
Swap after about 4 months
The stick visibly darkens as it collects rust — your signal that it's working, and your reminder to replace it.

FAQ
Questions? Answered.
Is it safe for my dishwasher and my dishes?
Yes. Rust Guard is a solid aluminum stick — no chemicals, nothing dissolves into your water beyond the natural protective reaction. It's confirmed food-contact safe by an independent German materials lab and sits in your cutlery basket like any piece of silverware.
How do I know it's actually working?
You'll see it. Over the weeks, the stick visibly darkens — that's the rust it pulled out of your water, collected on the stick instead of your silverware. A dark stick isn't a defect. It's the proof.
Will it help with my already-rusted silverware?
Rust Guard is preventive — it stops new rust from forming. Clean existing spots off once with a standard rust remover, and Rust Guard keeps them from coming back.
When do I need to replace it?
After about 120 wash cycles — roughly 4 months of daily use. When the stick has turned dark and dull across its surface, it's fully loaded and ready to be swapped.
Does it work in hard-water areas?
That's exactly where it shines. Hard water and older pipes carry the iron particles that cause rust spots — Rust Guard was engineered for precisely these conditions, and 85% of U.S. homes have them.
