The Toughest Cleaning Test You’ll Never Have to Do (Because Capsule Already Did It)

If you’ve ever wondered whether a compact, water-sipping, no-plumbing, planet friendly countertop dishwasher can actually handle real-world messes… then do we have a story for you.

Because before Capsule earns the right to sit in your kitchen looking sleek, it has to jump the highest hurdle of the dishwasher world: certification cleaning tests.

They’re the industry’s most brutal, (British) standardized, lab-grade torture ritual for dishwashers.

As founders, nothing prepared us for the level of detail, mess and overall difficulty that these tests put us through.

To put it in context, it’s 70 pages’ worth of instructions, ingredients, timings, temperatures and stain-application methods. The Ivy League entrance exams of filth.

And, the reason we can confidently say:

Capsule doesn’t just clean. It conquers.

First: you must prepare the stains. Yes, really.

To keep the test fair, all stains must be professionally prepared.

This is where it starts getting surreal:

• UHT milk cooked at exactly 780W for 4 minutes, then again at 150W for 10 minutes.
  (Because apparently it isn’t enough to dry up the milk, it has to have been sent to another dimension)
  
• Black tea, orange pekoe, brewed with laboratory precision.
  Six grams per liter exactly. Orange pekoe is a particularly stainy kind of tea, as we learned.
  
• Minced meat and eggs in a 1:1 pork-to-beef ratio, with 50 grams of egg per 150 grams of meat.
  There was nothing appetising about this test, in case you were wondering by now. The point here was to create a protein mutant.
  
• Spinach applied with a brush.
  Finger-painting the stains would simply be barbaric.
  
• Margarine scraped on at room temperature.
  For optimum oiliness.
  
  

It wasn't pretty.

Then the stains go on… everything.

Once all that gourmet chaos is prepared, it’s lovingly smeared, brushed, dolloped, spread, and blasted onto dishes and utensils. Then dried with:

• a thermal cabinet at 80°C,
• an air-conditioned room at 23°C and 65% humidity,
• and frankly, more discipline than most of us apply to our taxes.

The resulting dishes were academic-level dirty.

And then: Capsule goes in.

This is where the magic happens.

The trays of spinach-porridge-meat-egg-tea-margarine madness go into Capsule, and despite its compact size and tiny water usage, Capsule stepped up.

“Oh, this? Piece of cake,” It said. Probably.

Its high-pressure spray arms, stainless-steel interior, and energy-efficient heating element attacked stains that were engineered to ruin the day.

Capsule came out the other side with:

✨ clean dishes

✨ zero drama

✨ and incredibly low water and energy consumption

All from a dishwasher smaller (and better value!) than some of your Amazon splurges.

Finally — the After. Pure satisfaction.

The “after” photos look as if the stains were never there. Plates, cups, glassware, cutlery. All spotless and lab-verified.

These were the worst stains the industry could legally throw at us, and Capsule didn't flinch.

We examined the results like proud parents, and frankly, we weren't that surprised. We had poured all our energy on Capsule for months, researching, adjusting and perfecting it into a mean, lean, cleaning machine.

Why do we care so much about this?

Because at Loch, we’re obsessed with engineering things properly, to make sustainable living effortless for you.

Capsule and Capsule Solo are built for tiny homes, rented apartments, off-grid cabins, caravans, offices, micro-kitchens and every place a full-sized dishwasher can’t go.

They’re compact, water-efficient, beautifully designed, and (as certified by our trials in Dishwashing Mordor) legitimately powerful.

The joy of a tiny dishwasher is great.

But the joy of a tiny dishwasher that cleans like a full-sized machine? That’s the part that changes your daily life.

Dishes stop piling.

Mental load drops.

Sinks stay empty.

Arguments vanish.

You get your time back.

So yes, Capsule passed. With flying (and sparkling) colours.

We took the world’s strictest dishwasher tests and gave them to the world’s smallest one. And Capsule dominated.

Because if something is going to live on your countertop, it should earn its place. And Capsule absolutely has, and it's got the papers to prove it.
