What Are the Three Most Important Rules When Using a Dishwasher?

The Unspoken Rules of Dishwasher Etiquette

Alright, quick question—do you just toss your dishes in the dishwasher, shut the door, and hit start without a second thought?

Hey, no judgment. Most of us do. But here’s the thing: dishwashers aren’t magic boxes. They’re powerful little machines, yes, but like any machine, they work best when you follow a few golden rules.

Imagine this: You just unloaded a “clean” glass and noticed a crusty bit of spaghetti sauce still clinging on. Ugh. Annoying, right? That’s often the result of skipping one of the big three. Yep—there are three simple, game-changing rules that can make or break how well your dishwasher performs.

Let’s break them down.


Rule #1: Don’t Overcrowd (Seriously—Just Don’t)

We get it. You want to fit everything in one go. The mugs from this morning, last night’s spaghetti plates, your favorite food-stained spatula from three days ago—it’s like dishwasher Tetris.

But here’s the catch: if water and detergent can’t reach every surface, stuff’s not getting clean. Instead of cutting corners, overcrowding ends up costing you time and energy (because you’ll have to wash those dishes again).

Try thinking of it this way: Every dish needs a little personal space. Not a mile, but enough to let water do its thing. Like a mini spa day—no one wants someone’s elbow in their face.

Quick tip: If you can’t see space between items or they’re nested like Russian dolls, you’re doing too much. Split the load.


Rule #2: Face Dirty Surfaces Inward (Yes, Direction Matters)

Ever pull out a plate that’s mysteriously still dirty while its neighbor is squeaky clean? It’s probably facing the wrong way.

Here’s the thing—dishwashers spray water from the center. So if you’ve got your dirtiest surfaces facing out or tucked behind other stuff, they’re basically hiding from the cleanup party.

Imagine this: It’s like standing behind someone with an umbrella in a rainstorm. You might stay dry, but you’re not getting clean. See the problem?

Quick tip: Load plates and bowls facing the spray arm (usually in the center or bottom) and tilt them slightly downward so water doesn’t pool.


Rule #3: Scrape, Don’t Rinse (Yes, Really)

This one surprises people. You don’t need to pre-rinse your dishes? Nope. In fact, modern dishwashers prefer it if you don’t.

Why? Because many dishwashers have sensors that detect how dirty the load is. If you rinse off every crumb, your machine thinks your dishes are cleaner than they really are—and adjusts the wash cycle accordingly. That means less power, less heat, and… yep, less clean dishes.

But wait, what about baked-on lasagna or dried oatmeal? Scrape off chunks, sure. But don’t waste water rinsing everything like it’s already in a spa.

Quick tip: A quick scrape into the trash or compost is enough. Trust your machine—it’s built for the mess.


Keep It Simple, Clean It Better

So, to recap:

  1. Don’t overcrowd—give your dishes breathing room.
  2. Face the dirty side in—let the spray arm do its job.
  3. Scrape, don’t rinse—your dishwasher actually likes it dirty.

Follow these three simple rules and you’ll spend less time re-washing, less money on water, and more time doing literally anything else. Win-win-win.

And hey—next time you’re loading up, try pretending you’re the dishwasher for a second. Would you be able to reach that bowl shoved behind the pan? Nope. So give your machine a break. It’ll thank you (by actually cleaning your stuff).
