You've probably noticed that bitter, metallic tang in your morning cup. It’s not the beans. It’s the build-up. Honestly, most of us treat our Farberware percolators or drip machines like they’re invincible because, well, they kind of are. Farberware has been around since 1900 for a reason; those stainless steel percolators are tanks. But even a tank gets gunked up with calcium and old coffee oils that eventually go rancid.
If you don't know how to clean Farberware coffee maker units properly, you’re basically drinking a history lesson of every pot you’ve brewed over the last six months.
I’ve seen people throw these things in the dishwasher. Please, just don’t. While some parts might technically be "dishwasher safe," the high heat and harsh detergents in a modern dishwasher can pit the stainless steel and degrade the heating element over time. You want that classic luster to last? Stick to the manual approach. It’s faster anyway.
The Science of Scale and Why Your Coffee Tastes "Off"
Hard water is the enemy. It’s basically just water with a high mineral content, specifically calcium and magnesium. When that water heats up inside your Farberware, the minerals fall out of the liquid and attach themselves to the heating element and the internal plumbing. This is "scale."
Scale acts like an insulator. It makes your machine work harder to reach the same temperature. According to the National Coffee Association, the ideal brewing temperature is between 195°F and 205°F. If your machine is choked with calcium, it might only hit 180°F. The result? Sour, under-extracted coffee. Plus, those old coffee oils (lipids) stick to the scale. They sit there, getting reheated every single day, turning into a varnish-like substance that smells like a burnt tire.
The Great Vinegar Debate
Most people reach for white vinegar immediately. It’s cheap. It’s in the pantry. And yeah, it works because it’s acetic acid. But here is the thing: vinegar is hard to rinse out. If you don't flush that machine at least four times after a vinegar soak, your next ten cups of coffee will have a distinct salad dressing vibe.
Citric acid is actually the pro move here. It’s odorless, highly effective at breaking down mineral deposits, and rinses clean almost instantly. You can find food-grade citric acid powder at most grocery stores or online. Use about two tablespoons per full pot of water.
How to Clean Farberware Coffee Maker Percolators
The Farberware Superfast Electric Percolator is a design icon, but it has a few "choke points" where grime hides. You’ve got the pump tube, the basket, and that little well at the bottom of the pot.

First, unplug it. Sounds obvious? You’d be surprised.
Start by taking apart the internal assembly. The spring on the pump tube is a magnet for coffee grounds. If those grounds get stuck, the "perking" action becomes weak. Take a pipe cleaner—yes, the kind from a craft store—and run it through the pump tube. If you see black flakes coming out, that’s the "coffee varnish" I mentioned earlier.
For the deep clean, fill the pot with water and your choice of descaler (vinegar or citric acid). Plug it in and let it run through a full cycle.
Wait.
Don't just pour it out. Let that hot acidic solution sit in the pot for at least 20 minutes. This gives it time to eat through the crust at the bottom. After it sits, scrub the interior with a non-abrasive sponge. Avoid steel wool. You’ll scratch the finish, and those tiny scratches will just give coffee oils more places to hide next time.
Scrubbing the Basket
The basket often develops a brown tint. That’s not a "seasoning" like a cast-iron skillet; it’s just filth. A paste made of baking soda and a little water works wonders here. Rub it on, let it sit for five minutes, and rinse. The baking soda is mildly abrasive but won't ruin the stainless steel.

Dealing with Farberware Drip Machines
The drip models are a different beast. They have internal tubing that you can't reach with a brush. If the "Clean" light is blinking on your Farberware programmable model, it’s measuring a restriction in water flow.
- Fill the reservoir with a 50/50 mix of white vinegar and water.
- Place a paper filter in the basket (it helps catch any dislodged scale).
- Start the brew cycle.
- Halfway through, turn the machine off.
- This is the crucial step: Let it sit for an hour.
- Turn it back on and finish the cycle.
Run at least two more cycles with just plain, cold water. If you still smell vinegar, run a third. Honestly, just keep running them until the water doesn't have that "zip" on your tongue when you taste a drop.
That Stubborn Brown Ring
Sometimes the bottom of the stainless steel carafe or the percolator body gets a stubborn brown ring that refuses to budge. Professional baristas use products like Urnex Cafiza, but you can achieve the same thing with a dishwasher pod.
Drop one dishwasher pod into the carafe and fill it with boiling water. Let it sit overnight. In the morning, the brown residue will literally slide off with a light rinse. Just make sure you rinse it incredibly well, as those pods are concentrated.
What About the Outside?
Aesthetics matter. To keep the chrome or stainless steel exterior looking like a mirror, use a microfiber cloth. If there are greasy fingerprints, a little bit of window cleaner on the cloth (not sprayed directly on the machine) will strip the oils without damaging the electrical components.
Frequency: How Often Is "Often Enough"?
If you brew one pot a day, you should be descaling every three months. If you live in a place like West Texas or Arizona where the water is basically liquid rock, you should probably do it every month.
You’ll know it’s time when:
- The machine starts making a louder "hissing" sound.
- The brew time takes more than 10 minutes for a full pot.
- There is visible white crust around the spray head or the pump tube.
Common Mistakes to Avoid
Don't use bleach. Ever. Bleach is corrosive to stainless steel and will eventually cause pinhole leaks in the reservoir or the heating chamber. It also doesn't actually remove scale; it just sanitizes it.
Avoid "home remedies" like lemon juice unless you’re in a real pinch. The pulp and natural sugars in lemon juice can actually cause more problems inside the heating element if not filtered perfectly.
Lastly, don't ignore the cord. Over time, the area where the cord enters the percolator base can get oily. Wipe it down. A clean cord stays flexible and safe.

Actionable Next Steps for a Better Brew
To get the most out of your Farberware right now, start with these three things:
- Perform a "Clear Water" Test: Run a cycle with only water. If the water comes out yellow or has floating bits, your machine is overdue for a deep clean.
- Switch to Filtered Water: Using a simple pitcher filter (like a Brita) reduces the mineral load entering the machine, which means you’ll only have to deep clean half as often.
- Dry the Internals: After your daily use, don't just leave the wet basket inside the pot. Open it up, let the air hit the stainless steel, and prevent that "musty" smell from developing in the first place.
A clean machine doesn't just last longer; it respects the beans you’re buying. There is no point in buying expensive single-origin coffee if you're going to brew it through a layer of old crusty minerals. Take thirty minutes this weekend to strip that scale away. Your taste buds will notice the difference by Monday morning.
