How to use citric acid to clean appliances (and stop throwing money away on chemicals)

One container, one scoop, and goodbye to half a shelf of cleaners

Coffee maker, washing machine, dishwasher, kettle, iron, fridge... each appliance with its specific product, its brand, its plastic packaging, and its "premium descaler" price. In the end, the shelf under the sink looks like a small supermarket. The good news is that almost all that arsenal can be replaced by a single product: powdered citric acid, the same compound that gives lemon its characteristic flavor, but in a concentrated, ready-to-use version.

First things first: what is citric acid and why is it so cool?

Citric acid is that compound that makes lemon taste like lemon. In its powdered version, it's a brutal ally for home cleaning: no additives, no artificial aromas, no aluminum, no anti-caking agents, and not tested on animals. In other words, what a true ecologist wants to see on the label.

Its cleaning superpowers:

• 💪 Effectively removes limescale, without endless scrubbing.
• 🚿 Unclogs pipes and drains without corrosive products.
• ✨ Polishes stainless steel, glass, and ceramic.
• 🦠 Naturally disinfects kitchen and bathroom surfaces.
• 👃 Neutralizes odors without leaving a trace of chemical fragrance.
• 💄 Suitable for homemade cosmetics: bath bombs, solid shampoos, and much more.

And what's more, ours includes a 25g dosing scoop inside the packaging so you don't have to weigh or calculate. Convenient, sustainable, and ready to use.

How to use citric acid in your appliances (scoop included)

1. ☕ Coffee maker and capsule machine — goodbye to limescale taste

If your coffee no longer tastes the same, the culprit is almost certainly accumulated limescale. You don't need any expensive branded descaler: citric acid will solve it.

1. Fill the tank with 1 liter of water.
2. Add 1 level scoop (25 g) of citric acid and dissolve well.
3. Run a descaling cycle or let the water run without capsules.
4. Run two more cycles with clean water to rinse.

🔁 Repeat every 1-3 months depending on coffee maker usage and water hardness.

2. 🫙 Washing machine — clean inside what cleans outside

The drum, the detergent drawer, the hoses... everything accumulates limescale, residue, and bacteria without us seeing it. A maintenance cycle with citric acid and your washing machine will live many more years. If you also notice a bad smell when opening the door, we have a specific guide on why the washing machine smells bad and how to fix it.

1. Pour directly into the drum (not the drawer) between 4 and 6 scoops (100-150 g).
2. Set a long cycle at 60°C with an empty washing machine.
3. When finished, wipe the door seal with a damp cloth.

🔁 Repeat every 2-3 months.

3. 🍽️ Dishwasher — the natural descaler you didn't know about

Limescale clogs the dishwasher spray arms and makes dishes come out dull. Simple, natural solution without spending on industrial tablets.

1. Put 1.5-2 scoops (40-50 g) in the detergent compartment or at the bottom of the appliance.
2. Run a full cycle at 60-70°C with an empty dishwasher.
3. If you notice residue, run another cycle with only water.

🔁 Repeat once a month.

4. 🫖 Kettle — the before and after will surprise you

The kettle is perhaps the appliance where limescale is most noticeable. You'll see the difference after the first cleaning with citric acid.

1. Fill the kettle to the maximum mark.
2. Add 1 scoop (25 g) of citric acid.
3. Bring to a boil and let stand for 20-30 minutes.
4. Discard the water, rinse well, and boil again once with only clean water.

🔁 Repeat every 2-4 weeks if you have hard water at home.

5. 🔵 Steam iron — make it steam properly again

Limescale clogs the steam holes and the iron stops working well, or worse, stains clothes. Easy to solve.

1. Mix half a scoop (≈12 g) in 500 ml of water.
2. Fill the iron's tank with that solution.
3. Set the iron to medium temperature and activate the steam several times over an old cloth until the tank is empty.
4. Repeat with clean water to rinse.

🔁 Repeat every 1-2 months.

6. ❄️ Fridge — natural disinfection without toxic products near your food

We don't want harsh chemicals where we store food. Citric acid is gentle, safe, and eliminates odors and bacteria without leaving dangerous residues.

1. Dissolve half a scoop (≈12 g) in 500 ml of warm water.
2. Wipe down walls, shelves, and drawers with a damp cloth.
3. Rinse with another clean damp cloth and dry thoroughly.
