Questions, answered

Everything people ask before buying

Directions / How do I use citric acid as a distiller descaler / cleaner?
  1. Unplug your appliance.
  2. Add hot water to your distiller tank above the mineral line.
  3. Add 3 tablespoons of citric acid powder into the distiller tank.
  4. Let the distiller sit at least 4-12 hours.
  5. Scrub the inside of the tank with a soft brush or sponge, avoid abrasives.
  6. Empty distiller tank and rinse it several times.
Directions / How do I use citric acid as kettle descaler?
  1. Fill kettle halfway with water.
  2. Add 2 tablespoons of citric acid and stir to dissolve.
  3. Boil the mixture if your kettle is safe to boil acidic solutions.
  4. Let it sit for 30 to 60 minutes. (For kettles that shouldn't be boiled with acid, just pour in hot water (not boiling) and let it sit instead.).
  5. Pour out the solution
  6. Use a soft sponge to wipe away any loosened scale.
  7. Rinse thoroughly 2 to 3 times with clean water
Directions / How do I use citric acid as dishwasher descaler?
  1. Empty Dishwasher.
  2. Add 2 to 3 tablespoons of citric acid powder into detergent cup or in a dishwasher safe bowl on top rack.
  3. Run the hottest and longest cycle available. (For best results, choose a "sanitize" or "extra hot" option if your dishwasher has one.)
  4. When the cycle ends, wipe the inside of the door, seals, and edges with a damp cloth to remove loosened buildup.
  5. For extra shine, run a short rinse cycle with just plain water. For extremely heavy limescale buildup, you can make a citric acid paste. Water mixed with citric acid to consistency of paste and apply it directly to the limescale, allow it to sit from 30 to 120 minutes and rub it with a soft sponge afterwards. For severe cases can even let it soak overnight for heavy buildup. Avoid metal damage: Prolonged exposure (especially overnight) can dull stainless steel or corrode sensitive metals like aluminum or zinc. If your dishwasher interior is stainless steel, an overnight soak is usually fine, just avoid direct contact with heating elements or any exposed metal screws. Rinse thoroughly: After soaking, scrub gently with a soft sponge and rinse well to remove all residue. Avoid seals and rubber: If applying paste near seals, don't leave it for more than 30 minutes to avoid possible drying or degradation over time.
