How to Descale a Coffee Maker

Descaling Guide

Mineral deposits from water build up in coffee makers and slow brewing. Descale every 1-3 months depending on water hardness.

Removes calcium and limescale buildup from internal pipes and heating elements. Different from cleaning (which removes oils and coffee residue).

Option 1: Commercial Descaler (best) - Follow package directions. Designed for coffee makers.

Option 2: White Vinegar (works) - Use 50/50 vinegar and water.

Option 3: Citric Acid - 1-2 tbsp citric acid in full reservoir of water.

1. Empty machine completely (water + coffee)

2. Fill reservoir with descaling solution

3. Run half a brew cycle, pause 30 min, finish cycle

4. Run 2-3 full cycles with fresh water

5. Brew and discard one pot of coffee to clear any residue

Hard water: Monthly

Medium water: Every 2 months

Soft water: Every 3 months
