Descale Coffee Maker with Vinegar

The Problem

Coffee tastes bitter or brews slow. Mineral deposits clog the heating element and water lines.

The Hack

Fill reservoir 50/50 vinegar and water. Run full cycle. Sit 30 min. Run 2-3 plain water rinses.

Why It Works

Acetic acid dissolves calcium deposits that slow flow and add off-flavors.

Pro Tips

• Every 1-2 months depending on water hardness
• Works on Keurigs — run cups until empty
• First pot may taste slightly vinegary, rinse again
• Machine brews faster and hotter after
