Hey coffee lovers! Want to up your coffee game? Descale your Smeg machine and get ready for brews that’ll make your day. Here’s the ultimate guide to get you the coffee bliss you deserve.

Why Descaling’s Your Magic Bullet

Scale, that nasty mineral buildup inside your coffee maker, is the enemy of good coffee. Descaling banishes it, giving you:

  • Stronger Coffee: Say goodbye to weak brews caused by clogged pipes.
  • Perfect Temperature: Scale messes with water heating, but no more!
  • Longer Machine Life: Descaling prevents costly breakdowns and keeps your machine running like a champ.

The Secret Behind Scaling

It’s all about your tap water. Minerals like calcium and magnesium are the villains. The harder your water, the quicker the buildup. [Check your water hardness here](External USGS link) to know your enemy.

When to Descale

Every three months is a good rule of thumb, but keep an eye out for these signs:

  • Hard Water: If your water’s got extra minerals, descale more often.
  • Coffee Tastes Off: If your coffee’s getting bitter or weak, it’s time to descale.
  • Machine Runs Slowly: Check the water tank for visible scale buildup.

Tools and Weaponry

  • Smeg-Branded Descaler: The perfect match for your Smeg machine. 
  • Other Coffee Machine Descalers: Check out my article on the “3 Best Descalers” for more options. 
  • Clean Water: Duh!
  • Containers for Mixing & Rinsing: For convenient descaling and cleanup.
  • Cleaning Cloth/Brush: For scrubbing away any stubborn scale.
