A Nespresso machine losing its crema or taking longer to brew a standard 1.35-ounce espresso shot usually means calcium scale has choked the internal thermoblock. You don’t need to send it in for service. Flushing the system with a dedicated lactic acid descaler takes about 15 minutes and restores the proper water pressure and temperature required for optimal extraction.
Gather Your Cleaning Supplies
Skip the DIY vinegar solutions. White vinegar leaves a lingering acetic acid taste in the plastic lines and isn’t strong enough to dissolve heavy calcium carbonate buildup. Grab a dedicated lactic acid-based solution like the official Nespresso Descaling Kit or Urnex Cleancaf Powder. You will also need a container that holds at least 34 ounces (1 liter) to catch the purge water, plus a microfiber cloth to wipe down the exterior casing and optical barcode reader on Vertuo models.

Descaling Your Nespresso Machine
Empty the capsule container and drip tray completely. Pour one packet of descaling liquid into the reservoir and add 17 ounces (0.5 liters) of fresh water. Enter descaling mode—on most Original line machines, you hold both the Espresso and Lungo buttons for three seconds until they blink. Press the Lungo button to flush the entire reservoir through the brew head into your catch container. Refill the tank with the purged liquid and run it through a second time.

Cleaning the Coffee Outlet and Drip Tray
Coffee oils turn rancid quickly when exposed to air, leaving a bitter residue right at the extraction point. Remove the drip tray and capsule bucket, washing both with warm water and mild dish soap. For the brew chamber itself, insert a Caffenu Cleaning Pod just like a regular coffee capsule. Brew a small shot to release the foaming agent, let it sit for two minutes to break down old oils, then flush the system twice with plain water.

Maintenance Tips for Long-Term Care
Eject spent capsules immediately after brewing rather than letting them sit in the chamber, which prevents the piercing needles from clogging with dried grounds. Run a blank water shot before your first coffee of the day to preheat the lines, and another blank shot after your last cup to flush out residual oils. Empty the water reservoir every evening and let it air dry to prevent biofilm buildup along the bottom edges and intake valve.

Final Thoughts
Run a blank water cycle right now to clear out today’s coffee oils. Order a descaling kit if it has been more than three months since your last deep clean, and set a calendar reminder for your next flush.
