Daily Cleaning
Before you start up the machine everyday and close it out at the end of everyday, you’ll need to sanitize the door and its surrounding components to keep it clean and the product tasting fresh. Here’s how you do it:
Closing Cleaning Procedures
- Step 1. Prep the sanitizing solution – For this, you’ll need to fill an empty cleaning bucket with hot water and 1 packet of McD sanitizer packet for every 2-1⁄2 gallons of water. Next, use the brush to mix the powder until it dissolves in the water.
- Step 2. Clean the dispensing spout area and spinner plate – Using the door spout brush, clean the dispensing spout, spinner plate, nozzle, handle and piston area several times with the sanitizing solution.
- Step 3. Sanitize the spigot area and spout – Next, spray the spigot area and spigot area, handle, spout and the nozzle’s interior with the sanitizing solution.
- Note: Do not spray sanitizer onto the photocell, as this could damage the machine.
- Step 4. Clean the drip tray, drawer & hopper cover – Sanitize and rinse the drip tray, drawer and hopper cover in the sink. Thoroughly dry them before reinstalling.
- Step 5. Clean the exterior – Wipe down the freezer door, front panel and other exterior components that may be prone to moisture buildup or food splash.
- Step 6. Detach and clean the syrup pick up tubes – The pick up tubes are currently sitting in the syrup jugs or are attached to the syrup bags. Remove or disconnect these now and set the syrup jugs/bags aside for later. Then, wipe down the lines with a fresh, sanitized cloth.
- Step 7. Sanitize the syrup lines – Place the pick up tubes in the bucket containing the sanitizing solution. Press the “STOP” button followed by the “COLORED CUP” button twice. Let the pump run for 1 minute before pressing the “STOP” button again.
- Step 8. Repeat step 6 for all syrup lines – Repeat the sanitization process for each of the syrup lines.
- Step 9. Put the milkshake machine in PROD mode – Once you’ve finished sanitizing all the syrup lines, place all the tubes into the bucket and press the “PROD” button.
Opening Cleaning Procedures
- Step 1. Repeat steps 1-5 from Closing Cleaning Procedures – Repeat steps 1-5 from above. Make sure you prep the sanitizing solution correctly and clean the dispensing spout, spinner plate, spigot and exterior.
- Step 2. Take the pick up tubes out of the sanitizing solution – Remove all the syrup lines from the cleaning bucket and place them on a fresh cloth in the cabinet.
- Step 3. Empty the syrup tubes – Next, press the “STOP” button followed by the “COLORED CUP” button twice. Press the “STOP” button once all remaining sanitization solution has been purged from the lines.
- Step 4. Repeat the steps 2-3 for all syrup lines – Empty all the syrup lines of the sanitizing solution as outlined in steps 2-3.
Cleaning the Keyboard
It’s a good idea to relieve the keyboard of all its greasy fingerprints and smudges at the end of each shift. Since it’s a touchscreen, you’ll want to lock it before accidentally change its settings when To do this, follow these Carpigiani milkshake machine cleaning instructions:
- Step 1. Press and hold the “CLENOUT” button – Press and hold the “CLENOUT” button for a total of three seconds or until the LED light flashes.
- Step 2. Wipe down the keyboard – Using a damp, clean cloth, wipe off any dirt, food debris or fingerprints off the keyboard panel.
- Step 3. Unlock the keyboard – Don’t forget to unlock the keyboard again when you’re finished! Just press and hold the “CLENOUT” button again for 3 seconds until the LED flashes.
