Dissolved PVA has high adhesive properties. For optimal performance of the PVA Removal Station and to prevent problems such as excessive wear of parts, make sure to regularly clean the device. This should be done at least once a month, or with every water exchange.
As this requires dismantling parts of the PVA Removal Station, all cleaning actions can be performed at the same time.
When exchanging the water, make sure all PVA residue is removed from the inside of the container. This will give the best results for the next PVA removal cycle.
- Empty the container as described in the Disposal of wastewater page.
- Take the rotor by its center pin and gently pull it straight upwards. Place the rotor aside; this will be cleaned next.

| Remove the container to empty it | Remove the rotor from the rotor pin |
Caution: Do not tilt the rotor when removing it, as this could damage the rotor pin.
- Remove the rotor bearing ring and place it aside.
- Fill the container with lukewarm water; the container should be half-full.
- Remove any PVA residue with a soft brush.
- Rinse the container.
Note: Repeat steps 4 – 6 until all PVA residue is removed and the container is completely clean.
- Clean the outside of the container with a soft, damp cloth.
- Dry the container before the next use. Leave to air-dry or use a soft cloth.
Next, clean the magnetic rotor as described in the second tab.
The magnetic rotor is fitted at the bottom of the container. When cleaning the container, the rotor must be removed anyway, so move on to clean the rotor next.
Note: If you need to clean just the rotor, for example for troubleshooting purposes, make sure to first empty the container. Remove the rotor from the container by holding it by its center pin and gently pulling it upwards. Do not tilt the rotor when removing it, as this could damage the rotor pin. Remove the rotor bearing ring from the container and place it aside.
- Rinse the rotor with lukewarm tap water.
- Remove any PVA residue with a soft brush.
- Place the rotor bearing ring back over the rotor pin located at the bottom of the container.
- Hold the clean rotor by its center pin again and make sure the fins are facing upward.
- Gently but firmly push the rotor onto the pin at the bottom of the container.
- Apply pressure until the rotor is fully in place; the rubber O-ring of the rotor pin should be pushed through the rotor completely.

| Align the rotor with the rotor pin | O-ring on the magnetic rotor |
Tip: The rubber O-ring locks the rotor in place. Especially at first use, the rotor fixation can be difficult due to friction. Apply some water to the pin before placing the rotor to reduce the friction.
Note: If the PVA Removal Station will not be used for longer periods of time, do not install it back in the container, but store it in the rinsing basket as described on the Storage page. This prevents the rotor from sticking to the bottom of the container.
Next, clean the docking station to complete this maintenance procedure.
Make sure the docking station is free from any PVA residue, as this can cause the docking station and container to stick together. The docking station should always be completely clean and dry before the next use.
- Clean the outside of the docking station with a soft, damp cloth.
- Immediately dry all surfaces with a soft cloth.
- Allow the docking station to fully air-dry before the next use.
Caution: Only use a damp cloth to clean the docking station. Never use scouring pads, abrasive cleaning agents, or aggressive liquids such as petrol or acetone to clean the device. Never immerse the PVA Removal Station docking station in water or any other liquid.
Now that the PVA Removal Station has been completely cleaned, it is ready for continued use. Fill the container with fresh water to remove the PVA support structures from your next print. Alternatively, if the PVA Removal Station will not be used for a longer period, put it in storage after cleaning.
