We offer mineral free carpet cleaning as part of our high end cleaning, so I have done this a few times before.
Simply unscrew the top and empty spent resin away.
Thoroughly wash out the empty bottle.
Disconnect the drop pipe from the threaded screw top.
Cover the drop pipe with tape whilst you are re filling as you don't want resin getting inside the tube and falling into the lower bulb.
Fill to the top, remove tape and re connect the screw top.
