Question about Esperanza EHA005

I checked the original packaging and everything that came with it. Unfortunately, there were no instructions for use, only on the packaging it says how to use the product. There is no information on descaling.

I bought this for someone else, but I just use plain table vinegar to decalcify any of my humidifiers. Just put it in the bottom part, then set the empty water container in place and it will decalcify the part where the water flows through.
