A hydro-thinner was a device used by crews on planets where sub-zero temperatures were common, such as Hoth. It was used to remove ice from starships and other equipment.

Behind the scenesEdit

The hydro-thinner first appeared in the video game Star Wars: The Old Republic, where it is purchasable from Cantina Vendors on Hoth and used to access one of the datacrons on the planet, which is encased in a block of ice.
