Antibacterial nanofoam

Antibacterial nanofoam was a hygiene product used to combat bacteria that could be used while showering. In 1 BBY, Imperial stormtrooper TK-421—who was stationed on the Death Star battle station—accidentally recorded himself via the MSE-6 series repair droid MSE-6-G735Y complaining about how constantly wearing a helmet was ruining his skin and had given him a large pimple. After Grand Moff Wilhuff Tarkin saw the holorecording when the droid collided with his ankle, he sent the droid back to TK-421 with a message and a delivery of antibacterial nanofoam. The stormtrooper recorded a response saying he would shower with the product.
