Unless otherwise indicated by the product user guide, you may clean your Rhino device as follows:
DO: Use a dampened, lint-free cloth and wipe gently over all surfaces
DO: Wipe down the unit as frequently as is demanded for its use case
DO NOT: Use harsh chemicals or detergents
DO NOT: Submerge in water
DO NOT: Use abrasive materials
DO NOT: Block ports, vents or other in/outlets
Your Rhino device may have an antibacterial solution for healthcare settings, and due care should be taken not to remove this.
NB: If chemicals are used to wipe down the screen on units not coated with a chemical resistant solution, the oleophobic coating will be removed and fingerprints will most certainly become more pronounced during use. This is not covered under warranty, and a oleophobic solution may need to be purchased and applied to impacted devices in order to restore resistance to natural oils.
