Use a soft cloth or soft-bristled toothbrush to wipe down your Embr Wave 2 on a regular basis.
For tougher scuffs or marks, you can clean your Wave using a cloth or toothbrush that has been lightly dampened with isopropyl alcohol (rubbing alcohol) or water.
Please do not spray your Embr Wave 2 with running water (for example, do not use a pressurized hose or a sink faucet).
Use only a damp cloth, very lightly dampened, when cleaning around the buttons.
