How do I clean a heat management device?
For minor cleaning after each session, you can use a brillo pad or some rough steel wool to scrub off the burnt shisha residue from the bottom of your HMD. For tougher, more caked-on residue, allow your HMD to soak in hot water and dish soap for at least an hour to loosen up the residue before scrubbing. Over time, it is normal for a heat management device to develop slight discoloration - this will not affect its quality or performance.
