With normal use, the sticky pad on the Mogees microphone may get dirty and lose its stickiness. To make it work again, simply peel the sticky pad from the Mogees microphone and run it under water, wiping away any residue. Once cleaned, shake the sticky pad until it is completely dry before attaching it back to the underside of the Mogees microphone.
Sticky pads tend to get better over time with regular washing.
You may find that with the spare sticky pads provided, they can attract layers of dust or dirt quite rapidly and will need washing quite soon after first use.
