With continuous use your TipTopTemp will need cleaning to keep it moving freely. The device is solidly made but care should always be used not to bend the damper or hinge.
Boil a quart/liter of water, add a small amount of hand dish soap, the type that will clean grease. Invert the TTT in the hot water for 2-3 minutes.
With a toothbrush and a stainless steel or brass scrub pad, lightly clean the TTT surface and coil.
Rinse TTT and spray lightly with non stick cooking spray to prevent rust.
