Do not torch directly. Always put down gently to avoid chipping/breaking, preferably onto softer surfaces once the banger has cooled to room temp. Clean using a cloth and alcohol & room temp. For deep-clean make sure items are at room temp, leave in 99% alcohol for 2 to 3 hours, remove, rinse with warm water and pat dry then leave outside to dry naturally (particularly) if the item has any kind of inlet holes in it.
