#1 How can i clean the stickiness from the black side?
1. Make sure the wine opener is off the charger. 2. Make a paste of baking soda and water and gently scrub the mixture onto the black back with a cloth. 3. Wipe away the baking soda mixture with a damp cloth. Allow the appliance to dry completely before using.
#2 Does the wine chiller produce any condensation during or after use?
The wine chiller is double-walled. You may see condensation on the bottle of wine, but the chiller should not produce condensation.
