To clean a sticky spatula fill the sink with hot water and add some Dawn Dish Soap to the water.
Then allow the sticky spatula to soak for 30 minutes to an hour in the water to help the sticky residue come off the spatula.
Then you can also use some baking soda and vinegar to remove really sticky residue from the spatula.
Also you can clean a sticky spatula by mixing some cutting liquid dish soap and water and wash the spatula and handle thoroughly.
After the spatula is dry, use rubbing alcohol and a clean cloth to wipe the handle and spatula down with.
If the sticky surface remains, mix some baking soda with water to create a thick paste that is about the consistency of toothpaste.
