Pour piping hot water into the sink and sprinkle ½ cup of baking soda on top of that. Now, mix 1 cup of vinegar with another cup of hot water and pour it down the pipe. Wait for the explosion. No just kidding. Wait for about 10 mins until the chemical reaction occurs and loosens the food and other stuff. Then pour room temperature water into the sink. I hope this trick works work you if not no worries “call Dailosewa and we will be glad to help.
