Alternatives

• An ounce of prevention will save you pounds of trouble. Use a drain strainer to trap food particles and hair. Collect grease in cans instead of pouring it down the drain. Pour a kettle of boiling water down the drain weekly to melt fat that may be building up.
• Remove the trap and clean out the obstruction with a plunger and/or a plumber’s snake.
• For clogged kitchen drains, pour ½ cup of baking soda, followed by ½ cup of vinegar, down the drain. Cover drain and let sit 15 minutes. Rinse with 2 quarts of boiling water. The pressure created by the heat of the chemical reaction is often enough to open a clogged drain. A good preventive measure is to give your drains a weekly baking soda and vinegar treatment. It will also keep them smelling fresh.
