  • Best: Use up or give away. Dispose of empty container in the garbage.

  • Second Best: Hold for a household hazardous waste collection. In Oregon, call 1-800-732-9253 to find out if there is a hazardous waste collection event scheduled in your community, or call your garbage hauler, local government solid waste department or the Oregon Department of Environmental Quality at (503) 229-5913 or toll-free at 1-800-452-4011.

Alternatives for general cleaning:

  • 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.
