There are a few things you can do to clean a strainer if it becomes clogged:

  1. Pour a pot of boiling water onto the strainer and pour it off, then dry the area.
  2. Use a vacuum cleaner to suck out all the dirt and debris that has built up in the strainer.
  3. Use a plunger to push all of the liquid out of the strainer and into a bowl or sink.
