First, make sure there is no water in the sink. Pour one cup of baking soda followed by one cup of table salt and then pour a cup of white vinegar. Wait for ten minutes and flush it with boiling water. Then the problem should be solved! Ecofriend does put a disclaimer that if the problem still continues, a plumber should be called. Has anyone tried this method before?
We also found some more ideas on Ask.com. Does anyone have any other home remedys for unclogging a drain? Please share in the comments!
