2. Remove the cap from the A/C condensate line. Simply take your hand and pull up on the cap, it should come right off.

3. Add 1 cup of vinegar to the condensate line. Now all you have to do is add an eighth of a cup of vinegar to the condensate line and put the lid back in place when you’re done.
