I am pretty sure he was looking for an answer to his question not your stuck up opinion!!! I have heard the vinegar if swished in your mouth under an hour before the test will do it but I have never done it so I can't be 100 % positive but I will tell you I had urine tests for 3 years and I drank a half cup of vinegar and hour before the test every month and passed every month!! I would use the vinegar and the mouth wash I don't think peroxide will do much..good luck and let us know how you did!!
