Can't say it was just rinse aid but I passed. I smoked marijuana for 60 hours prior to the test and did my best, brushed my teeth, tongue and gums and then flossed and mouthwash (Colgate Whitening Mouthwash with hydrogen peroxide in the ingredients listed) 3 times a day before and during the morning of the test. Test. I plan to buy some oral medication strips and test them myself later, but I can say I used them 15 minutes before the mouth swab and got a negative result pretty quickly.
