Just as long as i rinse it out with hot water will it be ok to use over and over again right?? Its one of those piss cup tests, The ones with the "PH" Stripp on it.. I have been using clean pee in there.. just as long as i keep cleaning it out with hot water it will be ok to use right? It wont like make me get a positive on my next test if i reuse it will it??

Cleaning it couldn't hurt. Just keep using clean urine and you'll be OK.

even if it does, just be say it was a false positive and get a new one and prove that it was a false positive.
