How can i get my urine clean in 24 hours for a drug test ?

Not Medical Advice: There is no way to guarantee clean urine 24 hours before a drug test. Detoxifying drinks are loaded with caffeine and often instruct users to drink lots of water, avoid exercise and cut sugar from their diet. Lab testers will reject diluted samples below a certain concentration whether it has evidence of illegal drugs in it or not. You may or may not be allowed to test again.
