I went and got another protox 10 day cleanser and now after that cleanser I am still dirty. I have been clean for 13 days and I have completed the 10 day cleaner. However im still testing dirty? I have exactly 6 days till im supposed to go back for my next test.
Which goes to show what its been stated all along - that magic "detox" cleansers are a total scam.

On my last home drug test which was today I was able to see a very slight line in the cup which means a weak positive. It was positive though.
If a faint line appears in the T region its a negative, not a positive or a "weak" anything.

I plan on taking 2 acetaminophen 2 hours before my drug test 500mg each.
This will do absolutely nothing to pass a U/A.

So my question now is what can I do to get clean in 6 days? I am currently taking 1000mg of timed release niacin every morn and every night starting tonight(not flush free).
This is an old urban myth. Niacin does nothing to help pass a U/A. Besides, taking more niacin than the recommended daily value can have some serious health consequences.

I am also going to drink 1 gallon of water every day for the next 3 days. After that im switching to gatorade.
Drinking a bunch of water days before the test is of no help. THC is not water-soluble, so you cannot wash THC out of your body like you can wash dirt from clothing.

However, drinking fluids can effectively (but temporarily) dilute the THC metabolite (THCA) concentration that is present in the bladder. Diluted to where the urine sample registers below the cutoff thresholds of the drug screen. Because this action is only temporary, drinking fluids is only effective on the day of the U/A.

I will run every day starting tomorrow morning.
If you have 3 days or less before the U/A, you need to avoid exercise and other fat-burning activities. When fat cells burn, the stored THCA is released back into the bloodstream and eventually end up in your urine. Instead of trying to burn fat, youd want your body to be in "storage mode" - be as lazy as possible to avoid releasing a bunch of THCA, which will all end up in the urine in your bladder to be detected.
