So, you know those times when you could swear you see a faint line (mainly on those cheap Wal-Mart tests) but normally those positives don't get darker until after the 10 minute time, so then youre not sure if its an evap by then or your positive got darker ...

I read that if you put some water where you put the pee (once the test is dry) it will remove the evap line and if theres a positive, you will still see it because the water doesnt remove colored lines. Anyone try this and it worked or has anyone heard of the accuracy in it?
