Well after the film coating from a crap batch of UV dye and the food coloring i used to cover up the goo the UV dye left behind i thought i should clean it out. Its weird being able to see through the tubes again. I couldnt get the sort of blue tint off the inside of the Maze3 . The tygon r-3603's wall was twice as thick too which i didnt know when i orderd it since it never said so it was hard to get on the fittings.
