Umm… Around the year 2000 I worked at a couple of different convenience stores in the south, ours were never cleaned, shit they were rarely changed with the exception of Mountain Dew and Dr Pepper because our regulars would tear through them. I remember the lines being clear…ish? They had the embedded nylon or whatever in the clear tube but ours were way nastier than my 18 year old brain wanted to realize.
