Have not cleaned it in forever.
Found a local company with some new stuff to try.
Orange citrus cleaner, actually has real oranges in it, can see orange peels in it, smells like OJ :) Retails for 9.95 32oz
Those are how it was
These are after the citrus cleaner and spray it off with a hose
Next I sprayed on the Shine All, not sure on price, but it is basically water soluable armorall on steroids. Looked kind of milky after it was sprayed on.
Then drove it home, letting it dry the whole time
It got my bottles clean :) Took about 10 minutes to spray it all on, took 0 effort. I like my clean bottles :)
