[QUOTE=Zoafan;1482175]Used Simple Green first and then Dawn dish soap.
I found that the normal Simple Green did not work all that well, yes it
cleans but leaves a lot.
What does work like a champ is Simple Green Pro HD heavy duty clearner
It is purple in color and one of the few cleaners that are ok for use on
aircraft.( will not damage aluminum or plastic)
You mix it 50/50 and soak the item let stand 10 to 15 minutes then flush,
do not let dry before flushing.
I get it at one of the large hardware stores.
