Be very careful with Simple Green. Some versions and I believe ALL older 
versions had Ammonia in them.  I ruined a set of $5,000 outer gear doors 
on an airplane with the stuff  and it has two of them.  They looked nice 
for a while, but they were made of an Aluminum sandwich and the Simple 
Green got down between the laminations where it didn't rinse out well at 
all. That was a VERY expensive cleaning!

Make sure the version you are using does not have Ammonia in it ans is 
approved for Aluminum.
