What is the safest (least toxic to people) APC that can be used on aluminum? Looking for an APC for light Engine Cleaning and Wheel Cleaning that can tackle vinly, door jams, exteriro trim. You know the holy grail of APC.. 
I am no chemist, but I have been reviewing the MSDS sheets for quite afew APC's and I am not sure which is more safe. All most all APC are rated a health of 1 (4 being the most toxic), with only Meguiars being health of 2. Since the meguairs seems really toxic to me it makes me think there is alot of play in the 1 range. I have started looking into degreaser that are not stricly automotive (solution 2000, safe care sc-2000, and the GGT line).
Running list of APC'? (let me know of any I haven't thought of)
Opti Powerclean
Simple Green
Meguiars
HD Total Degreaser
DP Total Exterior
Purple Power
Adams APC
GGT Speed Clean Concentrate (green degreaser on the EPA design for environment list, seems promising) Products - Global Green Technology, LLC
PS21TAW
Any thoughts?
Thanks!
