I use this guy a lot for Motorcycle engines and the finish is fantastic & I'm really fussy with my restorations. www.aloh.co.uk
There's some info about using Simple Green judiciously & rinseing thorougly on the Simple Green web site: http://consumer.simplegreen.com/cons_faqs.php Look for 'Aluminum'.. ANY even slightly alkaline water based cleaner will oxidize bare Al, simple chemistry. However, that doesn't say don't use it, just don't leave it soaking for long periods of time. Just as you wouldn't leave a bare piece of steel soaking in water w/o it rusting...
Simple clean is a special D'limonine based formula very much unlike other citrus cleaners. Concentrate has a ph of 14 10 to one has a ph of 7... neutral. There are no other so called "citrus" products except for d'limonine in it, no oil, and no acid. it is actually an excellent product for use all over your ride. since it has no oils, it cleans all the dirt out of the interior instead of pushing them down deeper,and eventually causing cracks like many other cleaners do. It is infact Ideal for use before a conditioner or shiner (if you use the right kind without silicone, because silicone is bad for the surfaces to my knowlege.)
