I KNOW I've read about this on this site before....is Simple Green good, bad, or indifferent? Isn't there something called Simple Orange? Bear in mind I was in my early 20s in the mid to late 60s, so there is a possibility I'm hallucinating...my senior prom theme song was "White Rabbit" ;-)

Simple Green's New Safe Formula
The classic bottle of Simple Green cleaner has often been the subject of questions in the aviation industry, due to potential corrosion problems. Simple Green was well aware of these concerns and has developed a new forumula--Extreme Simple Green--that prevents corrosion and cleans as well as the old green solution. The problem wasn't that Simple Green was especially corrosive, but that if all of the soap wasn't completely rinsed off, then some Simple Green caught in crevices between aluminum joints could eventually create a dielectric and lead to corrosion. The old formula didn't meet formal aircraft cleaning specifications. The new Extreme formula eliminates the corrosion problem and also meets Boeing's cleaning spec, D6-17487 Revision P. Extreme Simple Green includes an anti-corrosion agent, prevents hydrogen embrittlement, and is safe to use for general cleaning and in pressure washers, parts washers, and dip tanks. Extreme Simple Green is also biodegradeable and solvent-free. Simple Green, phone: 562-795-6000, www.simplegreen.com.
