Be cautious using Simple Green to clean you chain

"Anal military aircraft types go absolutely nuts when they hear about
Simple Green being used to clean an aluminum m/c frame. Cleaning
aluminum with Simple Green type chemicals in an aircraft will get you
suspended for a serious safety violation."

Well, I guess it depends upon your POV re: "Safety"... These guys use Freon to clean their aircraft iirc. Can you say "hole in the ozone layer"?

Thanks for the heads up re: Simple Green....I use it sparingly (and diluted) from time to time on the undercarriage of my 06 FZ6.

In the USAF we have strict rules about which cleaners we use for certain purposes and neither simple green nor freon are on any acceptable cleaners list. In fact it's technically illegal to use something simple like windex on the airplane.

Aluminum - Is it safe to use Simple Green® on aluminum?
When used with caution and according to the instructions, Simple Green All-Purpose Cleaner has been safely and successfully used to clean aluminum. Simple Green All-Purpose Cleaner, Crystal Simple Green® Cleaner/Degreaser, Simple Green Pressure Washer Concentrates, and Pro Series™ Simple Green® Automotive Cleaner have been used on aircraft, automotive, industrial and consumer aluminum items for over 20 years. However, caution and common sense must be used: aluminum is a soft metal that easily corrodes with unprotected exposure to water. The aqueous-base and alkalinity of Simple Green All-Purpose Cleaner can accelerate the corrosion process. Therefore, contact times for unprotected or unpainted aluminum surfaces should be kept as brief as the job will allow - never for more than 10 minutes. Large cleaning jobs should be conducted in smaller-area stages to achieve lower contact time. Rinsing after cleaning should always be extremely thorough - paying special attention to flush out cracks and crevices to remove all Simple Green® product residues. Unfinished, uncoated or unpainted aluminum cleaned with Simple Green products should receive some sort of protectant after cleaning to prevent oxidation.
