I have a friend that was a vintage aircraft owner, he told me about the A/D back in Dec. 2002, and while working as the site quality engineer on board a construction project at NAS Whiting Field, the TrAWing 5 Command Master Chief for AIMD told me that BuAir had sent out a directive to all wings/squadrons, not to use it. He wouldn't even allow it to be in the hangars while he as stationed there. I raced motocross for many years, and Simple Green got a lot of use as it did truly degrease and make maintenance easier. Until some folks began pulling down motors and other aluminum castings. It seeps in gaskets and where two aluminum surfaces mate, and it eats into the raw aluminum causing pitting.

3M Scotchbrite pads was another problem maker that surfaced, it would really make a chrome bore cylinder look nice, and aluminum piston's domes with carbon accumulation like new. Problems began when rings on the pistons started prematurely wearing, and Chrome and alumi-feric cylinder coatings were getting damaged. The pads have an abrasive formulation on them that just doesn't rinse off easily when it is deposited on the metal surfaces. I was told by a master mechanic, and a master machinist also, that they had received directions calling for a three step cleaning process if Scotchbrite pads had been applied to clean any metal surfaces they encountered or worked on.

Sometimes, the easiest way isn't the best way, in the long run.
