是Purple Power清洁液照成的腐蚀
Purple Power官网的FAQ说不要把Purple Power用在铝或不锈钢
在公布结果时能看到有些零件出现white streaks或hazy films
Can Purple Power be used on Stainless Steel and Aluminum?
Do not use Purple Power on Stainless Steel or Aluminum as it could leave white streaks or a hazy film. If accidentally used on Stainless Steel or Aluminum and you have this residue, try buffing with a Metal Polish, such as Wenols or Mothers Metal Polish to restore finish.

我还真找到一个倒霉蛋把铝制消音器泡在Purple Power清洁液 (I wouldn't soak aluminum suppressors in Purple Power (again))
So I left my Thompson SG sitting in a ziplock with an inch or so of Purple Power cleaner/degreaser at the bottom of it (sprayed it to see what would happen to the carbon) for about two days and not only did it remove the Duracoat finish, but nuked the type III anodizing (looks like a splash anno'd paintball gun now) under the Duracoat and seriously eroded/etched/corroded the part that was actually soaking in the liquid. My own fault, it clearly warns of use on paint and aluminum on the bottle. Since the SG is so thick, no harm done, but I am betting that if I soaked my mite in there, it would be trashed.
It was an easy way to get the duracoat off though. Not one I'd recommend, but still. YMMV, but I wouldn't soak it. This was my first time using Purple Power, and it is an impressive cleaner/degreaser I must say.

As promised, here's pics. First one you can see the pitting. I scrubbed off the duracoat with a scotchbright. Took very little effort.

2012年的实验中silencershop使用了Hornady One Shot Sonic Clean Solution而不是腐蚀性的Purple Power清洁液
We learned later that putting a finished part into a sonic cleaner is not a great idea!Our second experiment was much like the first in that we simply pulled apart an AAC Ti-RANT 9 and threw it in the sonic cleaner for 45 minutes.
This time around, we started to see some minor damage to the finish - so we decided it would be a good idea to limit the time that finished parts spend in the sonic cleaner. Unfortunately, the lesson we should have learned was to leave the finished parts completely out!
This time around, we started to see some minor damage to the finish - so we decided it would be a good idea to limit the time that finished parts spend in the sonic cleaner. Unfortunately, the lesson we should have learned was to leave the finished parts completely out!Our third test was the first time we really started to see good cleaning results. This time we used an AAC Element and followed these steps:- Put only the internal baffles into the sonic cleaner for 15 minutes.
- Pulled them out and gently scrubbed them using a copper brush - the carbon pieces flecked off far easier than normal so we only spent a couple of minutes and didn't worry about getting it perfect.
- Put the baffles back into the sonic cleaner together with the tube for an additional 15 minutes.
- After the second 15 minute run, the remaining build-up fell off easily and they looked great! Literally, the baffles looked like new!
Unfortunately, although we only put the tube in for 15 minutes, it didn't fare well at all.This is the kind of thing that would make you sick if you had just spent the time and money to procure a nice new suppressor; so, once again, I advise you to leave the finished parts completely out of the sonic cleaner!Regardless of the damage to the Element finish, we continued with our experiments since we were impressed with how clean the baffles were coming out. Since we have heard so much about how aluminum parts may or may not be damaged in a sonic cleaner, we decided to give that a try using a, fully aluminum, Tactical Innovations Stratus suppressor. Since the Hornady gun cleaning solution is supposed to be safe for aluminum parts, we didn't anticipate any problems - but we hadn't anticipated the finish coming off either... Fortunately, the Stratus came out as clean as the Element - and with no pitting or other damage to the aluminum baffles. I'm not going to guarantee anything; but, we're not going to worry about aluminum baffles going into the sonic cleaner. Overall, I think this is a great tool for cleaning the baffles from take-apart cans since they come out perfectly clean with a minimum of effort. It is unfortunate that the finish can be damaged so easily since that makes it impossible to just throw a sealed can into the sonic cleaner every few thousand rounds. For sealed cans, I think we'll just stick with soaking in solvent and rinsing them out.
