I read up on that a bit and did the research. Be cautious about what chemicals you put on aluminum baffles. One guy swore by vinegar and or alcohol. I avoided that because of their corrosive properties. My buddy said he uses an Ultra sonic cleaner but I have not.
The suppressor guys told me to use SLIP 2000 Carbon Killer. You have to order it online but it is supposed to be the best.
One video I watched said that nothing will make the baffles 100% clean. I am still learning as I go.
