I ran across another thread about cleaning/not cleaning Glocks and some people said they used an Ultrasonic cleaner. Some said they use Simple Green with it. I remembered that Simple Green was suspected of being damaging to certain plastics and metals. I found the following which I thought would be helpful to post for others to be aware of:
TLDR: Do not use (regular) Simple Green on guns
"While Original Simple Green
is an excellent all-purpose cleaner/degreaser, it was not designed for long-term storage of bike chains or other parts
....Under no circumstances should anything be stored in any formula of Simple Green.
The new product, called ExtremeSimple Green Aircraft & Precision Cleaner
, has heightened non-corrosive qualities, making it perhaps more suitable for high-tech bike alloys, painted surfaces, rubber and plastic parts. To date we have only promoted this product in the aviation industry. If it turns out to be better for bicycles and bike parts as well, then we’d certainly like to let people know about that.
Aircraft forums warned against using regular simple green for any purposes. Not just storing parts in it.
Thus my warning. I'll look for and provide more information but the fact that they have a special "non corrosive " and "rubber plastic safe " version speaks volumes
