I picked up an ultrasonic cleaner from harbor freight and was thinking about using it on a couple of suppressors. I have a stainless steel Sparrow and a SWR Spectre that are in need of a good cleaning.
I was just wondering what everyone was using for a cleaning solution. I see Brownell's and Midway sell some solutions but I was wanting to try something a little less expensive. Is there a consensus on what will work better (water/windex, dilute Simple Green, dilute Purple Power, etc.)?
Input from anyone that runs an ultrasonic cleaner would be greatly appreciated.
