While this won’t answer the OP, I feel it’s a related topic. Has anyone made the switch to a non-toxic type of gun cleaner. I few years ago I tried using the Hoppe’s Elite gun cleaners which did a pretty good job. I recently purchased the Roger Advanced gun cleaning products that are water based cleaners. I’m looking forward to trying the Rogers product because over time I’ve grown to dislike using good old No.9 and brake cleaner.
