So I took my trusty sigma .40 to the range the other day, got home and cleaned it with the can of break free I just bought the other day. ( this was the first time I have used break free). It cleaned very well. So the next day I go to pick up my cleaning mat ( its one of the ones gander mtn. gives you) and the rubber on the bottom of the mat was stuck to my table and looked to have been melted by the break free. So looking on the can it gives a warning to plastic. So after a few days of my gun being clean I take it and clean it again with remmington shotgun cleaner and hoppes number 9. My question is do you think the break free could have done any harm to my sigma?
