www.hazard.com. Go to the MSDS site nearest you and type "gun scrubber" into the box. There is only one to choose from, being the product in question.
None the less, I would guess that it could be substituted for DCM, as long as the boiling points are far enough apart to properly distill.
I personally was able to get over a liter of DCM from zipstrip in less than an hour by filling the bathroom sink with hot water and letting it run slowly (allowing the overflow to drain down that little hole at the top) then wrapping a bunched up paper towel around the 3-way adapter and placing it in the can to create a seal, then placing the can in the sink. within 20 minutes you will get DCM coming over.
