|Simple Green in some of its varied forms|
When I last popped into the shop though (Bunnings at Noarlunga Col. - not sure if you are that far south or further North but I know the Marion store also had it in when I popped in there - its in the cleaning aisle) they had the trusty green in a pre-mix back in so I picked up a bottle. Not only is it good for stripping minis, but it actually does what it says on the bottle - all purpose cleaning.
After first picking it up a while back I swiftly converted the missus to its varied uses around the house - its a really good cleaning product. The red version (not pictured) is a great carpet cleaner - perfect for all the little miss's various bodily explosions; while the blue one is a decent window/mirror cleaner (although there are better products out there for that purpose).
I generally chuck things into a deep bowl and cover with diluted concentrate (no real ratio used - a guesstimate is fine, determined with reference to how much gunk needs to be stripped (paint or mold release agent)) or straight out of the bottle for the mixed variety. I then leave it for a number of days - the latest one has been a week but every couple of days I add a few more minis I have stumbled across in my current clean up into the bowl and give it a good stir. Occasionally I'll pop a mini out of the soup and give it a little scrub with an old toothbrush.
After a while its a case of getting the mini out and generally the paint layers will come straight off down to the primer layer - I've had a bit of luck getting that off if I scrape a blade across the surface to break it up a bit and then re submerge it in Simple Green, but generally I leave it as is. I'll give the mini a rinse with warm water to remove any lingering Simple Green and then its good to go again.
Good stuff, and cheap enough for what I use it for. The only thing its ever balked at was the last packet of Heresy Armour I got from FW which had release agent about 2mm thick - I'm slowly having to carve that stuff off as nothing I have hit it with has even touched it yet.
So there you go, a look at the cleaning products in use in the Muppet household!!
