I bought a smaller bottle of this before, as I only intended on using it for cleaning my PC parts during transplants/rebuilds. Since then it has been used for so many other applications I can hardly count. Not including wanton fire-starting (which is always handy when it comes to leaf-disposal season), its been used to clean parts of computers, cars, you name it. It's stripped paint, cleaned up dog-mess, removed the taint of garlic from a chopping boards...the list goes on!
When people talk about "stuff that is always needed to fix things" i.e. WD40, Gaffer Tape, Zip-Ties and Superglue, this should be added to the list!
