No. To be honest they had no idea what it was or how it ended up in there cupboard lol. Since using it i did some research and it looks like a super cleaner. Clears anything and everything and Is anti static so even cleans electrical goods ect

Used it loads (for longer than I care to be precise about) in an electronics environment. Good stuff.

used it a lot on fruit machines/pool tables/juke boxes etc...good stuff
