Its a cleaning product, it was made to cut through grease, break it up , dissolve it. I remember when it was mainly used by mechanics to clean there shop floors and there hands, Hand one was like a cream/gel consistancy . Its in the same place as all the other cleaning stuff, 409, lysol , kitchen ,bath cleaners ect...
Years ago it seemed like I had 5-6 cleaners for all the different jobs around the house, I think I ran out of some stuff and wanted to clean anyway and realized that the degreaser just really worked for almost everything.
It's really cheap , I fine the Walmart brand to work just as well as the "brand names"
I hope your fog lifts.. I struggle with that too

I spent about 8 minutes earlier today trying to remember how to spell the word "when" ..yeah ,, Doh !
