Wow thanks for the tip on TSP! Wouldn't have thought about it, and left it in there like u did! I've got comments ab home cleaners that "kill 99% of viruses" and on why they use what they use in restaurants, but this is an old thread... I used to work in the restaurant industry (love it) but now I make jewelry, and use a big daddy torch (acetylene), hate the butane ones, unless making a couple crème brûlées, but that's what I use for tools... I'm comfortable with them... If you're not... Don't use them, find something else!
