I’m not exactly sure what the liquid is. It’s stinky because it has the smell of the odorant (mercaptan) that is put in LP gas so that we can tell when there’s a leak. The quantity that I cleaned up was too much to be just mercaptan though. Mercaptan is about the stinkiest stuff know to man, and it doesn’t take very much at all to add an odor to a huge quantity of propane.
This is the first time I’ve encountered it in this amount. I’ve had a few drops come out in the past, but this time it was a few tablespoons.
