Awesome, thank you for clarifying that. Had a mishap with my 'groon last night, after I covered the steel wool with the vinega, I forgot to loosen the lid to let the fumes/bubbles escape. Pressurized the jar enough to push the lid up & had vinegar all over one of my granite slabs. Wasn't too bad, couple tools don't have a flawless finish anymore, but that's about it.
