JohnT, I use it for general clean up, i.e. table tops, chairs, computer, floor, etc. but not for anything that comes in contact with the wine. For my glassware, I use either Oxyclean or Dawn dishwashing liquid and a good hot water rinse.
It's got a pretty strong scent. I wouldn't use it. When you say 'safe for a winery', do you mean the floor, the equipment, the sink? I just picked up some B-Brite a couple weeks ago and will be giving that a try soon.
