I use BP all the time, Lavender is my favorite. I buy it at Joanns when I have a 40% off discount and buy the gallon jug. It can also be diluted. I'm not surprised but sorry for you that it took finish off. I would have expected that. and yes the overspray is gummy. again, not surprised. This is not water you are using. I feel like it starches my fabric with a wonderful feel. I understand some people have a sensitivity to the smell. I love it!
