Since we have put our home on the market, all sorts of disasters have happened. The latest: I broke a bubble night light, and the orange liquid inside it stained the corian surface of my vanity top. I have no idea what the liquid is, and I have never found something I couldn't remove. I have tried soft scrub with bleach, leaving it on for about 15 minutes, and it didn't help one bit. I am going to try straight bleach next.

Any ideas, or am I going to have to have it sanded out?
