I was on my schedule to dye my hair and have it done in the bathroom. Laziness strikes me because I didn't place any newspaper/magazine on the sink / floor / toilet seat. So, I got stain on the toilet seat and on the sink. I tried to remove it with liquid hand soap using scotch brite, failed! I tried hand sanitizer, failed, rubbing alcohol, failed. I thought of nail polish remover, I was disappointed it didn't remove a bit. I used bleach, a little changes and then last resort is Oxiclean. Viola! it turned out like a brand new toilet seat and the sink as white as pearl. So, if you have stain to remove, try Oxiclean first and I guarantee you that it will solve it. It worked on me.
