Darn, darn, double-darn, I thought I had this all sorted.
Just--name me several cleaning substances, would you? Stuff preferably that looks like a cleaning substance. Like here we have Windex to clean windows, and it is a bright blue color.
So. I need something that looks chemical, and maybe sounds like something chemical as well? Or maybe a product both the U.S. and the U.K. would be familiar with? I need something someone would look at and say, "I can't drink that, it looks like X!" and still make sense on both sides of the ocean. Any thoughts?
