Because blood from that world has some special chemicals, it evaporates like water overtime, or gets consumed by microbes. It's very rare for that blood to stain, unless you manage to freeze it.

For almost every species native to that world, blood for them is like water to us, as they need lots of iron, so almost everything would go after blood anyway.
