Can't believe I'm here typing about this but, last night, I accidentally discovered that jizz is a great carpet stain remover...

I had an assignment from university where I had to create cyanotypes, cut a long story short, it is basically an old victorian photography process.

Part of the process involves coating watercolour paper in a special paint, but one night, I accidentally knocked the jar over and spilled it on my carpet. I've had this blue stain on my carpet...
