How do I get blue Harpic stains off the loo seat?

[KindleMum]

DS managed to get poo over the top of the loo seat at the back and by the time I saw it, it had set very hard. I thought putting some harpic on it and coming back in 5 mins would be a good plan - except I got distracted and it was probably 20-30 mins and now I have a blue stain on the plastic seat. I don't really want to replace the seat as it's a strange colour to match (rental property) and we're moving soon. Is there a way to get the blue stain off?

Hope someone can answer this

Maybe ordinary bleach? Though it might make it all worse!

it will fade.
just wash with soapy water everyday and it will be fine.
