How to remove grass stains from ducks bill

[Poultry mum]

Hey guys I have a show pekin duck however over the summer she’s been eating alot of grass and doing a lot of digging.. just wondering how do I make her bill orange again as her now green speckled bill isn’t exactly of standard that it needs to be… I have a show in just under 4weeks and need her to be in tip top shape thanks.

interesting question. My ducks bills are all kinds of stained I have no idea how to clean them but mine are not show ducks so I let them be but I’m interested to see what others have to say…
