Help - cleaning high chairs tray

[Yokefleet]

I have today started trying to get ds to feed himself which has resulted in his tray being stained orange. Is there anyway of shifting these marks? Thanks

Flash is quite good for this sort of thing, but needs to be applied asap after he gets down.

If nothing else works, neat Miltons should bleach it back.

Stick it in the sun for a few hours - even a sunny window helps.
