How to unstain yellowed feet?

[KayDai]

Hello, I recently got a new bunny named Blueberry, he is so adorable in every way possible but I noticed the old owners let his feet get really yellow, and I was wondering if anyone knows any solutions to help unstain his feet? I know it's not a big deal but I like keeping my bunnies really clean if possible, mainly because Daisy (my other bunny) is all white and I try to not let her sit in anything for to long because those precious white feet are so cute... anyways, any tips are very helpful!

I haven't gotten any nice pictures of Blueberry yet but here's him (I'm waiting for a new phone to arrive to better pics will come soon)

Just keep her new area clean and give it time. Between her grooming herself and losing that stained fur when she sheds, it'll get white on its own.
