Nails..

So recently i've been painting my nails regulary and they've stained my nails yellow!
I've seen a remody saying buff the top of your nails and soak them in lemon/lime water , and this should help the nails go back to the normal colour.
I'll keep you updated to tell you all if it works! But if it doesn't , seems like i'm going to have to paint my nails regulary LOL.
A way to prevent stained nails is to apply a base coat then the nail colour then the top coat ! Take the advice , i regret it !
