HELP! Laquer tabletop cleaners???

I need help! I stained my dining room table! It's a white table w/ an orange water stain. I left a plant in a metal pot on the table to get some sun and it leaked. Now the stain almost seems embedded in the table. Anyone know of any bleaches or cleaners I can use??

Anyone??

oxyclean is the only thing I can think of. Sorry! good luck!
