How can i clean my white kitchen cupboard from yellow stain

Hi, i hope someone can help me with any tips regarding kitchen cupboard? my kitchen cupboard are white (well the used to be white) and i have tried to clean them from the smoke stain by bleach which i think it changed the colour of my white cupboard, someone told me that that the bleach could change the white cupboard into yellow, now how can i get them white again, i was reading on a website that i should mix the following:


Materials and Ingredients:

Bucket
8 cups warm water
1/2 cup chlorine bleach
1/2 cup baking soda
2 Tbs. Borax
Clean soft cloth


Pour the water, chlorine bleach, baking soda and borax into a bucket and mix.

Wipe any white appliance with the solution, and be sure to take care around carpeting or any fabrics since the solution includes bleach.


does any one know that this will clean my kitchen cupboard and can return the colour to white? please help

thank you very much

think u shud have used that solution in the 1st place, the fact it contains bleach will not change the colur back to white. the fact is the white colour has now been tainted yellow by chemical reaction (with the bleach)
