Instructions

1

Pour a small mound of salt into a bowl. Drip lemon juice into the salt and mix the two with a spoon. Continue adding lemon juice and mixing until the salt and juice form a paste.
2

Apply the paste to any rusted stains or rusted metal exposed by chipping porcelain. Wipe the paste on with the spoon you used to mix it.
3

Allow the mixture to sit overnight, then wash it off with a damp cloth. The rust should be gone.
4

Sand down the edges of any chipped porcelain with an emory cloth.
5

Mix porcelain repair compound with a high-gloss, alkyd-based paint matched to the color of the enamel. Create another batch if the mixture ends up differing in color from the porcelain, using less repair compound.
6

Apply the compound to the chipped porcelain. Scoop up some compound on the edge of a razor blade, fill in the hole, then use the blade to smooth the compound to match the contour of the enamel.
7

Allow the compound to dry. Remove any dried excess compound using a cotton swab soaked in fingernail polish.
