As durable as porcelain isalso the substance remains prone to scratches. Instead of replace the damaged appliance or item, buy a porcelain repair kit and then conceal the scratch. The repair won’t look exactly the same as the surrounding porcelain, but you can make the match close enough that few people will ever be able to tell it is there.
Pick a porcelain repair kit at a color that closely matches the object you wish to mend. If you know the manufacturer of the scratched object, you can contact the company for a kit which has a nearly identical color match.
Wash harassing items thoroughly using dish soap and water, and rinse well. Sinks may have soap buildup, and other things have debris or dirt, all which can may block how well the kit’s mend glaze adheres to the porcelain surface.
Sand the scratch quite gently with emery or even fine-grit sandpaper. The repair kit frequently supplies a little piece of sandpaper. Be careful not to sand beyond the scratch itself since you can damage the rest of the item. Sanding flattens the scrape, knocking down any ridges which might have formed on either side of the flaw.
Clean out the scratch using denatured alcohol to remove sanding debris.
Apply a thin layer of filler using the applicator that comes with the repair kit if you’re correcting a deep scratch — just one which gouges all the way down or into to the base material below the porcelain layer. Filler is not essential for lighter, more shallow scratches. Apply the filler in thin layers and then enable each to dry before adding another layer. Allow the final layer to overfill the scratch.
Level the stitch with a light sanding with emery or sandpaper.
Apply several light coats of glaze above the filler. Allow the glaze to dry completely between coats. Use glaze sparingly with each coat. Try to soften the borders so the glaze does not build up unnaturally.
Sand the dried glaze gently, then buff with a clean cloth.
