Use preventative measures. There's an old saying that an ounce of prevention is worth a pound of cure. That's true for cleaning and polishing. If soil is allowed to accumulate, the task of removing it becomes more difficult. Thus, wiping spills when they occur can prevent stains and eliminate the need for tough specialty cleaners, which often are more toxic and more harmful to surfaces.
Chlorine bleach can dull the shiny finishes on sinks, bathtubs and other porcelain enamel surfaces.
Once the surface becomes dull and rough, it will get dirty faster and stain deeper. Wipe away grease and spills in the oven after each use, or put a liner on the oven bottom to catch spills and you can reduce the need for an oven cleaner. Cover sink and shower drains with a screen to keep out food scraps and hair. Don't pour grease down the drain. Collect it in an empty can and put it in the trash.
