Bathroom surfaces are made of a large variety of materials, but porcelain could be found on many fixtures including bathtubs, toilets, sinks and tiles.

Porcelain is a manufactured material that is largely made from clay. While it's considered to be a durable material, it should be properly maintained to avoid cracks or damage to the finish.

Catherine Gervino of highly rated TLC Cleaning Service in Rye Brook, N.Y., says there are a number of products on the market that are safe to use and will get porcelain sparkling.

"I like Scrubbing Bubbles or the dollar store equivalent," she says. "I recommend spraying the [surface] with one of these products, scrubbing with a sponge, rinsing with clean water and buffing dry."

The New York City area house cleaning professional warns against using oil and chlorine-based products, as these can stain tile grout.

Rick Sicro, of GM Holly Maids in Rancho Santa Margarita, Calif., says if you have tough stains on tile or in a toilet bowl, you could use a pumice stone and not worry about scratching the surface.

"You can almost use it on anything," says the Los Angeles area house cleaning expert. "Porcelain is pretty resilient, so you don't really have to worry too much."

If there's a surface in your house you're not quite sure how to care for, consider hiring the help of a professional house cleaning company. Lisa Niden recently hired Boston house cleaning professional Kristen McIntosh to clean her "relatively large, old house with lots of dust and a dog."

"Kristen was not only punctual and reasonable but absolutely professional," Niden says. "I plan to schedule her on a monthly if not bi-monthly basis."
